Answer: What subject is this? Like seriously, it's not even a question at all. Please clarify and explain which subject it is,  and what the question actually is.

Explanation:

Answer:The ionization energy of an atom is the amount of energy required to remove an electron from the gaseous form of that atom or ion.

1st ionization energy - The energy required to remove the highest energy electron from a neutral gaseous atom.

For Example:

Na(g) → Na+(g) + e- I1 = 496 kJ/mol

Notice that the ionization energy is positive. This is because it requires energy to remove an electron.

2nd ionization energy - The energy required to remove a second electron from a singly charged gaseous cation.

For Example:

Na+(g) → Na2+(g) + e- I2 = 4560 kJ/mol

The second ionization energy is almost ten times that of the first because the number of electrons causing repulsions is reduced.

3rd ionization energy - The energy required to remove a third electron from a doubly charged gaseous cation.

For Example:

Na2+(g) → Na3+(g) + e- I3 = 6913 kJ/mol

The third ionization energy is even higher than the second.

Successive ionization energies increase in magnitude because the number of electrons, which cause repulsion, steadily decrease. This is not a smooth curve There is a big jump in ionization energy after the atom has lost its valence electrons. An atom that has the same electronic configuration as a noble gas is really going to hold on to its electrons. So, the amount of energy needed to remove electrons beyond the valence electrons is significantly greater than the energy of chemical reactions and bonding. Thus, only the valence electrons (i.e., electrons outside of the noble gas core) are involved in chemical reactions.

The ionization energies of a particular atom depend on the average electron distance from the nucleus and the effective nuclear charge

These factors can be illustrated by the following trends:

alternatetext

1st ionization energy decreases down a group.

This is because the highest energy electrons are, on average, farther from the nucleus. As the principal quantum number increases, the size of the orbital increases and the electron is easier to remove.

Examples:

I1(Na) > I1(Cs)

I1(Cl) > I1(I)

1st ionization energy increases across a period.

This is because electrons in the same principal quantum shell do not completely shield the increasing nuclear charge of the protons. Thus, electrons are held more tightly and require more energy to be ionized.

Examples:

I1(Cl) > I1(Na)

I1(S) > I1(Mg)

The graph of ionization energy versus atomic number is not a perfect line because there are exceptions to the rules that are easily explained.

EnergyGraph

Filled and half-filled subshells show a small increase in stability in the same way that filled shells show increased stability. So, when trying to remove an electron from one of these filled or half-filled subshells, a slightly higher ionization energy is found.

Example 1:

Example1

I1(Be) > I1(B)

It's harder to ionize an electron from beryllium than boron because beryllium has a filled "s" subshell.

Example 2:

Example1

I1(N) > I1(O)

Nitrogen has a half-filled "2p" subshell so it is harder to ionize an electron from nitrogen than oxygen.

Explanation:

The energy needed to remove an electron from an atom or ion's gaseous state is known as the ionisation energy of that atom.

The energy needed to expel the highest-energy electron from a neutral gaseous atom is known as the first ionisation energy.

The amount of energy required for an isolated, gaseous atom to discharge one electron, creating a cation, is known as the ionisation energy. Typically, this energy is represented as kJ/mol, or the energy required for every atom in a mole to lose one electron.

The amount of energy needed to ionise an atom or ion in a gas is known as the ionisation energy. The energy needed to liberate one mole of isolated gaseous atoms or ions from one mole of electrons is known as the first or initial ionisation energy, or Ei, of an atom or molecule.

Answer: These are the methods of energy transformation

Explanation:

Explanation: hope this helps

1. Heat transfer describes the flow of heat (thermal energy) due to temperature differences and the subsequent temperature distribution and changes.

2. Conduction describes the process by which heat energy is transmitted through collisions between neighbouring atoms or molecules. (Basically, it happens more readily in solids and liquids, where the particles are closer together)

3. Convection describes the process by which heat is transferred by the movement of a heated fluid such as air or water.

4. Radiation describes the energy that comes from a source and travels through space at the speed of light. This energy has an electric field and a magnetic field associated with it. It has wave-like properties so you could also call radiation “electromagnetic waves”.

Answer:

If I were to be a scientist, I'd be a botanist. A botanist is a scientist who studies plants. For example, they study many different aspects like their genetic, physical structure, and the distribution. They also study the relationship between plants and their different environments.

I would choose to be a botanist, because they help save our plants which are very important. They also help with telling others what exactly causes pollution and possible ways to stop it. Botanist also help with providing human resources like food. Without botanist, we would have a lot less of resources that we use in everyday life.

I can see my life as a botanist in many different ways. I might be put in the chemical based section or I might be put in the analysis of plants. Overall if I were to see myself as any kind of scientist, It would have to be a botanist.

Answer: More atoms and higher temperature mean more thermal energy.

Explanation: The greater the motion of particles, the higher a substance's temperature and thermal energy. A substance's total thermal energy depends on its temperature, number of atoms, and physical state.

Answer:

Builders can minimize their water pollution and maximize their sustainability by following environmental guidelines set by their federal and local governments and by adopting more environmentally sound practices of their own volition.

Explanation:

Many nations have issued sweeping regulations to preserve clean water.

In the United States, for example, the Clean Water Act places special attention on construction activity where disposal sites may interfere with water and wildlife.

In the EU, the Water Framework Directive requires each state to set objectives related to water standards, monitoring sewage, agricultural use and waste among other concerns.

The cold tide may cause the Atlantic currents that bring warmth to Western Europe to slow down. According to NASA's news release, disruptions to the Gulf Stream would have a negative impact on ocean life and the communities that rely on it.

If all the ice on Antarctica, Greenland, and in mountain glaciers around the world melted, sea level would rise by approximately 70 meters. The ocean would engulf all coastal cities. And the land area would be significantly reduced.

The loss of older ice indicates that the Arctic ice cover is thinning. Evidence also suggests that the melt season has lengthened; ice is melting earlier in the year and freezing later than it used to.

Thus,The cold tide could slow the Atlantic currents that bring warmth to Western Europe. Disruptions to the Gulf Stream, according to NASA, would have a negative impact on ocean life and the communities that rely on it.

Explanation:

A penicillin-resistant parent bacteria cell's subsequent generations of bacteria from this parent will be resistant to penicillin. The third option is correct regarding the antibiotics.

The antibiotics are given to kill the bacteria and remove the bacterial infection from the body, but when the bacteria come into contact with the antibiotics for a long time, they will become resistant to them. This is called "antibiotic resistance," as neither the antibiotics nor the bacteria can harm each other now.

Antibiotic resistance is harmful to humans because it necessitates a high dose of antibiotics when infections occurs. This drug has many side effects and can harm the body as well. When the bacteria become resistant to the antibiotic penicillin, all the next generations will be resistant to the antibiotics.

As a result, the correct answer is the third option, which states that future generations will be resistant to penicillin.
