When electrons gain additional energy do they move farther away from the nucleus?

In general, electrons farther from the nucleus will have more energy than electrons closer in. These "outer" electrons are said to be in higher Fermi energy levels, and they have more kinetic energy than the electrons in lower orbitals. Consider that electrons give up energy to "fall into" closer orbitals, and they will, in general, have less energy than the outer electrons. A consequence of the idea that there is less energy binding outer electrons to that nucleus is that it takes less energy to remove that outer electron from an atom. These are the so called ionization energies of the atom's electrons. And when the electron is in a higher orbital, it has a lower ionization energy. It can be removed more easily. As we attempt to remove more electrons from that atom, it takes progressively more and more energy as we move inward removing electrons.

∙ 10y agoThat is quite correct. Energy added to an electron becomes potential energy, in the form of the increased distance from the nucleus. This is very similar to what happens if you lift an object to a higher altitude. The object can fall, and will release energy by falling (for example, water falling through a turbine can generate electricity). Electrons are attracted to the nucleus, so when they move closer to the nucleus, they are in effect falling to a lower energy level. Add energy and they are elevated to a higher energy level. Add enough energy and they leave the atom entirely (in other words, they are ionized).

∙ 14y agoThe kinetic energy of electrons is higher in orbitals near the nucleus but potential energy of electrons is higher in orbitals far away from nucleus.

∙ 14y agoNo, as electrons tend to move away from the nucleus there energy increases
Wiki User
∙ 12y agoNo, just the opposite. The farther from the nucleus, the greater energy it has.
An electron with enough energy can break free of the nucleus and sail away
on its own.

Electrons farther from the nucleus are said to be of?
"higher energy"
Why ionization energy decreases down the group and increases along a period?
Going down a group, the number of valence electrons remains the same, but these electrons get farther and farther away from the nucleus. Thus, they are not as tightly held and the ionization energy decreases. Moving from left to right along a period, the electrons are the same distance from the nucleus, but the number of protons are increasing in the nucleus, thus holding those electrons more tightly. Thus, the ionization energy increases.
The valence electrons of which element has the highest energy hydrogen lithium sodium or potassium?
To determine this look at the periodic table. The larger the atom, the farther its valence electrons are from the nucleus. Therefore, potassium's valence electrons have the highest energy.
How does the energy of an electron change when the elctron moves closer to the nucleus?
the electrons moving closer to the nucleus have lower energy level.why?AnswerWhen atoms absorb energy, electrons move into higher energy levels, and these electrons lose energy by emitting light when they return to lower energy levels.It's like a sea saw, you go up, you get energy, go back down, lose it.please recommend me :D
How are electrons arranged in the atom?
Electrons are arranged around the atomic nucleus forming the electron clouds.
Electrons farther from the nucleus are said to be of what energy?
higher energy
Electrons farther from the nucleus are said to be of?
"higher energy"
Why does radius increase if you go down a group?
Because as you go down a group, with each additional period, an additional energy level is added. Each additional energy level is farther from the nucleus than the previous energy level.
Which has more potential energy an electron close to an atomic nucleus or one far from an atomic nucleus?
In general, electrons farther from the nucleus will have more energy than electrons closer in.
When you move down a family of elements why the size increases?
It is because when you move down, the number of electrons increases. When the number of electrons increases, it calls for more energy levels to fit these electrons.With each additional period, an additional energy level is occupied. This additional energy level is farther from the nucleus than the previous energy level, so the atoms increase in size.
The farther an energy level is from the nucleus the bigger is its what?
You must be thinking of electrons in shells surrounding the nucleus. The quantity getting bigger is therefore the diameter of the electrons orbit.
Which factor contributes to decreases in ionization energy withing a group in theperiodic table as the atomic number increases?
Ionization energy decreases down a group because with each additional period, there is an additional energy level, so the outermost electrons are farther away from the positive charge of the nucleus, so they are not held as tightly. The further away the valence electrons are from the nucleus, the less energy is required to remove an electron, so the ionization energy decreases.
The farther an electron is from the nucleus the?
The farther an electron is from the nucleus, the greater its energy.

Why do you suppose that an energy level close to the nucleus can hold fewer electrons than one farther away from the nucleus?
it has to do with quantum numbers N,L, and M
The valence electrons of which element has the highest energy hydrogen lithium sodium or potassium?
To determine this look at the periodic table. The larger the atom, the farther its valence electrons are from the nucleus. Therefore, potassium's valence electrons have the highest energy.
Why do element in the third period have lower ionization energies than elements in the second period?
With each additional period, there is an additional energy level, which means that the outermost electrons are farther away from the nucleus of the atom. This means that the attractive force of the positively charged nucleus is less, so it takes less energy to remove an electron from an atom in the third energy level than it does from an atom in the second energy level. Therefore, the elements in the third period have lower ionization energies than elements in the second period.
