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.
What else can I help you with?
Electrons farther from the nucleus are said to be of?
Electrons farther from the nucleus are said to be of higher energy levels or higher orbitals. This means they have more energy and are less tightly bound to the nucleus compared to electrons closer to the nucleus.
How does the energy of core electrons compare with the energy of valence electrons?
The energy of the valence electrons is greater than the energy of the core electrons.
What statement accurately represents the arrangement of electrons in bohr's?
In Bohr's model, electrons orbit the nucleus in specific energy levels or shells. Electrons can only exist in these quantized energy levels, and they move between them by absorbing or emitting energy. The energy of an electron is lower when it is closer to the nucleus and higher when it is farther away.
Which electrons in oxygen have more energy those in the first level or those in the second?
More energy have the electrons in the second level of energy.
Which statement describes the relative energy of electrons in the shells of a calcium atom?
Electrons in higher energy shells of a calcium atom are farther from the nucleus and have more energy than electrons in lower energy shells. This is because as the energy level of a shell increases, the distance from the nucleus also increases, resulting in higher potential energy for the electrons.
Is the electrons farther from the nucleus?
Yes, electrons in higher energy levels are farther from the nucleus compared to electrons in lower energy levels. This is due to the increased energy of electrons in higher energy levels.
Electrons farther from the nucleus are said to be of?
Electrons farther from the nucleus are said to be of higher energy levels or higher orbitals. This means they have more energy and are less tightly bound to the nucleus compared to electrons closer to the nucleus.
Electrons farther from the nucleus are said to be of what energy?
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.
How does the electron's energy change as the orbit of the electron increases?
As the orbit of the electron increases, the electron's energy also increases. Electrons in higher energy orbits are farther from the nucleus and have more potential energy. Conversely, electrons in lower energy orbits are closer to the nucleus and have less energy.
How does the energy of core electrons compare with the energy of valence electrons?
The energy of the valence electrons is greater than the energy of the core electrons.
Which has more potential energy an electron close to an atomic nucleus or one far from an atomic nucleus?
An electron far from an atomic nucleus has more potential energy compared to one close to the nucleus. This is because the farther the electron is from the nucleus, the higher its potential energy due to the increased distance from the attraction of the positively charged nucleus.
Why do you suppose that an energy level close to the nucleus can hold fewer electrons than one farther away from the nucleus?
Energy levels close to the nucleus have lower energy, which means electrons are more tightly bound and experience stronger electrostatic attraction to the nucleus. This results in a limited capacity for electrons at lower energy levels. As electrons move to higher energy levels, they are farther from the nucleus and experience weaker attraction, allowing for higher electron capacity.
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.
How does the energy of core electrons compare with that of valence electrons?
Core electrons have lower energy levels than valence electrons. Core electrons are closer to the nucleus and are more tightly bound, while valence electrons are in the outermost energy level and have higher energy due to being farther from the nucleus.
In an atom an electron that is close to the nucleus is on the highest enegry level?
No. The greater distance from the nucleus the more energy an electron has.
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.
