The size and shape of an electron cloud are most closely related to the electron's what?
It is mostly related to the energy of the electron.
What do you call the energy involved when an atom loses an electron?
The amount of energy required to remove an electron form an at is the ionization energy.
The rest mass energy of an electron positron pair is?
Twice the mass of the electron, since the positron has the same mass of the electron. Or the equivalent, in energy units.An electron has a mass or energy of 511 keV.
When an electron is ejected from the surface what type of energy does the electron possess?
It is moving, so it has kinetic energy.
Principal energy level 1 of an atom contains an electron with the lowest energy why?
level one electron contain more energy
Which atom requires the least energy for the removal of the most loosely bound electron a.Sn b.Sr c.Be d.Br?
C. Be. Beryllium.
What are ionization's?
the removal of electron or ion
Why is the 2nd ionisation energy of Cr higher and not lower than of Mn?
The electron configuration of a neutral chromium atom is [Ar]3d54s1. The electron configuration for manganese is [Ar]3d54s2. The first electron removed from a chromium atom is the single 4s electron, leaving the electron configuration [Ar]3d5. The first electron removed from a magnesium atom is one of the 4s2 electrons, leaving the electron configuration [Ar]3d54s1. Removal of a second electron from a chromium atom involves the removal of one of the 3d electrons, leaving a configuration of [Ar]3d4, which is not a very stable configuration, and requires more energy to achieve. Removal of a second electron from a magnesium atom involves the removal of the second 4s electron, leaving a configuration of [Ar]3d5, which is more stable and requires less energy to achieve.
Why formation of di and tri-negaive ions is endothermic process?
when an electron is added to an atom, uninegative ion is formed and enrgy is released. the addition of one more electron is difficult because negative charge or electronic cloud repels it strongly, to overcome this repelsion an amount of energy is needed, which is obtained by surroundings so its an endothermic reaction.
The energy of an electron varies depending upon which energy level that electron occupies.?
Yes, the energy of an electron does vary depending on which energy level it occupies.
Why the addition of two electrons or removal of one electron requires more energy in oxygen atom?
Type your answer here... when adding an electrons to oxygen it needs more energy in electron affinity in order to attract electrons from other atoms to be stable.and we know that oxygen is in short of two electrons.so in the other hand when an electron is removed from oxygen it will be unstable and will be needing more ionization energy to be able to remove an electron to it.Thus mean indeed when adding or removing electrons for oxygen it requires energy.
How does the electron's energy change as the orbit of the electron increases?
The farther an electron is from the nucleus of an atom, the more energy it has.
What information does the first quantum number of an electron give?
The energy level the electron is in
The energy required to remove an electron from a neutral atom is the atom's?
Ionization Energy or electron energy
The size and shape of an electron cloud are most closely related to the electron's what?
It is mostly related to the energy of the electron.
Electron X can change to a higher energy level or a lower energy level Which statement is true of electron X?
Electron X absorbs energy when it changes to a higher energy level. Electron X absorbs energy when it changes to a higher energy level. It takes energy to do that.
What can happenn if an electron moves to a higher energy level?
the electron will gain energy
