The energy needed to remove an electron from an atom (in the gaseous state) is called the IONIZATION ENERGY.
Ionization Energy or electron energy
The electron
ionization energy
First ionization energy is the energy required to remove the first outermost electron from an atom. The second ionization energy is the energy required to remove the next available electron, and is greater than the first IE. The third IE is that energy needed to remove the third electron, and is greater the the second IE.
Electron affinity is the amount of energy required to remove an electron from an atom. Or an energy released by adding an electron to a gaseous atom ( ie, negative quantity). In this case, if an element has a negative Electron Affinity, its indicating that this element is stable than the neutral ones.
Ionization Energy or electron energy
Ionization energy is more commonly used to remove the topmost electron in the atom very important information if you are getting ready for a test.
The energy required to remove an electron from an atom
The electron
The amount of energy required to remove an electron form an at is the ionization energy.
The ionization energy, expressed in kJ/mol.
ionization energy
How much energy is required to move the electron of the hydrogen atom from the 1s to the 2s orbital
The energy required to remove completely an electron from its atom.
First ionization energy is the energy required to remove the first outermost electron from an atom. The second ionization energy is the energy required to remove the next available electron, and is greater than the first IE. The third IE is that energy needed to remove the third electron, and is greater the the second IE.
it is the energy required for a mole of atom to loose a mole of electron.
Briefly, it is the energy required to completely remove a valence (outer shell) electron from its atom when forming an ionic bond.See related links below for more info
