What is first ionization enegy?

Answer 1

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.

Answer 2

The first ionization energy is the energy required to remove the outermost (most loosely held) electron from a neutral atom in its gaseous state. It is a measure of how strongly an atom holds onto its electrons, with higher ionization energies indicating a stronger hold.

Answer 3

Ionization energy is the amount of energy required to remove an valence electron from a gaseous atom.

Answer 4

The amount of energy required to remove and electron from the atom.

Answer 5

An element's first ionization energy is the energy required to remove one electron from each atom of one mole of the element (under standard conditions) when it's in a gaseous form.

Answer 6

ionization energy is the amount of energy that is required to remove the most loosely bounded electron from an isolated gasous atom
