Question

class 11 what is ionization energy​

Answer 1

Answer:

Ionization energy is simple terms can be described as a measure of the difficulty in removing an electron from an atom or ion or the tendency of an atom or ion to surrender an electron. The loss of electron usually happens in the ground state of the chemical species.

Explanation:

Answer 2

Answer:

Ionization energy is the quantity of energy that an isolated, gaseous atom in the ground electronic state must absorb to discharge an electron, resulting in a cation. This energy is usually expressed in kJ/mol, or the amount of energy it takes for all the atoms in a mole to lose one electron each.

Explanation:

For Example: Na(g) → Na+(g) + e- I1 = 496 kJ/mol.
