Question

Define ionization enthalpy; arrange elements of gr 1 and gr+ period elements according to increasing ionisation enthalpy?​

Answer 1

Explanation:

In physics and chemistry, ionization energy or ionisation energy, is the minimum amount of energy required to remove the most loosely bound electron of an isolated neutral gaseous atom or molecule.

Answer 2

Answer:

The energy required to remove an electron from a neutral isolated gaseous atom and convert it into a positively charged gaseous ion is called ionization potential.or ionization energy.

The ionization energy tends to increase as one moves from left to right across a period.
