Question

Among the elements of the main group,the first ionization increases?

Answer 1

Across the period

Explanation:

Among the element of the main group, the first ionization energy increases across the period.

• The energy required to remove an electron from an atom is called ionization energy.
• The first ionization energy is the energy needed to remove the most loosely bound electron of an atom in the gas phase.
• The ionization energy measures the readiness of an atom to lose an electron.

The magnitude of the ionization energy depends on nuclear charge, atomic radius, sublevel accomodating the electron and the special stability of filled and half-filled sublevels.

Generally, ionization energy increases progressively from left to right due to the decreasing atomic radii.

Down a group, it decreases because atomic radii is increasing
