Why is boron has lower ionization energy than berylium?

Boron has a lower ionization energy than beryllium because boron has an extra electron in a higher energy level orbital, making it easier to remove. This higher energy level allows the electron to be further from the nucleus, experiencing less attraction, resulting in lower ionization energy.

Why is the ionisation energy of boron less than that of beryllium?

The ionization energy of boron is lower than that of beryllium because in boron, the electron being removed is farther from the nucleus, experiencing less of the nuclear charge, making it easier to remove. Additionally, boron's electron configuration involves removing an electron from a higher energy level, which requires less energy compared to removing an electron from a lower energy level in beryllium.
