Question

Explain the general increasing trend in the first

Answer 1

Answer:

The general trend is for ionisation energies to increase across a period. In the whole of period 2, the outer electrons are in 2-level orbitals - 2s or 2p. ... That causes greater attraction between the nucleus and the electrons and so increases the ionisation energies.
