Question

Discuss value of first ionisation enthalpy in same period and why ?​

Answer 1

Answer:

As we move from left to right across a period, the ionisation energy of elements increases. This is due to the decrease in the size of atom across a period. ....... The force of attraction between the nucleus and the electrons increases and hence more energy is required to remove an electron from the Valence shell.
