Question

How will the tendency to gain electrons change as we go from left to right across a period? Why? [2 MARKS]

Answer 1

Each point: 1 Mark

1. On moving from left to right across a period, metallic character decreases and non-metallic character increases.
2. Since metals tend to lose electrons and non-metals tend to gain electrons, the tendency to gain electrons increases as we move from left to right across a period.
