Q.1 In period 2, element 'A' is to the right of element 'B'.
[5]
1. The element'A' would probably have a
- [smaller/larger) atomic size than 'B'.
2. The element 'B' would probably have
[lower/higher] ionisation potential than 'A'.
3. The element'A' would have
[lesser/higher) electron affinity than 'B'.
4. Nuclear charge of element 'B' would be
[less/more) than element'A'.
5. If an element 'C' had a low electronegativity and ionisation potential it would have more tendency to
[gain/lose) electrons.
