Element X is a metal with a valency 2, Y is 3 non- metal with a valency 3.
1) Write an equation to show how Y from an ion.
2) If Y is a diatomic gas, write an equation for the direct combination of X and Y to form a compound.
Explain the following:
Halogens have a high electron affinity.
A, B, C are three elements in which B is an inert gas other than helium.With this information complete the following table.
| Element | Atomic number | No. of electrons in the valence shell | Group to which the element belongs |
| A | Z - 1 | ||
| B | Z | ||
| C | Z + 1 |
Also, explain the following : Electron affinity of element A is more than that that of element C.
