Elements X and Y have 5 and 7 valence electrons.
a) Predict the nature of elements - whether metals or non metals.
b) What is the nature of the molecule when these combine?
c) Draw the structure of the molecule.
d) What is the valency of X in the molecule?
e) Predict its physical state.
1. They both are non-metals.
2. They both form covalent bonds.
3. XY3 is the molecule so formed.
4. Valency of X is 3 as it required three electrons to complete its octet.
5. It is gaseous in nature.
