The electron arrangement of three atoms X, Y and Z is (2, 8, 8, 1), (2

1.	The electron arrangement of three atoms X, Y and Z is (2, 8, 8, 1), (2, 8, 6) and (2, 8, 18, 7) respectively. (1) What will be the formula of a compound formed between X and Y? (11) State the type of bonding seen in a molecule of Z Which element is likely to be a bad conductor of electricity - X or Y?
Answer» Answer: 1) X2Y, 2) Covalent bonding, Y is the bad of conductor of electricity because it is a non-metal. Explanation: ● 1) The ELEMENT X belongs to GROUP - 1 of the periodic table. It contains 1 valance electron. The element Y belongs to group - 16 of the periodic table and contains 6 valance electrons. The element Y requires 2 more electrons from X to complete its OCTET. So, the formula of compound of X and Y is X2Y. ●2) Z is a HALOGEN . Its molecule possesses covalent bonding because of mutual sharing of electrons between two Z atoms.

Answer»

Answer:

1) X2Y, 2) Covalent bonding, Y is the bad of conductor of electricity because it is a non-metal.

Explanation:

● 1) The ELEMENT X belongs to GROUP - 1 of the periodic table. It contains 1 valance electron. The element Y belongs to group - 16 of the periodic table and contains 6 valance electrons. The element Y requires 2 more electrons from X to complete its OCTET. So, the formula of compound of X and Y is X2Y. ●2) Z is a HALOGEN . Its molecule possesses covalent bonding because of mutual sharing of electrons between two Z atoms.
