Question

Questions 1.1 to 1.4 are based on the Table A. Study this table and answer the following questions.

(4)

1.1 In the Table A, find out which element’s atom has to gain or lose the highest number of electrons to

complete its octet?

1.2 Nitrogen atom’s outermost shell has 5 electrons. Then how is its valency 3, not 5?

1.3 Which is more reactive among Oxygen and Fluorine?

1.4 In what ways can an atom achieve an octet?​

Answer 1

Answer:

1.1 From Table A, it appears that chlorine (Cl) has to gain or lose the highest number of electrons (7) to complete its octet.

1.2 Nitrogen atom's outermost shell has 5 electrons, but it still has an incomplete octet, so it can gain or lose 3 electrons to complete its octet, which is its valency.

1.3 Oxygen is less reactive than Fluorine.

1.4 An atom can achieve an octet by gaining or losing electrons, or by sharing electrons through chemical bonding with other atoms.
