Question

Fill in the blanks with appropriate option.
The ability of an atom to attract shared electrons to itself is called $$\underline {\left( {\text{i}} \right)} .$$  It is generally measured on the $$\underline {\left( {{\text{ii}}} \right)} $$  scale. An arbitrary value of $$\underline {\left( {{\text{iii}}} \right)} $$  is assigned to fluorine ( have greatest ability to attract electrons ). It generally $$\underline {\left( {{\text{iv}}} \right)} $$  across a period and $$\underline {\left( {\text{v}} \right)} $$  down a group.

	(i)	(ii)	(iii)	(iv)	(v)

(b)	electro-negativity	Pauling	4.0	increases	decreases
(c)	valency	Mulliken	1.0	decreases	increases
(d)	electron affinity	Mulliken	2.0	increases	increases
