Question

Consider the elements in list II. Identify the element on this list that:

Answer 1

Atomic radius increases down the group and decreases from left to right in a period.

Since Sn lies in the 5th period which is more down in period and left in a group than other elements, it will have the largest atomic radius.

Electronegativity is the tendency of an atom to attract the bonding pair of electrons towards itself.

Halogens require only one electron in their valence shell to reach noble gas configuration, so halogens have more electronegativity.

Hence here Cl will have most electronegativity.

Metals are a good conductor of electricity. As we go from left to right in a period, metallic character and hence conductivity decreases.

Since Se has vacant d orbital, it can attain noble gas configuration by sharing up to six electrons.

Hence Se will have the maximum oxidation state of +6.

trifluoroboron is reduced, is formed.

It has the empirical formula of
