The given part of the modern periodic table shows positions of elements a to j

Fill in the blanks by choosing an appropriate option.
Elemetn __i__ resembles sodium in properties and element __ii__ belongs to the same group as nitrogen. The formula of the hydride of g is __iii__. The formula of compound formed between b and c is __iv___while the formula of compound formed between e and g is __v__.

Options

A. `{:(i,ii,iii,iv,v),(h,g,Hg,bc_(2),e_(2)g):}`
B. `{:(i,ii,iii,iv,v),(a,j,H_(2)g,bc_(3),eg):}`
C. `{:(i,ii,iii,iv,v),(b,j,Hg,b_(2)c,eg_(2)):}`
D. `{:(i,ii,iii,iv,v),("h",i,"H g"_(2),bc,eg):}`

Answer

B

Explanation

a is first group element hence, resembles sodium in properties and j is a group 15 element. G is a group 16 element hence, formula of hydride will be `H_(2)g` as valency of g is 2. Valency of element b is 3 (group 13 element) while that of c is 1 (group 17 element) hence, formula of the compound will be `bc_(3)`. Valency of e is 2 while that of g is 2 hence, formula of the compound will be eg.
