(I) Top positions of Lother-Mayer's atomic volume curve are occupied by Alkali metals
(II) Number of elements presents in the fifth period of the periodic table are 32.
(III) `2^(nd)I.P.` of Mg is less than the `2^(nd)` I.P. of Na.
(IV) A p-orbital can take maximum of six electrons.

Text Solution

Verified by Experts

The correct Answer is:
A
`{:((II),5s,4d,5p),("Orbital ",1,5,3):}`
Total orbitals `= 9`
`:.` Total element `= 18`
(III) `Mg^(+) rarr 1s^(2) 2s^(2) 2p^(6) 3s^(1)`
`Na^(+) rarr 1s^(2) 2s^(2)2p^(6)`
`:. Na^(+)` attained inert gas configuration
`:. IE_(2)` of Na is greater than `Mg`.
(IV) p-orbital can have 2 electrons but p-subshell can have 6 electrons.
