The group having isoelectronic species is

A

`O^(2-) , F^(-), Na, Mg^(2+)`

B

`O^(-), F^(-), Na^(+), Mg^(+)`

C

`O^(2-), F^(-), Na^(+), Mg^(2+)`

D

`O^(-), F^(-), Na, Mg`

Text Solution

Verified by Experts

The correct Answer is:
C

`O^(2-) = 8 + 2 = 10 e^(-)1`,
`Na^(+) = 11 - 1 = 10 e^(-), Mg^(2+) = 12 - 2 = 10 e^(-)`
Hence, group (c) contains isoelectronic species.
