The group having isoelectronic species is

1.	The group having isoelectronic species is
Answer» `O^(2-) , F^(-), Na, Mg^(2+)` `O^(-), F^(-), Na^(+), Mg^(+)` `O^(2-), F^(-), Na^(+), Mg^(2+)` `O^(-), F^(-), Na, Mg` Solution :`O^(2-) = 8 + 2 = 10 e^(-)1`, `Na^(+) = 11 - 1 = 10 e^(-), Mg^(2+) = 12 - 2 = 10 e^(-)` Hence, GROUP (C) contains isoelectronic species.
