`Na^(+),K^+, Mg^(+), Ca^(2+), S^(2-), Ar`

Text Solution

AI Generated Solution

To determine which of the given species are isoelectronic (i.e., have the same number of electrons), we will calculate the number of electrons for each species. ### Step-by-Step Solution: 1. **Calculate the number of electrons in Na⁺ (Sodium ion)**: - Atomic number of Na = 11 - Na⁺ has lost 1 electron. - Number of electrons = Atomic number - Charge = 11 - 1 = **10 electrons**. ...
