Which of the following is not correct for isoelectronic ions?
1 They have the same number of electrons around their nuclei
2 Higher the atomic number, higher will be the positive charge in a series of isoelectronic ions of same period
3 Isoelectronic ions have same electric charge
4 An isoelectronic series may have both positively and negatively charged ions
Explanation:
Isoelectronic species have same number of electrons but not same isoelectric charge. For example \(\mathrm{N}^{3-}, \mathrm{O}^{2-}, \mathrm{F}^{-}, \mathrm{Na}^{+}, \mathrm{Mg}^{+2}, \mathrm{Al}^{+3}\) are isoelectronic but have different charges.

Paramagnetism is common in
1 p-block elements
2 d-block elements
3 s-block elements
4 f-block elements.
Explanation:
Due to variable oxidation states and presence of unpaired electrons d-block elements show paramagnetism most commonly.
