Question

Which of the following is not correct for iso-electronic ions? (A) They have the same number of electrons around their nuclei (B) Higher the atomic number, higher will be positive charge in a series of isoelectronic ions of same period (C) Isoelectronic ions have same electric charge (D) An isoelectronic series may have both positively and negatively charged ions

Isoelectronic species have same number of electrons not same isoelectric charge. For example N 3, O 2-, F - are isoelectronic but have different charge.

Q. Which of the following is not correct for iso-electronic ions?

Higher the atomic number, higher will be positive charge in a series of isoelectronic ions of same period

Isoelectronic ions have same electric charge

An isoelectronic series may have both positively and negatively charged ions

Isoelectronic species have same number of electrons not same isoelectric charge. For example $N^{3}, O^{2 -}, F^{-}$ are isoelectronic but have different charge.
