Question

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 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​

Answer 1

Answer:

Explanation:

Isoelectronic species are elements or ions that have the same or an equal number of electrons. Isoelectronic species have the same number of electrons, they are different in their physical and chemical properties
