Interpretation:
The noble gas with which the anion
Concept introduction:
Isoelectronic means the total number of electrons of one element is equal to another element. Isoelectronic species can also be expressed in terms of electronic configuration by equating there general electronic configuration of the outermost shell.

- Which of the following is isoelectronic pair? (i) ICl2, ClO2 (ii) BrO2– , BrF2+ (iii) ClO2, BrF (iv) CN–, O3arrow_forwardAnswer true or false. (a) The octet rule refers to the chemical bonding patterns of the first eight elements of the Periodic Table. (b) The octet rule refers to the tendency of certain elements to react in such a way that they achieve an outer shell of eight valence electrons. (c) In gaining electrons, an atom becomes a positively charged ion called a cation. (d) When an atom forms an ion, only the number of valence electrons changes; the number of protons and neutrons in the nucleus does not change. (e) In forming ions, Group 2A elements typically lose two electrons to become cations with a charge of 12. (f) In forming an ion, a sodium atom (1s22s22p63s1) completes its valence shell by adding one electron to fill its 3s shell (1s22s22p63s2). (g) The elements of Group 6A typically react by ac- cepting two electrons to become anions with a charge of 22. (h) With the exception of hydrogen, the octet rule applies to all elements in periods 1, 2, and 3.
