Which one of the following sets of ions represents a collection of isoelectronic species?

A = {x: x ∈ R and x satisfies x2 – 8x + 12 = 0}  2 and 6 are the only solutions of  x2 – 8x + 12 = 0.  ∴ A...

The ions having same number of electrons are called isoelectronic ions. The above order is due to increasing order of effective nuclear charge.

Atoms and ions having the same number of electrons are called isoelectronic species. (i) F– ion has 9 + 1 = 10 electrons. Thus, the species isoelectronic with it will also...

The size of an isoelectronic species increases with a decrease in the nuclear charge (Z). For example, the order of the increasing nuclear charge of F– , Ne, and Na+...

(i) The collection of all months of a year beginning with the letter J is a well-defined collection of objects because one can definitely identify a month that belongs to...

A = {x: x ∈ R and x satisfies x2– 8x + 12 = 0} 2 and 6 are the only solutions of x2 – 8x + 12 = 0. ∴ A...

(c) : n = 3, l = 0 represents 3s orbital n = 3, l = 1 represents 3p orbital n = 3, l = 2 represents 3d orbital n = 4, l...

(b) : Isoelectronic species are the neutral atoms, cations or anions of different elements which have the same number of electrons but different nuclear charge.  Number of electrons in N3– =...

(a) : Isoelectronic species are those which have same number of electrons. K+ = 19 – 1 = 18 ; Ca2+ = 20 – 2 = 18 Sc3+ = 21 – 3...
