`K^+` and `Ca^(2+)` are isoelectronic with Argon.
Out of `Na^+` and Na which has smaller size and why?

K^+ and Ca^(2+) are isoelectronic with Argon. Explain what is isoelectronic ions.

Ions having same number of electrons are called isoelectronic ions. Out of Na^+ and Ne which has higher ionisation enthalpy. Explain why?

Assertion: Na^(+) and Al^(3+) are isoelectronic but the magnitude of the ionic radius of Al^(3+) is less than that of Na^(+) Reason: The magnitude of effective nuclear charge of the outer shell electrons in Al^(3+) is greater than in Na^(+)

Ions having same number of electrons are called isoelectronic ions. Give example of 2 cations and 2 anions which are isoelectronic with argon.

Periodic table in a chart in which elements having similar chemical and physical properties are grouped together. Out of Fe^(2+) and Fe^(3+) ions which is smaller in size? Explain.

The size of iso electronic species F^- , Ne and Na^+ is affected by

A l^(3+)' is not isoelectronic with (1)Ne (2)Na^+ (3)F^- (4)Ca^2+

Explain why Na is less reactive than K?

The size of iso electronic species F-Ne and Na^+ is affected by
