Are Ar and Na isoelectronic?

Yes, argon (Ar) and sodium (Na) are isoelectronic. Isoelectronic species have the same number of electrons. Argon has 18 electrons, while neutral sodium has 11 electrons, but when sodium loses one electron to form the Na⁺ ion, it also has 10 electrons, making it isoelectronic with neon (Ne), not argon. Therefore, Ar and Na are not isoelectronic.


Which neutral atom is isoelectronic with each what ions F Ca2 P3 K Pb2?

An atom is isoelectronic with another if they have the same number of electrons. The neutral atom that is isoelectronic with F (9 electrons) is Ne (neon). For Ca²⁺ (20 electrons), the isoelectronic atom is Ar (argon). P³⁻ (18 electrons) is isoelectronic with Ar as well, while K⁺ (18 electrons) is also isoelectronic with Ar. Pb²⁺ (78 electrons) is isoelectronic with the neutral atom Xe (xenon).

Cl & K ions are isoelectronic with Ar.


S2- Cl1- and Ca2 plus are all with Ar?

They have the same electron configuration as argon, which means they are isoelectronic with argon.


Is K isoelectronic?

Potassium (K) is not isoelectronic with any other element in its neutral state. However, when it loses one electron to form a potassium ion (K⁺), it becomes isoelectronic with argon (Ar), as both have the same electron configuration of 18 electrons. Isoelectronic species have the same number of electrons and similar electronic structures, which in this case occurs when K loses an electron.


S2- Cl1- K1 plus and Ca2 plus are all with Ar?

They have the same electron configuration as argon, which means they are isoelectronic with argon.


Isoelectronic with another element what does this mean?

Two elements are isoelectronic if they have the same number of electrons. This means they will have similar chemical properties and can form similar types of bonds. An example is neon (Ne) being isoelectronic with sodium (Na+).


Why is argon isoelectronic with Ti4 plus?

Argon has 18 electrons, while Ti4+ has 22 electrons. When Ti loses 4 electrons to form Ti4+, it loses the outer 4s2 and 3d2 electrons, leaving an electron configuration of [Ar] for both species, making them isoelectronic.
