Question

A pair of elements which have one unpaired electron in s orbital is​

Answer 1

Answer:

Ga,F,Cl,Br,Sc, and Cu all have one unpaired electron in the ground state.

Answer 2

A pair of elements that have one unpaired electron in s orbital is​ $Ga,F,Cl,Br,Sc, and Cu$.

Explanation:

• An unpaired electron is an electron that occupies an orbital of an atom in a single or in electron pair.
• Every atomic orbital of an atom has three quantum numbers n, l, m, and a spin which has a capacity to contain two electrons (electron pair) with opposite spins.
• n is the principal quantum number,l is the azimuthal quantum number and m is the magnetic quantum number.
• The arrangement of electrons in the orbitals will help to find the arrangements, energy of the different electrons, and the orbital.
• Unpaired electron depends on the number of electrons present in any element.
