When a metal reacts with a nonmetal, the metal will...

a) lose electrons and form a positive ion

b) gain electrons and form a negative ion

c) gain protons and form a negative ion

d) lose protons and form a positive ion

Answer : The correct option is, (a) lose electrons and form a positive ion

Explanation :

Metals : These are the elements that easily loose electrons and forms cations.

They require less energy to loose electrons because electrons are loosely bound to the nucleus.

Non-metals : These are the elements that easily gain electrons to form an anion.

They require more energy to loose electrons because the electrons are tightly bound to the nucleus.

As per question, when a metal reacts with a nonmetal, the metal will lose electrons and form a positive ion and non-metal gain electrons and form a negative ion.

Hence, the correct option is, (a)

the electronic configuration of an atom with eight electrons is 1s²2s²2p⁴. the orbital diagrams are shown in the figure.

as per the hunds rule:

1. electrons tend to avoid being in the same orbital as per as practicable.

2. electrons in different orbitals of the same energy will have their spin parallel.

this can be illustrated from the multiplicity of the orbitals of the atom. as there are four electrons in the p orbital and p orbital has 3 sub-shells. the electrons can be fed in different ways as shown in the figure but the correct orbital diagram will be as per the hunds rule.
