Question

Which of the following elements are characterized by having full outermost s and p

Answer 1

Answer:

Group 8A

Explanation:

Group 8A elements are characterized by having full outermost s and p orbitals. These elements are also known as the noble gases or inert gases. They occupy the last group on the periodic table.

• They are known to have an outer shell configuration of ns² np⁶
• The configuration reveals that atoms of all the elements have completely filled orbitals in their outer shell sublevels.
• This accounts for the non-reactivity of elements in this group.
• Most of the elements in the group have high ionization energy and very low electron affinity values.

Some of the elements in this group are Neon, Argon, Krypton, Xenon, and Radon.
