Question

Three elements with filled outermost shells. (Name it)

Answer 1

(a) Lithium (Li), sodium (Na), and potassium (K) have a single electron in their outermost shells. (b) Magnesium (Mg) and calcium (Ca) have two electrons in their outermost shells. (c) Neon (Ne), argon (Ar), and xenon (Xe) have filled outermost shells.

Answer 2

Answer:

Three elements with filled outermost shells include; Neon, Argon and Xenon

Explanation:

These elements are part of the group 8 elements also known as the noble gases. The noble gases have complete or filled outermost shells with 8 valence electrons.

The elements in this group are quite stable due to the filled valence electrons. The elements in this group rarely react with other elements to form chemical compounds.

Other elements in this group 8 with complete orbitals include:

   Neon

   Argon

   Xenon

   Krypton

   Radon

   Helium
