Question

which two elements have similar properties and 8 electrons in their outermost shells?

Answer 1

Answer:

Neon and argon have 8 electrons in their outermost shells. The elements which have 8 electrons in the outermost shell or in the valence shell,are known as the noble gases.

Answer 2

Neon and argon have 8 electrons in their outermost shells. The elements which have 8 electrons in the outermost shell or in the valence shell,are known as the noble gases. These gases belong to an extremely stable situation due to the fully filled valence shell and that's why these elements are less reactive.
