How many dots should be placed around argon in a dot diagram? A) 2 C) 6 D) 8

The number of dots that should be placed around argon in a dot diagram is : ( D )  8

Argon is a noble gas ( inert gas ) just like helium and neon and they have their outer most shell completely filled with its electrons ( 8 valence electrons ), which makes them non-reactive with any other element or compound.

Every valence electron in the Lewis structure of an atom is represented with a dot therefore the 8 valence electrons in Argon will be represented with 8 dots.

Hence we can conclude that the number of dots that should be placed around Argon in a dot diagram is 8.

8

Explanation:

You add a dot for each valence electron. Argon is a noble gas meaning it has 8 valence electrons.
