An atom of argon in the ground state tends not to bond with an atom of a different element because the argon atom has 1). more protons than neutrons 2). more neutrons than protons. 3) a total of 2 valence electrons. 4). a total of 8? valence electrons

The correct answer is 4). A total of 8?valence electrons

Explanation:

The argon corresponds to a noble or inert gas, like Helium, and has its complete octet in the last layer.

4. A total of 8 valence electrons

Explanation:

All atom in their ground state is at the actual state of electronic configuration. Argon has 18 number of electrons therefore, representing the electronic configuration using the Spdf  rule is 1s²2s²2p6 3s²3p6 and also the configuration of argon is computed as 2 8 8 . The argon atom has fulfilled the octet rule . The valence/outer electron(8) is fully filled and therefore find it hard to give or accept any electron to form bonding.  

Elements with fully filled octet configuration are known as inert gas or noble gas because they rarely bond with other atom of elements.
