Alr u see. argon is in group 8 of the periodic table, also known as noble gases. noble gases all have full shells, octect. this means that there is no chance for covalent or ionic bonding, no valence electrons available to bonding.
however, chlorine is in group 7 of the periodic table. this means to obtain a full octect shell, they will have to undergo covalent bonding to form a full octect shell.
hence, argon is more stable compared to chlorine
Answer:
C
Explanation:
Elements in the same groups have similar chemical/physical properties. The reason the answer isn't electron configuration is that if this was the case, there would be no reason for transition metals to exist as they can have a varying amount of electrons in their outer shell.
For example, all alkali metals (Group 1) turn into positive ions when reacting and Halogens (Group 7) all turn into negative ions after reacting.
