Atoms form chemical bonds to satisfy what rule

The rule is called as Octet Rule.

Explanation:

Chemical bond: the attractive force which holds the atoms together in a molecule. Except noble gases He,Ne,Ar,Kr and Rn all other atoms  have less than 8 electrons in its outer shell and unstable.

In order to attain stability Atoms loses or gains or shares electron to get 8 electrons in its outer shell which is called noble gas configuration.

“Octa” means 8.

The respectable gases are the main arrangement of components that have 8 electrons in their furthest shells and that is the reason they are steady and lifeless. The octet principles express that a component must have 8 electrons in its furthest shell as to be steady.

explanation:

answer:

technetium is the most reactive. this is followed by silver. the least reactive out of these three elements is strontium.
