Question

which of the following elements would you expect to be stable and why A atomic number 2 and atomic weight 4 , B atomic number 11 atomic weight 23 ,C atomic number 13 atomic weight 27​

please answer

Answer 1

Answer:

Element A with atomic number 2 is a stable compound because it has 2 electrons in it's outermost shell which follows the duplet rule... So, it neither needs to gain or lose electrons and doesn't react with any other element, thus being inert.
