Whats the maximum number of electrons that can fit into the outer shell of boron? Like silicon has 4 electrons in the outer shell but the maximum it can hold is 8 electrons so whats the maximum number of electrons that can fit into the outer shell of boron which has 3 electrons but can it hold more in the outershell?
Boron can conceivably fit a maximum of 8 electrons in its outer shell. This could be achieved through boron covalently bonding with a non-metal (as boron is a metalloid).
It is in the 2nd period (row) of the periodic table, hence has 2 'shells', following the 2n2 pattern for maximum amount of outer shell electrons (where 'n' is the amount of 'shells' the element has).
