Electrons are shared- giving each atom a share of 8 electrons. Note that this "rule" does not work for hydrogen as only two electrons need to be shared to give each H atom the electronic configuration of He, helium.
It makes two covalent bonds which completes its octet.
Ionic Bonds are when electrons are exchanged to satisfy the octet of each element reacting. Covalent Bonds are when two atoms SHARE their electrons to satisfy the octet rule.
look for it on the chemistry book, and don't be lazy!Covalent bonding is all about "sharing electrons" so the two elements share electrons (which forms a covalent bond) in order to complete or help complete their octet.
no it does not follow octet rule
yes
Sodium would LOSE 1 electron to satisfy the octet rule.
Boron And Berylium
One
Boron will form the covalent bonds based on the octet rule.
true
Strontium is part of Group IIA, which means it loses 2 valence electrons to satisfy the rule. Sr2+.
The number of Covalent Bonds is equal to eight minus the group number.
