B atom gets hybridised to sort a few equivalent hybrid orbitals directed to three comers of equilateral triangle with B atoms during the centre. Bond angle = one hundred twenty°.
Reply: Let us look at The mix in between atoms of hydrogen HA and HB and eA and eB be their respective electrons.
Loss of an electron from an atom leads to the formation of a cation. A cation is scaled-down than its mother or father atom mainly because it has fomer electrons whilst its nuclear charge remains a similar. By way of example, The atomic radius of sodium (Na) is 186 pm and atomic radius of sodium ion (Na+) = 95 pm.
