1
Q
what is electronegativity
A
the power of an atom to attract bonding electrons towards itself in a covalent bond
2
Q
increases going up the group
A
because bonding electron pairs close to nucleus attracting it
3
Q
increases across the period
A
nuclear charge attracting binding pair is grater
number electron shells shielding bonding pair of electrons from the nucleus is the same
