12

electronegativity

ability of atom to attract shared electrons in bond

13

electronegativity of:
metals
nonmetals
transition
noble gases

metals: low electronegativity
nonmetals: high electronegativity
transition: low electronegativity
noble gases: no electronegativity values

14

electronegativity pattern on periodic table

increases going across
decreases going down

15

which element has the highest electronegativity?

fluorine

16

nonpolar covalent bond

equal/almost equal sharing of electrons

17

electronegativity of non polar covalent bonds

0-0.4

18

polar covalent bond

not equal sharing of electrons

19

electronegativity of polar covalent bonds

0.5-1.7

20

what happens to the polarity as the electronegativity difference increases

the polarity increases

21

dipole

polar covalent bond that has a slight charge

22

ionic bond

between metal and nonmetals
