Covalent bonding 2

What is electronegativity

The ability to attract electrons towards itself in a covalent bond

What happens to electronegativity across a peroid

increases

What happens to electronegativity down a group

decreases

What do chemists to measue electronegativity

Pauling scale

The higher the number of the Pauling scale what does that mean

The higher the number, the more electronegative the atom. 

Hydrogen has similar electronegativity to what element and why

C because Hydrogen has no shielding

Most electronegative element is

F

What makes a bond polar

if difference in Pauling’s scale value > 0.5

What makes a bond more polar

The larger the difference in electronegativity

what bonding is the Compounds with a difference in electronegativity larger than 2.5 in compound

ioncally

what bonding is the Compounds with a difference in electronegativity smaller than 2.5 in compound

covalently

Elements with electronegativities larger than or equal to 2.12.12.1 tend to bond in elements

covalently

Elements with electronegativities smaller than or equal to 1.51.51.5 tend to bond
