Bonding

Question 1

Coordinate bonding/dative bonding

Answer 1

is a covalent bond (a shared pair of electrons) in which both electrons come from the same atom

Question 2

Electron deficient

Answer 2

the atom that accepts the electron pair is an atom that does not have a filled outer level of atoms

Question 3

Lone pair

Answer 3

atom that donates the electrons has a pair of electrons that is not being used in a bond

Question 4

Electronegativity

Answer 4

is a measure of the tendency of an atom to attract a bonding pair of electrons

Question 5

Factors affecting electronegativty

Answer 5

-nucleur charge
-distance between the nucleus and outermost electrons
-shielding
-smaller the atom, closer the nucleus is to the shared electrons- greater the electronegativity
-larger the nuclear charge, greater the electronegativity

Question 6

As you go across a period, electronegativity

Answer 6

increases

Question 7

Electronegativity increases across a period because

Answer 7

number of charges on the nucleus increases, that attracts the bonding pair of electrons more strongly.

Question 8

As you go down the group, electronegativity

Answer 8

decreases

Question 9

As you go down the group, electronegativity decreases because

Answer 9

the bonding pair of electrons is increasingly distant from the attraction of the nucleus

Question 10

A compound containing elements of similar electronegativity and a small electronegativity difference will be purely

Answer 10

covalent

Question 11

A compound containing elements of very different electronegativity and a very large electronegativity difference will be

Answer 11

ionic

Question 12

Polarity meaning

Answer 12

unequal sharing of electrons in a bond
