Bond Polarity

Question 1

Electronegativity

Answer 1

The power of an atom to pull the electron density of a covalent bond towards itself

Question 2

Most electronegative atoms - 3 points

Answer 2

N-itrogen
O-xygen
F-lourine

Question 3

Electronegativity depends on… -2 points

Answer 3

• atomic radius -> size of an atom= the closer the electron to the nucleus, the stronger the force pulling the electrons = higher electronegativity
• nuclear charge -> greater no. of protons = stronger attraction to greater attraction to electrons = higher electronegativity

Question 4

Elecronegativity ________ across the period, as the number of __________ increases

Answer 4

• increases
• protons

Question 5

Polarity

Answer 5

the unequal sharing of electrons in a bond

Question 6

Non- polar bond

Answer 6

equal sharing of elctrons

Question 7

Assymetrical shape - polar or non polar?

Answer 7

polar

Question 8

Symmetrical shape - polar or non polar?

Answer 8

non - polar
