bonding of atoms: polar molecules

Question 1

what creates polar molecules?

Answer 1

unequal electron sharing

Question 2

what do atoms in a covalently bonded molecule do?

Answer 2

continually compete for shared electrons

Question 3

electronegativity

Answer 3

the attraction (pull) for shared electrons

Question 4

what atoms pull harder?

Answer 4

more electronegativity atoms pull harder

Question 5

in molecules of only 1 element, the pull toward each atom is what and why?

Answer 5

equal because each atom has the same electronegativity

Question 6

nonpolar covalent bonds

Answer 6

pull toward each atom with same electronegativity

Question 7

polar molecules

Answer 7

unequal electron sharing

Question 8

water has atoms with different electronegativities. oxygen attracts the shared electrons more strongly than hydrogen.. the shared electrons spend more time near oxygen. what type of bond is this?

Answer 8

polar covalent bond

Question 9

in h20, the oxygen atom has a slight negative charge & hydrogens have a slight positive charge. molecules with this unequal distribution of charges are called what?

Answer 9

polar molecules
