Which of the following would you expect to form an ionic bond when combined? (2 points) select one: a. si and o b. k and ti c. h and o d. li and f

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.

c. 75.7

i think that is the right
