3.3 electron configuration and sizes

Question 1

define covalent

Answer 1

reaction between two nonmetals, electron sharing ensures complete valence electron configuration of both atoms; both nonmetals obtain a noble gas electron configuration

Question 2

define ionic

Answer 2

reaction btwn a representative-group metal and a nonmetal, a binary ionic compound is formed; ions are formed in such a way that both ions achieve noble gas configuration

Question 3

what is attraction btwn positive and negative ion’s maximum caused by?

Answer 3

close proximity of the positive and negative ions, unlike those of compounds in the gaseous phase.

Question 4

large attractive forces tend to…

Answer 4

increase the stability of a compound

Question 5

chemical compounds are always…

Answer 5

electrically neutral

Question 6

the structure and stability of ionic solids is influenced by…

Answer 6

ion size

Question 7

how is ion size determined?

Answer 7

by measuring the distance between ion centers

Question 8

what are the two factors that influence ionic size?

Answer 8

size of parent ion
position on the periodic table
