Answer 7

7 VE

Question 8

group 18 valence electrons (VE)

Answer 8

8 VE

Question 9

dot diagram

Answer 9

the symbol for the element surrounded by dots. Each dot represents one valence electron.

Question 10

atomic reaction

Answer 10

atoms give up or receive electrons from other atoms, generally to maintain a stable number (up to 8).

Question 11

chemical bonds

Answer 11

the force of attraction that hold two atoms together. Electrons may be transferred from one atom to another, or they may be shared between the atoms.

Question 12

ionic bonds

Answer 12

An ionic bond is the attraction between two oppositely charged ions. When an atom loses an electron it loses a negative charge and becomes a positive ion. When an atom gains an electron, it gains a negative charge and becomes a negative ion.

Question 13

ion

Answer 13

an atom with an electrical charge - either positive or negative.

Question 14

ions and their charges

Answer 14

can attract different types of elements, forming compounds, such as NaCl.
