Answer 1

atom with charge

Question 2

Cation

Answer 2

positive charge

Question 3

Anion

Answer 3

negative charge

Question 4

Valence shell

Answer 4

Outer shell of ion

Question 5

ionic compounds

Answer 5

oppositely charges are electrostatically attracted together

Question 6

Polyatomic ions

Answer 6

Ions with more than one ion atom

atoms are strongly bonded together in covalent bond.

Question 7

Covalent bond

Answer 7

sharing valence electrons

Question 8

Ionic bond

Answer 8

ions transfer valence electrons to other ions, this creates difference in charge and bonds

Question 9

Covalently

Answer 9

shared electrons

Question 10

Aqueous solution

Answer 10

ionic compound dissolves in water as ions break apart and attracted to water molecules in ion-dipole bond.
Cations attracted to oxygen
anions attracted to hydrogen
