chem part 2

Question 1

what are ionic compounds

Answer 1

non-metal and metal formed together

Question 2

how are ionic compounds formed?

Answer 2

1. electron transfer
2. ionic attraction
   3.crystalization

Question 3

what is electron transfer

Answer 3

non metal takes the valence electrons of metal

Question 4

what is ionic attraction

Answer 4

metals turns into cations
nonmetals turn into anions
opposites attract (opposite charges)

Question 5

what is crystallization

Answer 5

pulled together and rearrange into crystal or lattice shape
positive and negative charges are equal so the charge is neutral

Question 6

criss cross method

Answer 6

cross charges from each compound to find subscripts for ionic formula

Question 7

naming ionic compounds

Answer 7

cation name then anion name

Question 8

4 points of ionic compounds

Answer 8

1. always contain cations bonded to anions
2. attracted by ionic bounds
3. ionic bounds are very strong
4. dry ionic compounds are solid at room temperature

Question 9

how are ionic compounds bounded together?

Answer 9

bound between positive and negative particles

Question 10

what are molecular compounds

Answer 10

non-metals combined together

Question 11

how are molecular compounds formed?

Answer 11

non-metals atoms move close together and share valance electrons

Question 12

5 points of molecular compounds

Answer 12

1. non-metals bounded together
2. no metallic atoms or ions
3. bounds holding together called covalent bounds
4. covalent bounds are not strong
5. at room temperature, covalent bounds can be solid, liquid and gas

Question 13

what are covalent bounds

Answer 13

sharing of valence electrons hold two atoms close together

Question 14

ionization

Answer 14

acids when they dissolve in water and separate into ions
