names and formulas for ionic compounds

Question 1

ionic compounds usually consist of:

Answer 1

cation and anion
metal and nonmetal
polyatomic cation and polyatomic anion
or oxyanion

Question 2

polyatiomic ions

Answer 2

ions that are made up of more than one atom

Question 3

monoatomic ions

Answer 3

one atom ion

Question 4

formula unit

Answer 4

the chemical formula for an ionic compound ; represent the simplest ratio of the ions involved

Question 5

rules for writing chemical formulas:

Answer 5

1: write the symbol
2: oxidization number
3:simplify
4: cross

Question 6

oxidization number

Answer 6

the charge of the ion , the number of electrons gained or lost ; equals the net charge of the ion

Question 7

NH4^+

Answer 7

ammonium cation

Question 8

SO4^-2

Answer 8

sulfate anion

Question 9

NO3^-

Answer 9

nitrate anion

Question 10

NO2^-

Answer 10

nitrite anion

Question 11

OH^-

Answer 11

hydroxide

Question 12

CO3^-2

Answer 12

carbonate

Question 13

PO4^-3

Answer 13

phosphate

Question 14

true or false most transition metals have more than one possible ionic charge

Answer 14

true

Question 15

what does the oxidization number of an element in an ionic compound equal to?

Answer 15

the number of atoms transferred from one atom to another

Question 16

rules for writing chemical formulas for ionic compounds

Answer 16

1:the symbol of the cation is written first then the anion
2:subscripts represent the number of ions of each element in an ionic compound ; if the sub script is 1 then its not written
3:when adding the oxidation umber of each ion multiplied by the number of the ions in a formula unit the total net charge must be zero

Question 17

naming ionic compounds

Answer 17

1:name cation followed by the anion
2:for monatomic cations use its name and anion use the root then ide
3:the oxidization level is written in roman number in parentheses after the name of cation
4:use the name of the polyatomic ion in place of cation or anion
