⭐(fix)Nomenclature

Question 1

Nomenclature of ionic compounds

Answer 1

Always in empirical (simplest whole # ratios)

Question 2

What law is used when atoms in an ionic compound have equal/opposite charges?

Answer 2

Law of conservation of charge/energy

Question 3

Binary ionics

Answer 3

METAL+NONMETAL
2 different elements, end in -ide
Ex: K3P potassium phosphide

Question 4

Ternary ionics

Answer 4

METAL+POLYATOMIC, 3/+ different elements (look at table e! Usually ends in ate/ite sometimes ide)
Ex: Mg(ClO2)2 magnesium chlorite

Question 5

How do u know how many atoms should be in an ionic compound? Ex: Ba+2(Po4)-3

Answer 5

Multiply by a quantity so the charges cancel out.

Ex: Ba(3•2) plus (Po4)(-3•2)=6-6=0

Question 6

Stock system

Answer 6

Roman numerals used to represent the value of oxidation # for a cation (metal) with MULTIPLE oxidation #’s,
Ionic Ex: Fe(+2/+3)Cl3(-1)=Choose Fe +3, Iron(III)Chloride
Covalent Ex: PBr5 Phosphorus(VI)Bromide

Question 7

Roman numerals 1-7

Answer 7

I, II, III, IV, V, VI, VII

Question 8

Ions at room temperature are…

Answer 8

Solid

Question 9

Chemical formula

Answer 9

Symbols tht represent # of atoms in a compound (H2O)

Question 10

Traditional system

Answer 10

Represents value of oxidation # for cations with MULTIPLE oxidations (old version of Stock, don’t need to k how to write only read)
Ionic Ex: plumbic cyanide Pb(CN)4
Covalent Ex: dinitrogen trioxide (N2O3)

Question 11

Exceptions

Answer 11

(First 3 polyatomics)
Mercurous= Hg2 +2
Ammonium=NH4 +
Hydronium=H3O +

Question 12

Binary Covalents

Answer 12

NONMETAL+NONMETAL

Ex: CO carbon(II)oxide

Question 13

Traditional system IONIC COMPOUNDS

Answer 13

Smallest oxidation -ous
2nd oxidation -ic + the “ide” OR polyatomic name
Ex: PbCl4 lead(IV)chloride

Question 14

Traditional system COVALENT

Answer 14

USE PREFIXES (mono, di, tri, tetra, penta) for quantity of atoms (1st one doesn't need mono) + ide
Ex: CI4 Carbon Tetraiodide

Question 15

Binary acids

Answer 15

HYDROGEN+NONMETAL
Hydro(nonmetal)ic acid
Ex: H2S Hydrosulfuric acid

Question 16

Ternary acids

Answer 16

HYDROGEN+POLYATOMIC ION
-ite become -ous acid (smaller)
-ate becomes -ic acid (larger)
Ex: HNO2 nitrous acid
HNO3 nitric acid
