Chapter 2: Atoms, Ions, and Molecules

Question 1

What is the type 1 binary ionic?

Answer 1

The metal cation has a fixed charged. This means that there is 1 specific ion chrage that the metal can have

Question 2

How do you name a simple compund that is a binary type 1?

Answer 2

First you write the name of the metal cation

Then anion name= (stem name) + “ide”

Question 3

Name the elements that only have 1 possible cation charge

Answer 3

All group 1A metals (M^1+)
All group 2A metals (M^2+)
Al   (Al^3+)
Ga  (Ga^3+)
Ag  (Ag^+)
Zn  (Zn^2+)

Question 4

In a binary ionic ccompound what groups are associated?

Answer 4

Metal and Non-metal

Question 5

What would happen if you had a metal cation with variable charge?

Answer 5

We will be dealing with a type 2 binary ionic compound

Question 6

What groups of metal have varable charge?

Answer 6

Transition metals

Question 7

How do you specify a cation if it has variable chrage?

Answer 7

You would need to use Roman numeral for the charge

Question 8

How do you name a simple compound that is a binary type 2?

Answer 8

It’s the same as naming a simple compound for binary type 1

Question 9

How do you know when to use binary covalent?

Answer 9

To know that it is a covalent the elements are on the right side of the periodic table
They would be both non-metals

Question 10

In a binary covalent, what is a rule that you must follow?

Answer 10

You can not use “mono” for the first element

Question 11

What are polyatomic ions?

Answer 11

Compounds with 3 or more atoms

Question 12

What do we do if we have a situation where our compound contains a polyatomic ion, but it’s not the anion?

Answer 12

We would name this by writing the name of the cation first

For the anion, we would take the element stem and attach “ide” suffix at the end

Question 13

When naming an acid how do you define it?

Answer 13

Define an acid as being any compound which as H+as the cation

Question 14

What is the general naming formula with acids that don’t contain oxygen?

Answer 14

Hydro–(anion stem)– ic acid

Question 15

If the anion ends with –ate what is the general naming formula?

Answer 15

(polyatomic stem–) –ic acid

Question 16

If the anion ends with –ite what is the general naming formula?

Answer 16

(polyatomic stem–) –ous acid

Question 17

What is a great way to remember the naming formula when an acid contains oxygen?

Answer 17

I ATE it and got sICk

I took a bITE and got nauseOUS

Question 18

Name the compound:

NH4Cl

Answer 18

Ammonium chloride

Question 19

Name the compound:

Mg3(PO4)2

Answer 19

Magnesium phosphate

Question 20

Name the compound:

MgCl2

Answer 20

Magnesium chloride

Question 21

Name the compound:

HClO

Answer 21

Hypochlorous acid

Question 22

What does the number of protons determine?

Answer 22

Determines what element you have

Question 23

What does the symbol notation “Z” stands for?

Answer 23

Atomic number/nuumber of protons

Question 24

What does the symbol notation “A” stand for?

Answer 24

Mass number/#protons + #neutrons

Question 25

What are isotopes?

Answer 25

The same number of protons, but the different mass number

Question 26

What does the symbol notation "X" stand for?

Answer 26

Element symbol

Question 27

What are anions?

Answer 27

They carry negative charge

Question 28

How is an anion formed?

Answer 28

An atom gains an electron

Question 29

What are cations?

Answer 29

They carry positive charge

Question 30

How is an cation formed?

Answer 30

An atom loses an electron

Question 31

What do alkali metals have in common?

Answer 31

They don't have stable number of electrons

Question 32

When forming a compound does Group 1A lose or gain electrons?

Answer 32

Lose 1 electron

Question 33

What groups are in Group 2A?

Answer 33

Alkali earth metals

Question 34

What group are alkali earth metals founds in?

Answer 34

Group 2A

Question 35

Do alkali earth metals lose or gain electrons?

Answer 35

They lose 2 electrons

Question 36

What group are in Group 7A?

Answer 36

Halogens

Question 37

What group are halogens found in?

Answer 37

Group 7A

Question 38

Do halogens gain or lose electrons?

Answer 38

They gain 1 electron

Question 39

What are the two different types of bonds?

Answer 39

Covalent and ionic bonds

Question 40

What are coalent bonds?

Answer 40

They have equal sharing of electrons between 2 atoms | Are typically seen with non-metals and non-metal bonds

Question 41

What are ionic bonds?

Answer 41

Electrons transferred between 2 atoms | Are typically seen with metal-non metal bonds
