Metals tend to

gain electrons

lose electrons

If my charge becomes 2+ what does that say about me?

I am stealing 2 electrons

I am losing 2 electrons

I am in period 2

I have an atomic # of 2

If I gain electrons I become

Positive because I've added to my atom

negative because I've added electrons

same because i'm balanced

equal because now I have electrons

Cation

10.

When a metal loses electrons, it becomes this type of ion.

anion

cation

11.

When an ionic compound is formed, its charge is

negative

neutral (no charge)

positive

12.

The first step in naming an ionic compound is always...

Naming the anion

Changing the ending to -ide

Naming the cation

Writing the cation charge

13.

What is the charge on a Hydrogen ion?

14.

What is the charge on an Aluminium ion?

15.

What is the charge on a chloride ion?

-1

16.

What is the charge of Neon?

-1

17.

Magnesium bromide is an ionic compound with the chemical formula MgBr₂. What does the "2" tell you?

There are 2 bromide ions for every magnesium ion

Bromide has a 2- charge

Bromide has a 2+ charge

There are 2 magnesium ions to every bromide ion

18.

In what form can an ionic compound conduct electricity?

when dissolved in water

as a solid

as a crystal

when warmed slightly

19.

Which of the following is a property of an ionic compound?

high melting point

soft

malleable

liquid at room temperature

20.

Ionic compounds can conduct electricity as a solid

true

false

21.

The following properties are all characteristics of ionic compounds EXCEPT

high melting and boiling points

soft

crystal lattice structure

conduct electricity when dissolved in water

22.

What is the name of the three-dimensional pattern that forms when ions bond?

a crystal lattice

a chemical compound

an ionic bond

an ionic chalice

23.

Ionic bonds could be best described as:

A bond formed when 2 atoms share electrons

A firm handshake

An electrostatic attraction between oppositely charged ions

An electrostatic attraction between anions

24.

In a lattice structure oppositely charged ions :

Will repel

have a strong electrostatic attraction

25.

The diagram shows

the transfer of electrons from the metal to the non-metal

an ionic bond between oppositely charge ions

the number of electrons lossed or gained by each ion

All of the above

26.

Ionic compounds are typically hard but brittle because...

when you force like charges together they break the crystal lattice structure

they are made of glass

when you try to bend them they only form thin wire like shapes

they were made using very high amounts of heat and are fragile

27.

Why are some ionic compounds so colorful?

they glow when electricity is passed through them

they contain a transition metal

they absorb a lot of ultraviolet rays of light

they are found naturally on Earth
