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

There are 2 magnesium ions to every bromide ion

The following properties are all characteristics of ionic compounds EXCEPT

high melting and boiling points

conduct electricity when dissolved in water

Ionic bonds could be best described as:

An electrostatic attraction between oppositely charged ions

A bond formed when 2 atoms share electrons

An electrostatic attraction between anions

In a lattice structure oppositely charged ions :

have a strong electrostatic attraction

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

Ionic compounds are typically hard but brittle because...

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

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

Why are some ionic compounds so colorful?

they contain a transition metal

they glow when electricity is passed through them

they absorb a lot of ultraviolet rays of light

they are found naturally on Earth
