Multiple Choice

True or False: Covalent bonds occur when atoms share electrons.

• True

• False

Multiple Choice

An atom of arsenic has 5 valence electrons. What will it tend to do so it can be stable?

• Lose or give 5 electrons away

• Gain or share 5 electrons

• Lose or give 3 electrons

• Gain or share 3 electrons

Multiple Choice

What charge does an electron have?

• positive

• negative

• no charge

Ionic bonds form when an atom gains or loses valence electrons.

If it gains an electron, then the atom will become negatively charged.

If it loses and electron, then it will become positively charged.

​

​Ionic Bonds

​Examples:

-sodium & oxygen

-Magnesium & chlorine

​

Ionic bonds form between opposite sides of the table.

Hotspot

Which element is MOST LIKELY to form an ionic bond with IODINE?

We use a superscript to show the charge of an ion.
For example:
if fluorine gained one electron
F^-
if Lithium lost 2 electrons
Li²⁺

​

​If lose e = positive
If gain e = negative

​When an atom gains or loses electrons, it becomes an ion or an atom with a positive or negative charge

​FYI
Metal atoms tend to give away electrons
& nonmetal atoms receive atoms!

Another name for an ionic compound is SALT.


There are hundreds of different types of salt.

​Any compound that consists of atoms joined by an ionic bond is a salt!

They tend to have the following properties:

- brittle
- high melting point
- crystal structure
