Ionic Bonds 

What proves these 2 elements can form an Ionic Bond?

             Learning Intention: 

What? We are learning  how to write the names and chemical formulas for ionic bonds. 

Why?  In order to  use the International Union of Pure and Applied Chemistry (IUPAC) nomenclature correctly. 

             Success Criteria

I can: 

- Identify the properties of ionic bonds.

-Develop formulas for ionic bonds

- Identify the IUPAC nomenclature for ionic bonds when given an ionic compound formula. 

00:15

How are Ions formed?

1. From neutral charges balancing out.
2. Only from losing electrons
3. Only from gaining electrons
4. Losing OR gaining electrons

00:24

What happens to electrons that are lost or gained in an atom?

1. They disappear
2. They are transferred to another atom
3. The y randomly appear in other atoms
4. Scientists do not know yet.

00:34

What is formed when Na loses 1 electron?

1. A new Atom
2. A Sodium Ion
3. Same Atom but new Atomic Number
4. Any type of Ion

00:42

When the electron from Na is transferred to Cl, what is formed?

1. A Cl Ion
2. A Na Cl Ion
3. Another atom
4. Another element

01:08

The bond between Na+ and Cl- creates

1. another element
2. Charged Atom
3. Ionic Compound
4. a new atomic number

01:23

What is the
resulting
Ionic Compound
for Mg and O?

1. Mg+O2+
2. Mg2-O2+
3. Mg2+O2-
4. Mg2-O+

02:36

What is an Ionic Bond?

1. Motion attraction between oppositely charged ions.
2. Electrostatic attraction between like charged ions.
3. Electrostatic attraction between neutrally charged atoms
4. Electrostatic attraction between oppositely charged ions.

02:42

When an Ionic Compound is formed, why MUST the charges be balanced?

1. so that the ionic compound has an overall neutral charge
2. so that the ionic compound has an overall positive charge
3. They do not need charges to balance.
4. so that the ionic compound has an overall negative charge
