Ionic Bonding

100

Ionic Bonding is...

Ionic bonding is the complete transfer of valence electrons between atoms.

200

How does Ionic Bonding differ from Covalent Bonding?

In Ionic bonding, atoms transfer electrons to each other. While atoms in covalent bonds share electrons between each molecule.

1. Magnesium Nitrate

2. Calcium Fluoride

Magnesium Nitride: Mg⁺² + N^-3 ---> Mg₃N₂

Calcium Fluoride: Ca⁺² + F^-1 ---> CaF₂

Covalent Bonding

100

What is Covalent Bonding?

Covalent Bonding is a type of chemical bonding that involves the sharing of electrons between atoms.

200

What two things generally form a covalent bond?

Two nonmetals

300

What are the two basic types of Covalent Bonds?

Polar and Non-polar

400

What is the type of covalent bond formed when electrons are shared unequally?

Polar Covalent

500

What is the chemical formula for the following covalent bond:

 1. Ammonia  

N^-3 + H⁺¹ ---> NH₃

Types of Chemical Reactions

100

What are the five types of chemical reactions?

Synthesis, Single replacement, Double replacement, Decompostion, and Combustion.

200

Is the following equation a decomposition, synthesis, single replacement, double replacement, or combustion reaction?

2NO₂--> 2O₂ + N₂

Decomposition

300

When metals are replaced is it a single replacement or double replacement?

Double Replacement

400

What is the difference between synthesis and combustion reaction?

Synthesis is when 2 or more reactants come together to make one product while combustion involves heat being applied to a formula.

500

How does a combustion reaction differ from the other types of chemical reactions?

Combustion reactions always involve O₂ and when the other reactants react with O₂ it makes oxide variations of the combined reactions.
