What is the attraction that holds oppositely charged ions together in a bond?
Metallic bond
Covalent bond
Electrostatic Attraction
electromagnetic force
What does the law of conservation of mass state?
Matter can be destroyed when there is a chemical reaction
Matter can be created during a chemical reaction
Substances (matter) cannot be destroyed or created

Why do atoms want to bond together?
Atoms form bonds in order to become stable and obtain a full outer shell
Atoms do not want to bond together
Atoms want to form in order to create an explosion and create a new substance
Atoms form bonds in order to become unstable with a full outer shell
Which atom does not usually form bonds and why
Carbon because it is a nonmetal and nonmetals don't like to form bonds
Sodium because it is an alkali metal. This element does not want to take in any electrons
Neon because it is a stable noble gas. This element does not want to take in any electrons
Iron because it is a transition metal. This element wants to take in as many electrons as possible.

How are ionic bonds formed?
They are formed by sharing a proton
They are formed when when one atoms takes a proton from another

What is the octet rule?
The valence shell of an atom is full when the last energy level is bonded with another element
The valence shell of an atom is considered stable when there are 10 electrons on the outer shell
There must be at least 2 protons on the outer shell
The valence shell of an atom is considered to be full if the outer most energy level contains 8 electrons
