Basic Bonding
Bonding that takes place between a metal and a nonmetal. (Taking/Giving one away)
What is ionic bonding?
One large unstable atom breaks into two or more.
What is fission?
The three types of radiation.
What are alpha, beta, and gamma?
What is nuclear chemistry?
Less stable isotopes.
What are radioactive isotopes?
Bonding that takes place between two non-metals. (Sharing an electron)
What is covalent bonding?
Two smaller atoms combine into one larger atom.
What is fusion?
Radiation that can be stopped by paper or plastic.
What is alpha?
Radiocarbon dating can be used to date artifacts that are how old?
50,000 years
Predicted that a small amount of matter could release a huge amount of energy in a nuclear reaction.
Who is Albert Einstein?
A chemical principle stating that atoms tend to gain, lose, or share valence electrons to achieve a stable configuration of eight electrons in their outermost shell.
What is the octet rule?
The nuclear reaction that produces radioactive waste.
What is fission?
Radiation that can be stopped by aluminium.
What is beta?
The only nuclear accident to happen in the US.
What is Three Mile Island?
The half-life of iron-59 is 44 days. If a sample originally contained 100 g of iron-59. How much would remain after 44 days, and how much would be remaining after 88 days?
50g and the 25g

Scandium is a metal that only loses electrons. It is located in the 4th row, 3rd column. How many electrons will it lose if it bonds?
Three (3)
Why we can't use nuclear fusion to generate electricity/energy in our country.
Radiation that releases an electron from the nucleus.
What is beta?
The scientist who was the first to "accidentally" discover radioactivity.
Who was Henri Becquerel?
During _______________________, atoms of one element can change into atoms of a different element.
What is nuclear decay?
