300
What are the masses of the three subatomic particles?
Proton = 1 amu Neutron = 1 amu Electron = <<<<1 amu - mass is negligible
300
What is the difference between fission and fusion?
Fission - Nuclear decay Fusion - elements fusing together; occurs at high temperatures (on the sun)
300

A triple bond
400
Contrast the size, electronegativity, reactivity, and ionization energy of carbon and oxygen.
O has higher reactivity, electronegativity, and ionization energy. C is larger.
400
Where are the three subatomic particles located within an atom?
Protons and neutrons are in the nucleus and electrons orbit the nucleus.
400
Why do certain elements undergo nuclear decay?
They are unstable and too large
