Types of Radiation
The 3 types of radioactive decay
Alpha, Beta, Gamma
23191Pa → ____ + 22789Ac
42He
(True or false) C-13 and C-14 are isotopes of one another.
The most damaging of radioactive decay
Alpha
The atomic number tells us
The number of protons
Gamma radiation is made up of
Just energy, no particles
20682Pb + ____ → 21084Po
42 He
(True or False) Gamma Decay can occur on its own
False
The radioactive decay with the most piercing power
Gamma
Atomic mass is calculated how?
(Normal not average)
Protons + Neutrons
Alpha decay is made up of.
2 protons and 2 neutrons
____ → 0-1 e + 21484 Po + 00 ɣ
21485 At
73Li
Alpha decay can be stopped by
Paper, skin, clothing
This is the number of capital letters in an element's symbol on the periodic table.
1
This decay has no mass and no charge
Gamma
Write a nuclear equation of 23391 Pa if it underwent alpha decay.
23391 Pa --> 42 He + 22989 Ac
(True or False) 6329 Cu and Cu-63 give the same information
True
Beta Decay can be stopped by
Thick plastic or thin sheet of aluminum
These are the two numbers of an element found on the periodic table.
Average Atomic Mass & Mass Number
Beta-Decay occurs when
A neutron turns into a proton and shoots out an electron
Write a nuclear equation of 19885 At if it underwent beta decay.
19885 At --> 0-1 e + 19886 Rn
This is the definition of nuclear decay.
the spontaneous emission of particles and/or energy from an atomic nucleus
Gamma radiation can be stopped by
Several inches of concrete and lead
Locations of protons, neutrons, and electrons in the atom
Protons and neutrons - nucleus
Electrons - Shells (or electron cloud)
