Atomic and Nuclear Phenomenon Flashcards
1
Q
Energy of a photon of light equation
A
E= hf
2
Q
Plancks Constant
A
6.6 x 10^-34
3
Q
Maximum Kinetic Energy of an ejected electron Equation
A
K = hf - W
4
Q
Mass Defect
A
the difference between the sum of the masses of nucleons in the nucleus and the mass of the nucleus, results from the conversion of matter to energy (binding energy)
5
Q
Binding Energy Equation
A
E = mc^2
6
Q
Alpha Decay
A
Loss of 4 on atomic number and loss of 2 on charge (essentailly a helium atom)
7
Q
-Beta Decay
A
No change in atomic number but a gain of 1 on charge
8
Q
+Beta Decay
A
No change in atomic number but a loss of 1 on charge
9
Q
Gamma Decay
A
lower the energy of the parent nucleus and emits a gamma ray
10
Q
Electron Capture
A
no change in atomic number, but a loss in charge by 1
reverse of -Beta Decay essentially
