11-1: Types of Nuclear Decay Reaction

Question 1

Elements above what atomic number do not fall in the belt of stability?

Answer 1

83

Question 2

Elements found above/below the belt of stability need to (?/?) their (?/?) ratio?

Answer 2

lower/raise
neutron/proton

Question 3

Gamma Ray Emission

Answer 3

High energy radiation emitted that does not change the proton or neutron numbers

Question 4

Alpha (a) Decay

Answer 4

Loss of an alpha particle, or a helium nucleus (2 protons + 2 neutrons)

Question 5

Beta Decay

Answer 5

Nucleus ejects a beta particle and a neutrino (neutron becomes a proton)

Question 6

Positron Emission

Answer 6

Also called B+ Decay
Nucleus ejects a positron and a neutrino (proton becomes a neutron)

Question 7

What is alpha decay prevented by?

Answer 7

Paper, clothing

Question 8

What is B- decay prevented by?

Answer 8

Aluminum sheet

Question 9

What is B+ decay prevented by?

Answer 9

Aluminum sheet

Question 10

What is gamma emission prevented by?

Answer 10

Lead sheet

Question 11

What are the charges for the different types of decay?

Answer 11

Alpha = 2+
Beta- = 1-
Beta+ = 1+
Gamma = 0

Question 12

What are the masses for the different types of decay?

Answer 12

Alpha = 4
Everything else = 0

Question 13

Which types of decay cause transmutations?

Answer 13

Everything except gamma emission

Question 14

Which types of decay are natural/artificial?

Answer 14

Everything is natural

Question 15

Which types of decay are spontaneous?

Answer 15

Everything
