Chapter 2 Particles And Their Properties

Question 1

Proton P

Answer 1

Charge = +1

Antiparticle and symbol = antiparticle -P
Charge = -1

Rest energy MeV = 938 (x10-13 Joules)

Interaction + Strong, weak, electromagnetic

Question 2

Neutron n

Answer 2

charge = 0

Antiparticle and symbol = antineutron -n
charge = 0

rest energy MeV = 939

Interaction = Strong, weak

Question 3

electron e

Answer 3

Charge = -1

Antiparticle and symbol = Positron e+
Charge =+1

Rest energy = 0.511

Interaction = weak, electromagnetic

Question 4

Neutrino v

Answer 4

Charge = 0

Antineutrino and symbol = -v
Charge = 0

Rest energy = 0

Interaction = weak

Question 5

Muon μ−

Answer 5

Charge = -1

Antiparticle and symbol = antimuon μ+
Charge = +1

rest energy Mev = 106

Intercation = weak, electromagnetic

Question 6

pions

π+ π0 π−

Answer 6

Charge = +1,0,-1

Antiparticle and symbol = 
π+ = π− 
π− = π+
π0 = π0 
Charge = -1,0-,+1

Rest energy Mev = 140,135,140

Interaction = strong, electromagnetic

Question 7

kaons

K+, K0,K-

Answer 7

Charge = +1,0,-1

Charge = -1,0,+1

Rest energy MeV = 494,498,494

Interaction = strong, electromagnetic
