Alpha,Beta,Gamma Radiation

Question 1

What is alpha?

Answer 1

a nucleus containing 2 protons and 2 neutrons, Identical to a helium nucleus

Question 2

What is Beta?

Answer 2

high energy, high energy electron or position emitted in the radioactive decay or an atomic nucleus like potassium 40

Question 3

What is Gamma?

Answer 3

high frequency waves like x-rays

Question 4

What is Alpha Decay?

Answer 4

when a an alpha particle is emitted from a nucleus, it loses 2 protons and neutrons. Atomic mass decreases by 4, Atomic number by 2.

Question 5

Beta(-) decay occurs when?

Answer 5

occurs when radioisotopes have too many neutrons

Question 6

Beta (-) decay l, what happens?

Answer 6

a neurton changes into a proton plus an electron. The proton stays in the neutron, electron leaves the atom with high energy. Atomic number +1, Atomic mass remains

Question 7

Beta (+), when does it occur?

Answer 7

occurs when radioisotopes have too many protons

Question 8

Beta (+) decay?

Answer 8

a proton covered into a neutron and a positive beta particle (B+).A positron, has the mass of an electron but a positive charge.

Question 9

Gamma decay?

Answer 9

Gamma doesn’t alter the number of protons or neutrons.It has the effect of moving the nucleus from a higher to a lower energy state (unstable to stable)
