nuclear equations.

Question 1

what are nuclear equations?

Answer 1

represent the reactants and products in radioactive decay, nuclear fission, or nuclear fusion.

Question 2

what is an alpha particle is represented by?

Answer 2

₂⁴He.

Question 3

what is a beta particle represented by?

Answer 3

⁰₋₁e.

Question 4

what happens when an alpha particle is emitted and why?

Answer 4

mass number of the element is reduced by 4.
atomic number is number reduced by 2.
2 protons and 2 neutrons are emitted from the nucleus.

Question 5

what is an example of : what happens when an alpha particle is emitted.?

Answer 5

²¹⁹₈₆Radon → ²¹⁵₈₄Polonium + ⁴₂He

Question 6

what happens with beta decay and why?

Answer 6

mass number does not change.
atomic number is increased by 1.
neutron turns into a proton and an electron and the electron is emitted.

Question 7

what is an example of: what happens when an beta particle undergoes decay.?

Answer 7

¹⁴₆Carbon → ¹⁴₇Nitrogen + ⁰₋₁e

Question 8

what does the emission of a gamma ray cause?

Answer 8

doesn’t cause a change in mass or the charge of the nucleus.
