nuclear equations.

Question 1

alpha: He⁴₂
what does the ₂ symbolise and what is it equal to?

Answer 1

number of protons and is equal to the relative charge.

Question 2

alpha: He⁴₂
what does the ⁴ symbolise for?

Answer 2

mass number.

Question 3

beta: e⁰₋₁
what does the ⁰ symbolise?

Answer 3

mass number.

Question 4

beta: e⁰₋₁
what does the ₋₁ symbolise?

Answer 4

relative charge.

Question 5

gamma: ⅋⁰₀
what does the ₀ symbolise?

Answer 5

relative charge.

Question 6

neutron: n₀¹
what does the ¹ symbolise?

Answer 6

mass number.

Question 7

neutron: n₀¹
what does the ₀ symbolise/ equal to?

Answer 7

relative charge.

Question 8

changes in nucleus after alpha radiation: change in mass number?

Answer 8

-4 : loss of 2 neutrons and 2 protons.

Question 9

changes in nucleus after alpha radiation:
change in relative charge?

Answer 9

-2 🠒 loss of 2 protons.

Question 10

changes in nucleus after beta radiation: change in mass number?

Answer 10

0.
electron has almost no mass.

Question 11

changes in nucleus after beta radiation: change in relative mass?

Answer 11

+1: neutron has changed into a proton so there is 1 more proton.

Question 12

representing alpha radiation using a symbol equation: (ᶻrepresenting subscript.)
(ᶻ to be under the ᵃ ⁻⁴.)
ᴬᶻ X 🠒 ⁴₂ He + ᵃ ⁻⁴ᶻ₋₂
what does the ᵃ ⁻⁴ represent and what does the ᶻ₋₂ represent?

Answer 12

mass is concerved.
charge is conserved.

Question 13

representing beta radiation using a symbol equation:
(ᶻ₊₁ should be together beneath ᵃ and subscript.)
ᴬᶻ X 🠒 ⁰₋₁ e +ᵃ ᶻ₊₁ Y.
what does the ᵃ represent and what does the ᶻ₊₁ represent?

Answer 13

mass is concerved.
charge is conserved.
