Match the particle to its' description

Question

column A

4 2 He

0 -1 e

y

is the same as a helium atom

is an electron

is pure energy

column B

gamma particle

beta particle

alpha particle

Answer 1

Here is the correct matching of the particles to their descriptions:

• 4 2 He → is the same as a helium atom (alpha particle)
• 0 -1 e → is an electron (beta particle)
• y → is pure energy (gamma particle)

So the final matches are:

• 4 2 He → alpha particle
• 0 -1 e → beta particle
• y → gamma particle

Answer 2

14
C
6

In the element above the mass number is and the atomic number is .

Blank 1:
Blank 2:

Answer 3

In the element notation \( \frac{14}{6}C \):

• The mass number (the number at the top) is 14.
• The atomic number (the number at the bottom) is 6.

So your answers would be:

Blank 1: 14
Blank 2: 6

Answer 4

Question 3

Which process occurs when two nuclei come together to form one bigger nucleus?

a
fission
b
fusion
c
radioactive decay

Question 4

Which process occurs when one nucleus splits to form two smaller nuclei?

a
fission
b
fusion
c
radioactive decay

Question 5

Scientists have been able to develop a nuclear fusion plant to generate energy.

True
False

Answer 5

Here are the answers to your questions:

Question 3: Which process occurs when two nuclei come together to form one bigger nucleus?
Answer: b fusion

---

Question 4: Which process occurs when one nucleus splits to form two smaller nuclei?
Answer: a fission

---

Question 5: Scientists have been able to develop a nuclear fusion plant to generate energy.
Answer: False

While research is ongoing, as of now, there is no fully operational nuclear fusion plant that generates energy for widespread use.

Answer 6

Match the nuclear reaction to its description.


Forms two lighter nucleus

Forms one heavier nucleus

Answer 7

Here are the matches for the nuclear reactions to their descriptions:

• Forms two lighter nuclei → Fission
• Forms one heavier nucleus → Fusion

So your matches would be:

• Fission → Forms two lighter nuclei
• Fusion → Forms one heavier nucleus
