Question

fission/fusion activity
using the periodic table of elements, predict the results of the nuclear reactions.
determine if the reaction is fission or fusion.
check the correct reaction

1. (_{92}^{235}u+_{0}^{1}n

ightarrow_{57}^{145}la + _{35}^{88}br+3_{0}^{1}n)

1. (_{1}^{2}h+_{1}^{3}h

ightarrow_{2}^{4}he + _{0}^{1}n)

1. (_{92}^{235}u+_{0}^{1}n

ightarrow_{52}^{137}te+_{}^{97}zr + 2_{0}^{1}n)

1. (_{6}^{13}c+_{2}^{4}he

ightarrow_{}^{16}o+_{0}^{1}n)

Explanation:

Step1: Recall fission and fusion definitions

Fission is a heavy - nucleus splitting into smaller nuclei, while fusion is light - nuclei combining into a heavier nucleus.

Step2: Analyze reaction 1

$^{235}_{92}U+^{1}_{0}n
ightarrow^{145}_{57}La + ^{88}_{35}Br+3^{1}_{0}n$. A heavy uranium nucleus splits, so it's fission.

Step3: Analyze reaction 2

$^{2}_{1}H+^{3}_{1}H
ightarrow^{4}_{2}He + ^{1}_{0}n$. Light hydrogen nuclei combine, so it's fusion.

Step4: Analyze reaction 3

$^{235}_{92}U+^{1}_{0}n
ightarrow^{137}_{52}Te+^{97}_{40}Zr + 2^{1}_{0}n$. A heavy uranium nucleus splits, so it's fission.

Step5: Analyze reaction 4

$^{13}_{6}C+^{4}_{2}He
ightarrow^{16}_{8}O+^{1}_{0}n$. Light - nuclei (carbon and helium) combine, so it's fusion.

Answer:

1. FISSION
2. FUSION
3. FISSION
4. FUSION
