Types of Radioactive Decay

Question 1

Identify whether each reaction represents a chemical reaction or a nuclear reaction by filling in the blank with the word ‘chemical’ or ‘nuclear’.Cl + H 2HClThis represents a reaction.

Revolt · Accepted Answer

"chemical"; "nuclear"

Question 2

H + H He + nThis represents a reaction

Revolt · Accepted Answer

nuclear

Question 3

C

Revolt · Accepted Answer

intermediate

Question 4

D

Revolt · Accepted Answer

highest

Question 5

E

Revolt · Accepted Answer

thin cardboard

Question 6

Explain why isotopes of the same element behave differently in nuclear reactions but not in chemical reactions.

Revolt · Accepted Answer

Isotopes of the same element differ only in neutron numbers. Nuclear reactions involve changes to the protons or neutrons in an atom’s nucleus, but not changes to its electrons. Chemical reactions involve changes to the electrons in atoms, but not changes to its protons or neutrons. Isotope behavior only differs when a reaction involves neutrons.
