What is half-life?

Back

Half-life is the time required for half of the radioactive atoms in a sample to decay into a more stable form.

What happens to the atomic number during alpha decay?

Back

During alpha decay, the atomic number decreases by 2.

5.

FLASHCARD QUESTION

Front

What happens to the mass number during beta decay?

Back

During beta decay, the mass number remains the same, but the atomic number increases by 1.

6.

FLASHCARD QUESTION

Front

What type of radiation has no mass?

Back

Gamma radiation has no mass.

7.

FLASHCARD QUESTION

Front

How do isotopes of the same element differ?

Back
