Q

Nucleus radiation

A

Particle or electromagnetic radiation emitted from the nucleus during radioactive

20
Q

All man made isotopes are

A

Radioactive

21
Q

Why nucleus reaction are much more energetic than ordinary chemical reaction

A

Cause in nucleus reaction small amounts of mass are converted to large amounts of energy

22
Q

Why there is electron capture

A

An inner electron is pulled into the nucleus of an atom

23
Q

How is electron capture charge the nucleus?

A

Occurs rarely when there are too many protons than the number of neutrons
