• Proton

• Electron

• Beta

• Neutron

The charge of any nucleus is

Isotopes of an element have different numbers of

Answer explanation

Isotopes of an element differ in the number of neutrons they contain. This variation in neutrons leads to different atomic masses, while the number of protons remains constant, defining the element itself.

How many neutrons does plutonium have?

What can be emitted from an unstable nucleus? Select all that are correct

• Alpha

• Beta

• Gamma

• Neutrons

A beta particle is a fast moving

• proton

• neutron

• electron

• alpha

If Lawrencium decayed by giving out an alpha particle, what would be the atomic number of the daughter nucleus formed?

If Einsteinium underwent beta decay, what would be the atomic number of the resulting daughter nucleus?

If Beryllium underwent neutron emission, what would be the mass number of the resulting daughter nucleus?

An atom which loses an electron becomes charged and is now known as an
