What is an alpha particle?

Back

An alpha particle is a type of nuclear radiation consisting of 2 protons and 2 neutrons, equivalent to a helium-4 nucleus.

What happens to an element when it emits an alpha particle?

Back

The element loses 2 protons and 2 neutrons, resulting in a new element with a lower atomic number.

Front

What is half-life?

Back

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

Front

How do you calculate the remaining amount of a radioactive substance after a certain time?

Back

Use the formula: Remaining amount = Initial amount * (1/2)^(time elapsed / half-life).

What is a beta particle?

Back

A beta particle is a high-energy, high-speed electron or positron emitted during radioactive decay.

Front

What charge does a beta particle have?

Back

A beta particle has a charge of -1.

Front

What is the significance of the number of protons in an atom?

Back

The number of protons determines the element's identity and its position on the periodic table.

Front

What is technetium-99 used for?

Back

Technetium-99 is commonly used in medical imaging and diagnostic procedures.

Front

What is the difference between isotopes?

Back

Isotopes are variants of the same element that have the same number of protons but different numbers of neutrons.
