For example, this can occur when the shape of the nucleus undergoes a change.

Neither the mass number nor the atomic number is changed when a nucleus emits a The time required for half of the atoms in any given quantity of a radioactive isotope to decay is the half-life of that isotope. For example, the half-life of C is 5730 years, thus it is useful for dating archaeological material.

decay will have a mass and charge different from those of the original nucleus.

A change in nuclear charge means that the element has been changed into a different element.

Several materials other than uranium were also found to emit these penetrating rays.

Only through such radioactive decays or nuclear reactions can transmutation, the age-old dream of the alchemists, actually occur.

The mass number, He is two, and therefore the atomic number of the nucleus, the number of protons, is reduced by two.

Since the electric charges of the proton and the electron are 1 and -1 respectively (in units of the proton charge), the net charge of the atom is zero.

At present, there are 112 known elements which range from the lightest, hydrogen, to the recently discovered and yet to-be-named element 112.
