It isn't really an ELEMENT that is unstable, but an ISOTOPE. That means that in general, for the same element, some atoms will decay, and some will not - the difference being the number of neutrons in the nucleus.
Increasing the ratio neutrons/protons in the nucleus the atom become unstable.
An alpha particle is a helium nucleus, which consists of 2 protons and 2 neutrons. When an unstable nucleus emits an alpha particle, it loses 2 protons, which means its atomic number will be reduced by 2.
The two aspects that cause the nucleus of any element atom to be unstable are:not have the specific neutron/proton ratio to be a stable nucleus, and orhaving number of protons that exceeds the stability limit (exceeding 83).Referring to question below for more information.
Yes,The element is radioactive due to the instability of its nucleus.See the related question below for more information.

The strong nuclear force doesn't balance the electrostatic force.
A stable nucleus is one which will not decay, whereas an unstable nucleus will decay at some point, which cannot be predicted as decay is a random process, by alpha or beta decay.
Radioactive elements have unstable nucleii. When an unstable nucleus decays it emits energy in the form of electromagnetic waves and heavy particles and in the process forms new nucleii.
