alpha particle, He nucleus
Of course. Chemistry still applies, and that is based on the electron configuration, not the nucleus, per se.
Yes,The element is radioactive due to the instability of its nucleus.See the related question below for more information.

Nobelium is a radioactive, artificial chemical element.
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.
Of course. Chemistry still applies, and that is based on the electron configuration, not the nucleus, per se.
If an element is radioactive, it refers to the stability of their atomic nucleus. If that atomic nucleus is not stable, it is considered radioactive.
A radioactive element is an element that has an unstable nucleus, leading to the emission of radiation in the form of alpha, beta, or gamma particles. This emission is a result of the element's attempt to achieve a more stable configuration. Common examples of radioactive elements include uranium, thorium, and radium.
its nucleus is unstable
A chemical element with a mass number of 3 is tritium, which is a radioactive isotope of hydrogen. Tritium has two neutrons in its nucleus in addition to its lone proton.
