How is the atomic mass changed?
When the number of neutrons changes, the atomic mass will change.
What element continue to decay until they finally become stable?
All elements above the atomic number of 83 are radioactive, but two elements that are under it are also radioactive. They are technetium (atomic number 43) and promethium (atomic number 61). Radioactive elements are elements that decay until stable. =)
If an element is radioactive is it's nucleus unstable?
Yes,The element is radioactive due to the instability of its nucleus.See the related question below for more information.
The half-life of a radioactive element is?
The time it takes for half of the atoms to decay, and become some other type of atom.
Are all elements periodically change to become new element s?
No. Only radioactive elements, which undergo radioactive decay can change to different elements.
How is the atomic mass changed?
When the number of neutrons changes, the atomic mass will change.
Does a radioactive element become stable after its mass number become less than 82?
Not always -- Hydrogen-3 is radioactive, for example.
How can element 92 become element 83?
Through radioactive decay, because Uranium (element 92) is unstable.
What element continue to decay until they finally become stable?

How uranium nucleus become stable?
Being radioactive, uranium is not a stable element.
If an element is radioactive is it's nucleus unstable?
Yes,The element is radioactive due to the instability of its nucleus.See the related question below for more information.
Why does radioactive decay happen?
Radioactive decay happens because unstable atomic nuclei release energy in the form of radiation to become more stable.
Changing the number of protons in an atom would change what?
If an atom were to change the number of protons it had than it would change the atomic number and therefore become a different element. Radioactive decay is one example of this, for example, alpha decay is when a radioactive nucleus emits an alpha particle (2 protons + 2 neutrons) and in doing so, becomes a nucleus of a different element. Polonium-212 decays to Lead-208 in this way.
The half-life of a radioactive element is?
The time it takes for half of the atoms to decay, and become some other type of atom.
Do Elements become radioactive when the strong nuclear force overcomes the repulsive electrostatic force?
No. Radioactive elements are normally a result of the atom actually being an isotope of that element. An isotope is an atom of an element that has a different amount of neutrons than the norm. For example, the normal amount of neutrons in a Carbon atom is six, but Carbon-14 has eight, and Carbon-16 has ten. These isotopes are normally radioactive.
What would happen to an atom if the number of protons in the nucleus changed?
It would become a different element. It could become radioactive.
What elements that emit atomic particles are called?
Elements that emit atomic particles are typically referred to as radioactive elements. These elements undergo radioactive decay and emit particles such as alpha particles, beta particles, or gamma rays as they try to become more stable.
