it decreases by half as it goes on.for example if the atomic mass number is 16 it decrease to 8 then to 4 then 2 and it goes on until it finishes

In a radioactive substance, the Atomic Mass number may change as a result of radioactive decay. During radioactive decay, radioactive atoms undergo nuclear reactions, which can lead to the emission of radioactive particles such as alpha or beta particles. These emitted particles can cause a change in the number of protons and neutrons in the nucleus, resulting in a different atomic mass number for the resulting atom or isotope.

Do radioactive elements differ in atomic number?
yes
What is the name of the element with the lowest atomic number?
Technetium - its atomic number is 43.
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. =)
The atomic number increases but the atomic mass stays the same?
The atomic number increases but the atomic mass stays the same after the emission of a beta particle by a radioactive atom.
What is uraniums atomic number?
Uranium is a radioactive element. It is in the f block. We use it for make energy.
What atomic number is 84?
Po is a radioactive element.It has the 84 atomic number.
What is a slogan for molybdenum?
radioactive, artificial, metal, atomic number 101
What is the atomic number and mass number of radioactive nitrogen?
sixteen
What is the atomic number of radioactive nitrogen?
Nitrogen is a non metal element. Atomic number of it is 7.
Do radioactive elements differ in atomic number?

Atomic number for uruanium?
This one is based one uranium. It is a radioactive one. Uraniums atomic number of that is 92.
A radioactive isotope has eight neutrons Write the atomic number and mass number of this radioactive nitrogen as a chemical symbol with a subscript and superscript?
The atomic number of nitrogen is 7. When it is a radioactive isotope you add the number of neutrons to the atomic number (equaling 15). You then write 15 over 7 next to a capital 'N' representing Nitrogen.
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. =)
How is it possible for an element to decay forward in the periodic table that is to decay to an element of higher atomic number?
When elements form other elements of a higher atomic number, the process by which that happens is called nuclear fusion, not radioactive decay, and it normally happens only inside stars.
Radioactive elements comprise a majority?
Yes. Stable elements are 83 elements. all elements above that of atomic number 83 (Bismuth) are radioactive. Radioactive isotopes are of the order of 1500 radioactive isotope.
Heaviest element that is highly radioactive?
The heaviest element that is highly radioactive is Ununoctium, which has an atomic number of 118.
