a beta particle. the nucleus is made of protons (+) and neutrons. but neutrons can transform into an electron and a proton. when that happens in the nucleus, the proton stays in the nucleus while the electron shoots out at incredibly high speeds. that high speed electron is called a beta particle. the proton that stays is added to the other protons to increase the atomic number

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.


If an isotope undergoes beta emission?

If an isotope undergoes beta emission, a neutron in the nucleus is transformed into a proton, along with the emission of a beta particle (an electron) and an antineutrino. This process increases the atomic number of the nucleus by one but leaves the mass number unchanged.


What is the atomic number of tritium?

The atomic number of tritium is 1. It is a radioactive isotope of hydrogen with two neutrons and one proton in its nucleus.


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 happens when a radioactive isotope decays?

It emits an electron and an antineutrino and increases by one in atomic number while ending up with one fewer neutrons, or it emits a positron and a neutrino and decreases by one in atomic number while ending up with one more neutron. In both cases the total number of protons and neutrons remains unchanged, and the number of orbital electrons will eventually change to match the new atomic number.


What is the atomic number and mass number of radioactive nitrogen?

The atomic number of nitrogen is 7, and the most common isotope of nitrogen, nitrogen-14, has a mass number of 14.


What is an isotope that has the atomic number 190 and mass number 78?

There is no such isotope. The highest atomic number is 118. The question is erroneous. The isotope platinum-190 has the atomic number 78, the mass number 190 and the atomic mass 189,959 932(6).


What element has a mass of 190?

Iridium has an atomic mass of 192 (192.217)


What is the atomic number of Ar?

That depends on the isotope, as Argon has three different stable isotopes and many different radioactive isotopes.


How can you dertermine the number of neutrons in a isotope?

Subtract the atomic number of the isotope from its atomic mass number to obtain the number of neutrons in an isotope.


How does the atomic number relate to the number of protons in an atom?

Atomic Mass (of an isotope) - number of protons (of an isotope) = number of neutrons (of an isotope)


What is the atomic number for radio isotope?

There are radioactive isotopes of all elements, so it depends on what radioisotope you are talking about. For example, carbon has 6 protons, so its atomic number is 6 - whether it is the stable carbon-12, or the radioactive carbon-14.
