The symbol for a radioactive nuclide is mc028-1.jpg. which statement is correct? the atomic number of the radioactive nuclide is 210. the mass number of the radioactive nuclide is 294. the number of neutrons present in the nucleus of each atom is 126. the number of protons present in the nucleus of each atom is 210.

Assuming the image as per the attachment, then the radionuclide is then,

The element is Polonium - 210 which is an isotope of Polonium and has an atomic weight of 210

And the as given the atomic number of Polonium is 84,

Which indicates that it has 84 protons present in its nucleus and 84 electrons orbiting around its nucleus.

To calculate the number of neutrons we can simply subtract atomic weight by atomic number and get the neutrons present in its nucleus.

∴ it will be 210 – 84 = 126 neutrons

This will make the Po unstable and it will be emitting very weak gamma rays.

answer: a chemical reaction

explanation:

im not wrong

because natural gas is colorless, odorless, and tasteless, distributors add mercaptan (a chemical that smells like sulfur) to give natural gas a distinct unpleasant odor (it smells like rotten eggs). they locate the types of rock that are likely to contain natural gas deposits.
