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.

mechanics (greek   is that area of science concerned with the behaviour of physical bodies when subjected to forces or displacements, and the subsequent effects of the bodies on their environment. the scientific discipline has its origins in ancient greece with the writings of aristotle and archimedes[1][2][3] (see history of classical mechanics and timeline of classical mechanics). during the early modern period, scientists such as galileo, kepler, and newton laid the foundation for what is now known as classical mechanics. it is a branch of classical physics that deals with particles that are either at rest or are moving with velocities significantly less than the speed of light. it can also be defined as a branch of science which deals with the motion of and forces on objects. the field is yet less widely understood in terms of quantum theory.
