Can you help me explain how the mass and the atomic numbers of an alpha particle can be used to determine the number of neutrons in the particle by using this table?

Answer 1

The atomic mass is 4. The atomic number (number of protons) is 2. So there must be two neutrons in an alpha particle. 2+2=4.

Answer 2

Since an alpha particle is a helium nucleus, it has two neutrons as well as two protons. The atomic number gives the number of protons, and you subtract that from the mass to get the number of neutrons. The symbol given in that table for a beta particle is wrong.

Answer 3

They relate to physics and chemistry Neutrons and Protons are interior the nucleus of an element and the Electrons bypass around them. interior the Periodic table the Atomic extensive type is the style of Protons and neutrons is what's left once you minus it from that. Electrons are no longer counted as a extensive determination on the periodic tablr using fact they're so mild they do no longer likely impression the burden of it. would desire to appreciate something approximately them in basic terms ask.
