A beta particle is the same as B. An electron. This is termed as such for a specific beta radioactive decay reaction.
Hello there!
The atomic number of an atom tells you an element's identity, and informs you of how many protons are present in the nucleus of the atom.
For example;
Potassium is an element with the symbol "K" on the periodic table that belongs in the Alkali Metal group, and has an atomic number of 19. This means that Potassium has 19 protons.
I hope this helps!
The number of protons can be calculated by subtracting 207 with 125
Therefore, proton no. : 207 - 125
= 32
Proton number and electron number is always equivalent, so there are 32 electrons in the electron shells
Protons and neutrons are always located in the nucleus of an atom, and electrons are located in the electron shells which always move rapidly around the atom
The element which is referred is Lead(Pb)
