Each element has a uniqueatomic number, which is the number of protons it has. This is how we identify one element from another. Theperiodic table of the elementslists all of the discovered elements and their atomic numbers. Examples of elements include oxygen (O), carbon (C), and gold (...
of protons in an atom is important, because it defines what chemical element the atom represents. For example, an atom with just one proton is hydrogen, an atom with 29 protons is copper, and an atom with 94 protons is plutonium. This count of protons is called the atom'satomic number....
This is because iron is an extremely stable element and stars aren't massive enough to trigger its fusion. When all nuclear fusion ceases, the star undergoes a final and catastrophic gravitational collapse. This triggers a supernova that flings the elements the star has forged during its life...
Protons have arelative massof 1, which is the same as the relative mass of neutrons. Thenumber of protons in an atomis called the 'Atomic Number' of that atom and is sometimes referred to as 'Z'. This is important because itdefines the type of atom, i.e. whichelementit is an atom...
Valence electrons are those electrons that reside in the outermost shell surrounding an atomic nucleus. Valence electrons are of crucial importance because they lend deep insight into an element’s chemical properties: whether it is electronegative or el

protons, neutrons, or alphas (two protons and two neutrons bound together). Some of these particles are known as ionizing particles. These are particles with enough energy to knock electrons off atoms or molecules. The degree of radioactivity depends on the fraction of unstable nuclei and how fr...
