All elements in the periodic table are made of subatomic particles. These are protons, neutrons and electrons. The protons and neutrons are found in the centre of the atom, which makes up the atomic nucleus.Answer and Explanation: Become a member and unlock all Study Answers Try it risk-...
Atomic number Z represents the number of protons per atom. Mass number Z + N is equal to the number of protons Z plus the number of neutrons N present in the nuclei. Mass numbers of the most abundant isotopes are given in order of decreasing abundance. For example, Cadmium Cd-48 mass ...
Answer to: What two pieces of information do you need from the periodic table to help you determine the number of neutrons within an atom? By...

Atoms, the tiny particles that make up elements and combine to form functional molecules, are composed of three particles. Protons have a positive charge and are located in the nucleus of the atom, neutrons have no charge and are al...

The mass number of an atom is the total number of protons and neutrons contained within the nucleus of the atom. The number of protons determines the element and will always equal the atomic number of that element. The number of neutrons can change and will determine which isotope of that ...
