Atomic numbers, Mass numbers Atoms & PT_Diagramming Atoms Day 1 There are 3 types of subatomic particles. We already know about electrons (e–) & protons (p+). Neutrons (n0) were also shown to exist (1930s). They have: no charge, a mass similar to protons Elements are often symboliz...
mass number 1.The total number of protons and neutrons (nucleons) in the nucleus of an atom. 2.The number of nucleons (protons and neutrons) in the nucleus of an atom. Dictionary of Unfamiliar Words by Diagram Group Copyright © 2008 by Diagram Visual Information Limited ...
What is Atomic Number and Mass Number? Atomic number and mass number are always whole numbers because they are obtained by counting whole objects (protons, neutrons, and electrons). The sum of the mass number and the atomic number for an atom (A-Z) corresponds to the total number of ...

Therefore the mass number, as found in periodic tables, does not have to be an integer like the atomic number.According to Heisenberg's , it is impossible to know the electron's velocity and its position simultaneously. The exact position of the electron at any given time cannot be known....

Answer to: Draw the electron shell diagram of an atom with a mass number of 13 and an atomic number of 7. By signing up, you'll get thousands of...
The total number of nucleons in a nucleus (A) is known as the mass number. A nuclide has a particular nuclear composition with mass number A, atomic number Z and neutron number N. The notation we use to identify a particular nuclear composition of an atomic element E with atomic number ...
