The protons, neutrons and electrons present in an ion are determined from a periodic table. The atomic number represents the protons in an element. The atomic mass minus the atomic number represents the neutrons. In a ne... More » Science Chemistry Atoms & Molecules

Each atom contains an equal number of protons and electrons; these particles will be equal in value to an element's atomic number. For example, the element gold, or AU, has an atomic number of 79, meaning it has 79 proto... More »

The element carbon contains six protons in its atomic structure. Carbon has six neutrons that exist with the protons, found in the nucleus of each atom of carbon. More »

An ion has an electrical charge because it either has more electrons than protons or it has more protons than electrons. Electrons, which are found in the shells of an atom, have a negative charge, while protons, found i... More »

One neutral atom of nitrogen has seven protons, seven neutrons and seven electrons. This element is found in group 15 and period 2 of the Periodic Table of the Elements. It has an atomic weight of 14.007 amu. More »

The three types of subatomic particles are protons, neutrons and electrons. Protons and neutrons live together in the nucleus and are called nucleons. Electrons orbit the nucleus in orbitals. More » Science Chemistry Atoms & Molecules

The Bohr model for nitrogen has a central nucleus with seven neutrons and seven protons, a first energy ring with two electrons and a second energy ring with five electrons. A more detailed version shows two electrons in... More »
