Atoms consist of protons, which carry a positive electrical charge; electrons, which carry a negative charge; and neutrons, which carry no charge. Thus in an ordinary, electrically neutral atom, the number of protons and the number of electrons is equal. ...
Since atoms have no overall electric charge, each atom has an equal number of protons and electrons. For example, a nitrogen (N) has an atomic number of 7, so a nitrogen atom is made up of seven protons and seven electrons. Calculate how many neutrons the selected element is comprised ...
Many chemistry instructors teach beginning chemistry students the fundamentals of atomic structure by having them draw atoms based on the Bohr model of the atom. The Bohr model essentially treats atoms as miniature solar systems in which the small electrons orbit a much more massive nucleus, similar...

The atom calculator is a tool for calculating the atomic number and the mass number based on the number of atom components - protons, neutrons, and electrons (or vice versa). In addition, you can define the charge of ions with known numbers of protons and electrons. This article will provi...
The radius of an atom is described as the distance from its nucleus to its outermost electrons. Although it is impossible to know the exact position of these electrons, a very close approximation of the radius of an atom can still be determined by measur
Advertisement Step 2 Find and label protons. The protons are always in the nucleus, always have a positive charge (label them with a "P" or a "+"), and there are always the same number of protons as the atomic number of the element. Example: What is the atomic number of gold? It...
changes. This is not true of neutrons or electrons; variations of an element that contain different numbers of neutrons are calledisotopesof that element, whereas an element that has more or fewer electrons than it has protons is called anionand carries a positive or negative electrical charge. ...
