An electron is a negatively charged sub-atomic particle that is located in an atom along with protons and neutrons. The electrons are found in shells and sub-orbitals that surround the nucleus of the atom. More » Science Chemistry Atoms & Molecules

In most atoms, electrons occupy a zone exterior to the nucleus. Though electrons are often represented as particles in discreet orbits around the nucleus, they cannot be said to occupy a specific point in space. Rather, ... More »

Electrons are found in parts of an atom called shells that cover different energy levels and are referred to by the letters K, L, M, N, O, P and Q. More » Science Chemistry Atoms & Molecules

The size of an atom is dependent on the type of atom the number of protons, neutrons and electrons it contains. Each atom on the periodic table has a different size. More »

The three parts of an atom are the protons, neutrons and electrons. Atoms make up the basic building blocks of matter and define the structure of elements. These parts were not officially identified until 1932. More »

To draw a Bohr model of an atom, first find the number of protons, neutrons and electrons in the atom from its atomic weight and atomic number. After that, place the neutrons and the protons in the nucleus, and draw the ... More »

The three components that make up an atom are protons, electrons and neutrons. Protons possess a positive electrical charge, electrons are negatively charged and neutrons have no electrical charge at all. More »
