Draw a Diagram of an Atom

Draw a diagram showing the charges of each part of the atom.

Describe Proton Protons are positively charged particles found in the atomic nucleus. Protons were discovered by Ernest Rutherford.

Neutrons Neutrons are uncharged particles found in the atomic nucleus. Neutrons were discovered by James Chadwick in 1932.

Electrons 1.Electrons are negatively charged particles that surround the atom's nucleus. 2.Electrons were discovered by J. J. Thomson in 1897. 3.Electrons determine properties of the atom. 4.Chemical reactions involve sharing, loosing & gaining of electrons.

Nucleus 1.The nucleus is the central part of an atom. 2. It is composed of protons and neutrons. 3.The nucleus contains most of an atom's mass. 4.It was discovered by Ernest Rutherford in 1911.

Isotopes Atoms that have the same number of protons but different numbers of neutrons called Isotopes.

Example of Isotope http://education.jlab.org/glossary/isotope.html

What is Electron Configuration? Arrangement of electrons around the nucleus of an atom. It takes the order of 2:8:8:18. for the first four energy levels. Arrangement of electrons around the nucleus of an atom. It takes the order of 2:8:8:18. For the First four energy levels.
