Atomic Structure

What are the 3 major parts of an atom? Proton Neutron Electron

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

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

Mass of the Nucleus 1 cm sphere Nimitz Class Aircraft Carrier A 1cm sphere of tightly packed nuclei would weigh 133,000,000 tons! That is equal to fitting 1400 Nimitz Class Aircraft Carriers into the 1 cm sphere.

Describe Proton Protons are positively charged particles found in the atomic nucleus. Protons were discovered by Ernest Rutherford.. Experiments done in the late 1960's and early 1970's showed that protons are made from other particles called quarks. Protons are made from two 'up' quarks and one 'down' quark.

Describe Neutron Neutrons are uncharged particles found in the atomic nucleus. Neutrons were discovered by James Chadwick in 1932. Experiments done in the late 1960's and early 1970's showed that neutrons are made from other particles called quarks. Neutrons are made from one 'up' quark and two 'down' quarks.

Describe Electron Electrons are negatively charged particles that surround the atom's nucleus. Electrons were discovered by J. J. Thomson in 1897. Electrons determine properties of the atom. Chemical reactions involve sharing or exchanging electrons.

Describe Quark Believed to be one of the basic building blocks of matter. Quarks were first discovered in experiments done in the late 1960's and early 1970's. Three families of quarks are known to exist. Each family contains two quarks. The first family consists of Up and Down quarks, the quarks that join together to form protons and neutrons. The second family consists of Strange and Charm quarks and only exist at high energies. The third family consists of Top and Bottom quarks and only exist at very high energies.

Describe Isotope Atoms that have the same number of protons but different numbers of neutrons

Describe Isotope Example:
