Niels Bohr and the Atomic Model Jennifer Meyer, Ed. S. Rutherford County Schools
The Basic Unit of Matter • Three states of matter: • Solid • Liquid • Gas Atom • Basic unit of matter • Has a nucleus • Has a cloud of negatively charged electrons
Parts of the Atom • Nucleus: center of atom • Neutrons: subatomic particles located in the nucleus of an atom with no charge • Protons: positively charged subatomic particle located in the nucleus of an atom • Electrons: negatively charged subatomic particles floating around the outside of the nucleus
Atomic number • The number of protons in the nucleus
Periodic Table of elements • Element: something that cannot be broken down into smaller units • Element: have the same number of protons in the nucleus
Periodic Table of elements • Dmitri Mendeleev • Russian chemist and inventor • Lived from 1834-1907 • First presented his periodic table in 1869
Bohr Atomic Model • In 1913 Niels Bohr introduced his model of the atom • Field of atomic physics • Bohr’s model studies the arrangement of electrons around the nucleus
