Bohr-Rutherford & Lewis Dot Diagrams

Review: An atom is the smallest particle of an element which is still considered to be that element. electrons are located outside of the nucleus protons and neutrons are located inside the nucleus

Bohr-Rutherford Diagrams

Bohr-Rutherford Diagram – a visual representation of the arrangement of electrons around the nucleus of an atom.

Lets Draw Bohr-Rutherford Diagrams!

helium (2 electrons) Lets draw .... He 2P 2N

Lets draw .... fluorine (9 electrons) F 9P 10N

Lets draw... Aluminum (13 electrons) Al 13P 14N

Electron Arrangements

Electron Arrangements & Bohr-Rutherford Diagrams Valence Shell – the outermost electron shell Valence Electrons – the electron(s) that occupy the outermost shell valence electrons valence shell
