How do Bohr Diagrams show this.
They show electrons orbiting the nucleus of an atom.
What are steps 1-3 of drawing a Bohr Diagram
Find your element on the Periodic Table
Determine the number of electrons
Draw a circle for the nucleus
What are steps 4-6 of Drawing a Bohr Diagram
In the nucleus circle write the number of protons p+
In the nucleus circle write the number of neutrons n0
Draw circles around the nucleus
What is the atomic number
Protons
What is the mass number
Neutrons
What are the circles around the nucleus called
Electron shells/ energy levels
What is step 7 of Drawing a Bohr Diagram
Add the electrons using a - to represent each electron
How many electrons can the first shell hold
2
How many electrons can the 2nd shell hold
8
How many electrons can the third shell hold
18
What are all the steps to drawing Nuclear Notation
Find your element
Determine the number of protons and neutrons
Write down the chemical symbol
In the top left corner of the symbol
In the bottom left corner of the symbol write the atomic number
