Bohr - Rutherford basics
Who created the Bohr Rutherford Diagram?
Niels Bohr
What particles are in the nucleus?
Protons and neutrons
How do you find protons and electrons?
Look at the atomic number
What is a charged atom called?
An ion
What year was it created?
1913
What circles the outside of the nucleus?
Outer shells
How do you find neutrons?
You subtract the atomic number from the atomic mass
Why do atoms gain charges?
When their valence shell is unstable
What kind of diagram is it?
Visual
What's on the outer shells?
electrons
Where do you start placing the first electron on the second shell?
On the bottom of the shell and then you move up to the right.
What part of the atom can transfer during a charge?
The electron
What does the diagram represent?
The structure of an atom
How many electrons fill the first and second shell of an atom?
First shell 2 / Second shell 8
Where is the atomic number placed on the element symbol and where is the atomic mass placed on the element symbol?
atomic number - top / atomic mass - bottom
If an atom has 3 valence electrons, will it become an anion or cation?
A cation because its charge is +3
What else is shown in the diagram
How all of the parts are arranged and work
What's the outermost shell called?
The valence shell
What determines the group of an element on the periodic table?
The amount of valence electrons it has
If an atom has 8 valence electrons, will it become a cation or anion?
An anion because its charge is -2
