+1
1.673 x 10^-27
What charge does a neutron hold?
What is its mass?
0
1.675 x 10^-27
, What charge does a electron hold?
What is its mass?
-1
9.109 x 10^-31
What is a atom?
The smallest unit of matter.
Who were the first people to use the word "atom"?
The Greeks
What did John Dalton demonstrate?
That individual elements were comprised of entirely of the same type of atoms.
How did Dimitri Mendeleev advance Dalton's work?
By organizing the known elements into the periodic table. This demonstrated that elements
arranged in order of increasing atomic mass has similar chemical properties.
What did Ernest Rutherford give us?
