An Atom consists of these main components
What are Protons, Neutrons, and Electrons
100
These short-range proton-neutron, proton-proton, and neutron-neutron hold the nuclear particles together in an Atom.
What are Nuclear Forces
100
What is an Isotope?
Atoms of the same element that have different that have different masses.
100
This is what amu stands for
Atomic Mass Unit
200
These tubes were used in an experiment in which the electron was discovered
What are cathode-ray tubes
200
These two parts of an Atom will always be the same.
Hint:They keep the Atom neutral
What are Protons and Neutrons
200
Protons and Neutrons are located in this.
What is the nucleus

True or False: Isotopes of the same element have the same mass number
False
200

6.02214179 x 10^23
300
This person was the first person ever to come up with the idea of an atom.
Hint: He was Greek

This is the outer area of an atom in which the electrons roam around in.
What is the electron cloud
300
Elements are ordered on the periodic table according to this
What are atomic numbers
300
This is a way that is used to specify between isotopes
Hint: Uses a hyphen
What is hyphen notation

What is a Mole?
The SI unit for amount of substance. Contains as many particles as there are atoms in exactly 12g of carbon-12.
400
This person led the experiment in which gold foil was used in the discovery of the Atomic Nucleus

500
This person led the experiment that discovered the electron
Who is English Physicist Joseph John Thompson
500
This is a nickname for the model of an atom
What is the "plum pudding" model
500
This part of the Atom is 1836 times greater then an electron
What is a proton
500
Daily Double!!!!!!!!!!!!!
If the answer to the question is right, your team could get double the amount of points for the question!

How is average Atomic Mass found?
Weighted average of the atomic masses of the naturally occurring isotopes of an element.
