What is microwave?
300
Name this model:
What is the planetary model? (Will accept Bohr model for 150 points.)
300
The scientist who discovered the electron.
Who is J. J. Thomson?
300
Number of electrons:
2760Co
What is 27 electrons?
300
The nuclear particle that consists of a helium nucleus.
What is alpha particle?
300
This color of the rainbow has the highest amount of energy.
What is violet? (Purple also acceptable.)
400
Name of this model:

What is 46 neutrons?
400
Balance the nuclear reaction:
What is 1842Ar ?
400
Describe what must occur for an electron to jump to a higher energy level and what happens after.
An electron must absorb energy to jump to a higher level and it will eventually fall back down, releasing light in the process.
500
The most current model of the atom - name and who discovered it.
What is the quantum mechanical model discovered by Erwin Schrödinger?
500
The reason the electron was discovered.
What is because it has a negative charge and therefore can be deflected or attracted?
500
Number of electrons:
3888Sr+2
What is 36 electrons?
