List
THREE
differences between protons, neutrons, and electrons that you have learned so far.
Question 14
14.
List any simularities you can think of between protons, neutrons, and electrons that you have learned so far.
What element is modeled here?
No element to see here... just be on your way. Again... nothing to see here.
ion
hydrogen
Lithium, I mean look... it has 3 protons, and Lithium is number 3 on the periodic table.
What is its charge right now?
No way to know based on the information we have. You're just going to have to tell me.
Well... it does have more neutrons than protons so the charge should be neutron.
negative
positive since there are protons with (+) charge, but it doesn't have any (-) charges
Use the simulation to balance the charge. (make the net charge zero)
What part of an atom has a negative charge?
its feet
protons
neutrons
electrons
Lithium has 3 protons (+) charges. How many electrons (-) must be added to make it neutral?

Electrons
are on the outer shells of an atom and
balance its charge.
In order for the charge to be
balanced
the number of
electrons equals the number of protons
.
True
False

How many electrons will be in a neutral atom of magnesuim?
12
24
at least 500
How many electrons will be in a neutral atom of chlorine?
HEY... that is in swimming pools... no way I'm swimming in electrons.

35
How many electrons will be in a neutral atom of neon?
neon is in lights... there should be plenty of electrons there

10
How many electrons will be in a neutral atom of potassium?
why did you have to make the last one so hard to find. Potassium is not P it is K... wierd.
