Where are valence electrons located?
The outside/outermost energy/ring of the electron cloud.
What is the overall charge of the electron cloud?
The overall charge of the electron cloud is negative.
There are only negative electrons located here.
Using APEMAN find the mass and neutrons for Oxygen?
Mass = 16 A.M.U. and Neutrons = 6
What is the largest number of energy levels on the periodic table?
7 periods
Explain what valence electrons determine?
How reactive an element is.
On the periodic table which group is considered stable? Why is it considered most stable.
Group 18
The elements in this group have 8 valence electrons in there outermost energy level.
What is the overall charge of the atom? Explain
The nucleus is considered to a overall neutral charge because the nucleus is positive and the electron cloud is negative.
