No. That's more or less right. The atomic table was more or less created by Mendeleev and represents a fairly well-represented "average" of how most atoms exist in nature. Atoms in the periodic table are given an Atomic Number based on how many protons they have. Because as a general rule protons cannot be transferred unless you have degradation or radioactive decay. Electrons should be equal to the amount of protons in a given system so they balance out and form a neutral charge. If there are more electrons than atoms, then the element is said to have a negative charge. If there are less electrons than atoms, then the element is said to have a positive charge.
When it comes to tendencies in reduction or oxidation, that usually deals with the status of the valence electrons. Usually one of the primary rules for Chemistry is the Octet Rule which states that every atom strives to have eight valence electrons filling their outer shell. There are some pre-conditions. Such as aufbau principle and other basic rules that I've forgotten which for the purpose of General Chemistry served to reinforce the idea that electrons should be together in pairs. Usually some systems with an odd amount of electrons will sacrifice their lone electrons to just ensure that the remaining valence electrons are paired together.
Valence electrons play a large part in the chemical properties of certain atoms: http://www.youtube.com/watch?v=eCk0lYB_8c0
To be truthful I'm not that much into science either. I'm just really into the explosions.
