An elements period is determined by the number of electrons it has in its outer shell.
It indicates how many electrons are required to complete a full valence shell.
It determines its place in reactivity. Usually gasesous elements are the electron recipients, except when it's gaseous-to-gaseous reactions (like combustion which turns a hydrocarbon into carbon dioxide and water vapor) while the metals generally are the donors. A case in point is HCl and NaOH make NaCl in a aqueous solution.
it indicates how many electrons are required to complete a full valence shell
Yes. The number of electrons in an atom tends to balance the number of protons. However, some atoms have more or less electrons, meaning they are in an ionic, or charged form.
It indicates how many electrons are required to complete a full valence shell.
the charge on a mono-atomic ion is the same as the oxidation number, for a polyatomic ion the charge is the sum of the oxidation numbers of its constituent elements.
Protons are the positive charge electrons in atoms that make up elements.
Elements whose atoms have the same number of outer electrons have similar properties..

These are the chemical properties.
Atomic number is not related to oxidation number. If you want to find the atomic number of a particular element, all you have to do is find it on the periodic table of elements.
