You think probable to atomic number, equal to the number of protons in the atomic nucleus.
They are determined by the number of protons in their nucleus.
No. The properties of elements are determined by the number of protons, which in turn determines the number of electrons.
Every elements has atomic number, elements identity determined the number of protons in its nucleus.

An elements period is determined by the number of electrons it has in its outer shell.
the properties of elements are determined by the structures of their atoms.
On the Periodic Table of Elements, the order from top left to bottom right is determined by the atomic number of that element, which is determined by the number of protons that are present in the nucleus of that element's atom.
You need to clarify this question. Do you mean, "How is the number of protons determined in the periodic table of the elements?"
