Finding the total number of electrons is easy. Assuming the atom is electrically neutal, the atomic number (always the number of protons) is also the number of electrons. This is because the protons are positively charged and the electrons are negatively charged, and a neutral atom will have a net charge of zero. Keep in mind, not all elements exist as atoms of their elemental state. Many of them are more commonly found locked up in compounds because they're just too reactive to exist solo.

What is the element with an electron configuration of 1s22s22p63s23p64s23d3?
Vanadium ( V) has that configuration. Its atomic number is 23.
What can the period of a element be determined by?
The period of an element in the periodic table can be determined by the number of electron shells or energy levels that the element's atoms have. Each period on the periodic table corresponds to the number of electron shells occupied by the elements within that period.
Does an electron determine what element it is?
The number of protons determine which element an atom is and normally the number of electrons is equal to it. Strip an electron off an iron atom and you have an ionised iron atom.
