# How would you determine the total number of electrons found in an atom?

You would look up the atomic number, $Z$, of that atom.......
To a firat approximation all matter, and thus all elements, are neutral. $Z$, the atomic number, represents the number of positive, nucular charges; i.e. $Z = 1$, $\text{hydrogen}$, $Z = 2$, $\text{helium}$.......$Z = 23$, $\text{vanadium}$.
Of course, elements can form ions, with a net charge defined by the excess or deficiency of electrons with respect to the atomic number $Z$.
