1. number of protons. Look at the atomic number. The atomic number is the number of protons in the nucleus of the atom. For example, Na will have 11.
What about electrons. The number of electrons in the neutral atom is the same as the number of protons in the nucleus. Therefore, the neutral Na atom will have 11 electrons. To make it +1 charged, one electrons is removed. If you take away a negative charge it leave a +1 ion. (11 + charge due to protons + (10 - charges dues to electrons = +1 charge on what is left.
