Answer :
The number of protons, neutrons, and electrons in an atom can be determined from a set of simple rules. The number of protons in the nucleus of the atom is equal to the atomic number (Z). The number of electrons in a neutral atom is equal to the number of protons.
Answer:
By finding the number of protons
Explanation:
Keep in mind when trying to find the number of electrons of a element, the number of electrons also equals the number of protons. In order to find the number of protons in the element simply find it's atomic number.
Example:
Find the number of electrons in the element iron.
Fe (Iron)
Fe's atomic number is 26
Protons/electrons = 26
Hope this helps.
