Verified step by step guidance1
Identify the atomic number of tungsten (W) from the periodic table. The atomic number represents the number of protons in the nucleus of an atom.
Recall that in a neutral atom, the number of electrons equals the number of protons to balance the positive charge of the nucleus.
Look up tungsten's atomic number, which is 74, meaning it has 74 protons.
Since the atom is neutral, the number of electrons must also be 74 to balance the positive charge of the 74 protons.
Therefore, the number of electrons in a neutral tungsten atom is equal to its atomic number, 74.
