WebThe number of protons present in an atom is defined by the element's atomic number. Therefore, every atom of tungsten contains 74 protons. Since an atom must have an overall neutral charge, the number of protons and electrons found within an atom of an element must be equal. Therefore, every atom of tungsten also contains 74 electrons. WebWhen we look at an atom, we find that it has the same about of protons as it does electrons. So, if we look at oxygen, we see that its atomic number is 8, meaning that it has 8 protons. We can also assume that it has 8 electrons. So, oxygen has eight positive particles plus eight negative particles. Think of this as 8+ (-8) or 8-8.
