Web19 okt. 2024 · Helium has two protons. Helium can be found on the periodic table at atomic number two. This number clearly shows you how many protons an element’s nucleus contains. The atomic number is specifically tied to a single element. What is the atomic mass of helium? Helium has an atomic mass of 4.00 atomic mass units. WebIn 1911, Ernest Rutherford discovered that at the core of every atom is a nucleus. Atomic nuclei consist of electrically positive protons and electrically neutral neutrons. These are held together by the strongest known fundamental force, called the strong force. The nucleus makes up much less than .01% of the volume of the atom, but typically ...
