Isotopes of helium - Wikipedia

WebBoth neutrons and protons carry the strong force (but electrons do not). The strong force is what binds the nucleus together, by overcoming the repulsion between the protons. But an atom must have just the right balance of protons to neutrons to make a stable nucleus. If there are too few or too many neutrons, the nucleus won't be stable. WebThe nucleus of a helium atom is two protons and two neutrons. The mass of four protons is 6.690×10 –24 g. The mass of a helium nucleus is 6.643×10 –24 g, 0.7% lighter. What charge is a proton? Protons are found in the nucleus of the atom. This is a tiny, dense region at the center of the atom. atb bank atmWebAn atom is electrically neutral. If an atom gains or loses electrons, it will obtain a charge and become an ion. To determine the electrical charge of an atom or ion, simply count the number of positive protons and the number of negative electrons, then add these two numbers together. For example: the hydrogen atom has one positive proton and one … atb bandi

"WebAn atom which has 4 protons and 6 neutrons will be electrically neutral if it contains 4 electrons When an atom loses an electron, it becomes ionized An atom that has fewer electrons than protons is called a/an ion The loss of an electron from a neutral helium atom results in ionized helium " - How many protons does an atom of helium have
