What is the atomic number of beryllium-9? What is the atomic number of the element lawrencium? What is the atomic number of carbon-12? What is the atomic number for tungsten? What is the atomic number of americium? What is the atomic number of helium-4?
The element with atomic number 4 is beryllium, which means each atom of beryllium has 4 protons. A stable atom would have 4 neutrons and 4 electrons. Varying the number of neutrons changes the isotope of beryllium, while varying the number of electrons can make beryllium ions. The symbol fo...
