For example, hydrogen has 1 proton and 0 neutrons. Helium has 2 protons and 2 neutrons. Oxygen has 8 protons and 8 neutrons. Gold has 79protons and 118 neutrons.Outside the nucleus are electrons. They orbit the nucleus. Electrons have negative charges. But protons have positive charges. ...

1. The Elements and The Periodic Table(元素和周期表) The number of protons in the nucleus of an atom is referred to as the atomic number, or proton number, Z. The numbers of electrons in an electrically neutral atom is also equal to the atomic number, Z. The total mass of an atom ...
The lightest four elements are hydrogen, helium, lithium and beryllium. TL;DR (Too Long; Didn't Read) Hydrogen, helium, lithium and beryllium are the lightest four elements, with one, two, three and four protons, respectively. Hydrogen has no neutrons, helium has two, lithium has four and...

Since H-1 has one proton and no neutrons, its mass is 1. Because H-2 has one proton and one neutron, its mass is 2. Therefore, when you compute the percentages of the isotopes of H in any container, you find that the atomic mass of H is actually 1.0079. If the atomic mass of ...
That is elemental iron in the nuclei of neutrons and protons than all the other elements in the nuclei near the neutron and Proton, which more closely with proton-son of strong interaction strength is also one of the largest, therefore when its direction and at the same time, arranged in ...
Matter, including living matter, is comprised of elements. There are 118 recognized elements, 92 of which occur in nature. Elements consist of atoms of that element. Each element is unique because each element's atoms are unique, ...
The name indicates the mass of an atom, expressed in atomic mass units (amu). Most of the mass of an atom is concentrated in the protons and neutrons contained in the nucleus. Each proton or neutron weighs about 1 amu, and thus the atomic mass in always very close to themass (or nucl...
