The total number of protons and neutrons added together is called the relative atomic mass. Hydrogen has a relative atomic mass of 1, while helium's relative atomic mass is 4 (because there are two protons and two neutrons inside). In other words, an atom of helium is four times heavier...
What is the atomic number of an atom that has 6 protons, 6 neutrons, and 6 electrons? What is the atomic number of rubidium? What is the atomic number of oxygen? What is the atomic number of roentgenium? What is the atomic number of aluminium?

Atoms are the purest form of matter. They consist of protons, neutrons, and electrons. The periodic table lists all of the different types of atoms that are known to exist and are known as elements. Answer and Explanation: An atom that has more protons than electrons is called a cation. ...

than the number of protons, with this disparity becoming larger as atomic number increases. A hydrogen atom, for example, has a proton but no neutrons, while a helium atom has two of each. Tin, on the other hand, has 50 protons and 69 neutrons, while uranium has 92 and 146 ...
What is the atomic number of an atom that has 6 protons, 6 neutrons, and 6 electrons? What is the atomic number of oxygen? How can you find neutrons using mass number? What is the mass number of an isotope? What is the atomic number of a neutron? What is exactly equal to the tota...
For example, carbon-14 has 14 protons and neutrons. Since all atoms of carbon have 6 protons, the number of neutrons is 14 - 6 = 8. Ions are atoms that have different numbers of protons and electrons.Ionsindicated using a superscript after the element symbol that states whether thecharge ...
An atom is built with a combination of three distinct particles: electrons, protons, and neutrons. Each atom has a center nucleus, where the protons and neutrons are densely packed together. Surrounding the nucleus are a group of orbiting electrons. ...
