See atomic mass examples, learn the atomic mass definition, how to find the atomic mass of an atom, and the importance of atomic mass. Related to this QuestionWhat is the atomic weight of an element? An atom of an element weights 3.00 x 10^-23 g. What is the atomic mass of this el...
The atomic mass of an element is found by adding the number of protons and neutrons in an atom of the element. It can also be found somewhere underneath the symbol of the element in the element's box on the periodic table.Answer and Explanation: ...
In 1808, an English school teacher and scientist named John Dalton proposed the modern atomic theory. Modern atomic theory simply states the following. Every element is made of atoms—piles of paper clips. All atoms of any element are the same—all the paper clips in the pile are the same...

835 times more massive than an electron. Atoms always have an equal number of protons and electrons, and the number of protons and neutrons is usually the same as well. Adding a proton to an atom makes a new element, while adding a neutron makes an isotope, or heavier version, of that...
