The atomic mass unit (AMU or amu) of anelementis a measure of its atomicmass. Also known as thedalton(Da) orunified atomic mass unit(u), the AMU expresses both atomic masses and molecular masses. AMU is defined as one-twelfth the mass of anatomof carbon-12 (12C).12C is the most a...
How do determine the mass number of the element U not the atomic mass? The atomic number of an atom of an element is 17 while its mass number is 35. How many neutrons does the atom have? How do you find the atomic mass of an element?
1 The relative atomic mass of an element is always D A the mass of an atom of the element relative to z the mass of a carbon-12 atom. B the mass of an atom of the element relative to the mass of a hydrogen atom.□ C the weighted mean mass of an atom of the element relative ...
Numbered Mass: The atomic number of an element refers to the number of protons/electrons located in the nucleus of an atom of that element. The atomic mass is the sum of the number of protons and the number of neutrons. Answer and Explanation:1 ...
