The reason the atomic number determines the chemical properties of an element is that the number of protons also determines the number of electrons in an electrically neutral atom. This, in turn, defines the electron configuration of the atom and the nature of its outermost or valence shell. Th...
Yes and no. If you are talking about a sample of a single isotope of an element, the atomic mass number and the atomic mass are either very close or else the same. In introductory chemistry, it's probably fine to consider them to mean the same thing. However, there are two cases in...

An atom's electrons are found in orbitals around the nucleus. The atomic number definition is based on the number of protons in an atom. Protons are positively charged particles in the nucleus of atoms. The atomic number is based solely on the number of protons in an atom. In contrast, ...
periodic table, in chemistry, the organized array of all the chemical elements in order of increasing atomic number—i.e., the total number of protons in the atomic nucleus. When the chemical elements are thus arranged, there is a recurring pattern called the “periodic law” in their propert...

Scaling up the number of atoms or ions in optical atomic clocks enables better precision, but this is often accompanied by interactions that limit the accuracy. Here, the authors propose and discuss using a three dimensional Coulomb crystal of one thousand Sn2+ ions as an optical atomic clock ...
