The single most important characteristic of an atom is its atomic number (usually denoted by the letter Z), which is defined as the number of units of positive charge (protons) in the nucleus. For example, if an atom has a Z of 6, it is carbon, while a Z of 92 corresponds to ...
How do you show the number of protons and neutrons on a Bohr-Rutherford diagram? How does an atom try to fill its valence shell? How do you find the valency of an element? How can one find the valency of an element? The atomic mass of the element is determined by the...
does not correspond to the microscopic mass. the macroscopic mass implies a certain isotopic distribution while microscopic refers to the mass of the most common isotope of oxygen that is o-16. remember the macroscopic mass is also called molecular weight or atomic weight. how to find isotopic ...
