Best Answer. Nitrogen has an atomic number of 7; that means that every atom of nitrogen has seven protons. (If the atom had more or fewer protons, it wouldn't be nitrogen, it would be something ...
The atomic number 46 indicates the number of protons in the nucleus of an atom. In this case, the element with atomic number 46 is Palladium. It is a transition metal with 46 protons in its ...
If you mean looking at the next element on the table then the mass would increase. However, the atomic number is only the number of protons in an atom and is not a true indicator of atomic weight.
The atomic number for sodium is 11, which means that sodium has 11 protons in its nucleus. This defines sodium as an element and determines its unique chemical properties.
Atomic Mass and mass number are differernt because atomic mass mean mass of whole atom which mean mass of proton,neutron and electron while mass number is number of proton and neutron only.zahid ...
It is called the "nuclear model" Rutherford concluded that. 1. Atom is mostly empty space. 2. Atom has a nucleus at its center. 3. Electrons surround the nucleus
Yes. The number of protons in the nucleus of an atom is equal to the atomic number. The idea of "atomic number" arose historically when trying to order the atomic elements. Henry Moseley is given ...
Best Answer. The number 15.999 is the average Atomic Mass of oxygen. It represents the weighted average of all the naturally occurring isotopes of oxygen, taking into account their relative ...
