atomic number - the order of an element in Mendeleyev's table of the elements; equal to the number of protons in the nucleus or electrons in the neutral state of an atom of an element baryon number - a number equal to the difference between the number of baryons and the number of anti...
atomic number(Z) a number expressive of the number of protons in an atomic nucleus, or the positive charge of the nucleus expressed in terms of the electronic charge. Avogadro's number(N) (NA) the number of molecules in one mole of a substance: 6.023 × 1023. Called alsoAvogadro's cons...

An element's atomic number directly correlates to the number of protons located in the nucleus of its atoms. In fact, the number of protons in the nucleus is the defining characteristic by which an atom is assigned its element. Answer and Explanation: ...

This is the number of protons in the nucleus of each atom. What is the atomic number of this helium atom? A neutral atom must have equal numbers of protons and electrons, so the atomic number of an element also gives the number of electrons. Helium has 2 protons, so its atomic number...
