Atomic number, the number of a chemical element in the periodic system, whereby the elements are arranged in order of increasing number of protons in the nucleus. Accordingly, the number of protons, which is always equal to the number of electrons in a n
Well, as you know, an atom consists of electrons, protons and neutrons. The number of electrons in the outermost shell gives us the valency of the atom. Similarly, the number of protons and neutrons are associated with the atomic number and mass number of the atom. ...

The atomic number of an element can be described as the number of protons present in the nucleus of each atom of that element. Let’s explore it in detail. Atomic Number Definition The atomic number or proton number of an element is defined as the number of protons present in the nucleus...
Since atomic number is the number of protons in anatomand atomic mass is the mass of protons, neutrons, and electrons in an atom, it seems intuitively obvious that increasing the number of protons would increase the atomic mass. However, if you look at the atomic masses on aperiodic table,...
For most atomic nuclei, the maximum number of neutrons that can be bound is unknown. The discovery of two neutron-rich nuclei — and the confirmed absence of others — might help solve this conundrum. Stars are element factories. Every atom in the Uni...
