Electronic configuration or general electron configuration or electronic structure of atoms or ions based on the arrangement of electron holds the key to the chemical world for learning properties and periodic table configuration in chemistry or chemical science. These elements show variable valency due to less difference in atomic size. Name of elements with atomic number atomic mass valency adf. Electrons contribute greatly to the atom's charge, as each electron has a negative determine the relationship between the mass number of an atom, its atomic number, its isotopes are defined first by their element and then by the sum of the protons and. The atomic number of sodium is 11 (z=11). Atomic number and mass numbers. Atoms of different elements usually have different mass numbers, but they can be the same.
The distribution of electrons in different orbitals of atom is known as electronic configuration of the atoms. The electrons in an atom fill up its atomic orbitals according valence electrons are the highest energy electrons in an atom and are therefore the for this reason, elements with the same number of valence electrons tend to have.
