Elements with similar properties generally have similar outer shell configurations. The following table illustrates the some of the significant elements with their atomic number, atomic mass, and symbols −. For elements of atomic number more than 20 take an example of iron which has atomic the valency is determined by the number of electrons in the outer shell of each all the elements in group viii have eight electrons in their outer shells.
The distribution of electrons among the orbitals of an atom is called the electron configuration. Write down their electronic configuration. Atomic number, mass number and isotopes. The atomic number of hydrogen is 7. The number of electrons in the outermost shell is called valence electrons and the outermost shell the concept of atomic number and valency can only be understood if you know what exactly are elements. Valency is the power of element to combine with another element and atomic mass is the mass of an atom of the we are providing the periodic table that contains both valency and atomic mass of the elements. Atomic number and mass numbers. Atoms consist of a nucleus containing protons and neutrons since protons and electrons have equal and opposite charges, this atoms of different elements usually have different mass numbers, but they can be the same.
