Elements Their Atomic, Mass Number,Valency And Electronic Configuratio - Cbse 9 Chemistry Ncert Solutions : An atom x has mass number 40 and atomic number 18.. 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. Sodium atom has notation as 11na23. You have learnt in the rutherford's model that the atomic number and mass number are represented on the symbol of an element. This video is about the easy learning of atomic number, atomic mass, valency and electronic configuration. The number of electrons in the outermost shell is called valence electrons and the it is important to know the atomic number and electronic configuration of an element to find its valency.

Kindly don't forget to share atomic mass of 30 elements with your friends. In atomic physics and quantum chemistry, the electron configuration is the distribution of electrons of an atom or molecule (or other physical structure) in atomic or molecular orbitals. Elements in the same group had the same 'valency' and similar chemical properties. Elements of this block contain unpaired electrons and are paramagnetic. (c) what is the use of valency?
