It can be shown as numbers or. 2, 8, 1 electrons are distributed in the shells k, l, m respectively. Atomic number, mass number and isotopes. These elements show variable valency due to less difference in atomic size. Atoms of different elements usually have different mass numbers, but they can be the same. These solutions are part of ncert question 2. Atomic number and mass number. Get the periodic table with electron configurations. 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. Sodium atom has notation as 11na23. For example, the mass number of argon atoms and calcium atoms can both be 40. (b) how is valency of an element determined?
