Answer» Solution :(i) Period 3 of the periodic table consists of elementswhose atom has three she ll s occupied by electrons. (ii)As pe r the electron HOLDING capacity of shells ,2 ELEMENTS are present in the first period, and8 elements in the second period. (iii) The thi rd per io d also contain only eight elementsdue to the law of electron OCTET and also electronswill fill orbitals in increasing order of energy, i.e.the LOWEST energy orbital first. |
