The correct description for atomic weight, atomic mass , mass number, atomic number , and molar mass should be determined. Concept introduction: Periodic table represents a systematic arrangement according to element’s physical as well as chemical properties. Here, elements are represented as a two-letter symbol and are arranged in increasing order of atomic number. Periodic table contains 18 groups (columns) and 7 periods (rows). In periodic table, groups from 1-2 and 13-18 are termed as main group elements. The 10 middle groups from 3-12 are termed as transition elements . There are also 14 elements that starts with lanthanum known as lanthanides and 14 elements started with actinium are known as actinides.
