4 The Periodic Table consists of elements arranged in order of increasing atomic number.(a)(i) What is meant by the term atomic number?(1) A the number of neutrons in an atom B the number of protons in an atom C the number of protons plus the number of electrons in an atom D the...
Atoms of an element are all the same in terms of shape and size and atoms of different elements differ in size and shape. Elements are characterised by mass of their atoms so all the atoms of an element have identical weight. Different elements have atoms of different atomic weight. Atoms ...
Periodic Table of Elements - The periodic table is the tabular arrangement of all the chemical elements on the basis of their respective atomic numbers. In the periodic table, the vertical columns are called groups and the horizontal rows are called peri
