ANSWER:Solution : Here, we need to fill the blanks of the table using the other data given in the table. An atom is the smallest particle of an element. Any atom of an element is made up of three subatomic pa rticles namely rotons, neutrons nd lectrons. These subatomic particles gives the element's atomic number and mass number. Protons a re p ositively charged particle, electrons gatively charged and neutrons a re neutral, which means there isno charge. In neutral state, an atom has qual number of protons and electrons. An atom’s atomic number gives number of protons a nd electrons. the sum of number of protons and neutrons gives the mass number of an atom. the difference of mass number and number of protons gives number of neutrons. Let’s consider a carbon(C) atom, to show the representation of atomic number and mass number. The following is the representation of atomic number and mass number of an element. Let’s consider all the atoms are in neutral state. Let’s consider the 1st set of data in the table, the symbol of the element is given as Br. We
