2. Drawbacks of Dalton's Atomic Theory
The indivisibility of an atom was proved wrong: an atom can be further subdivided into protons, neutrons and electrons. However an atom is the smallest particle that takes part in chemical reactions. According to Dalton, the atoms of same element are similar in all respects.

4. don't know
5. Atomicity refers to Total number of atom present in a one molecule of an element. Valency refers to the no. of electrons present in an outermost shell of an element. ... = According to electronic configuration of Na(sodium), the valency is 1 because it have 1 electron in an outermost shell.
