WebJohn Dalton (1766- 1844) He was an English chemist. When different types of atoms combine, they obey certain simple laws. Dalton’s atomic theory explains these laws in a simple way. He also gave a theory of colour blindness. Amedeo Avogadro (1776 – 1856) He made a brilliant guess that equal volumes of gases have equal number of molecules … WebSolution. The correct option is A. True. The above statement is true according to Dalton's atomic theory. But further discoveries on atom proved this theory wrong as atoms can be further subdivided into subatomic particles i.e atoms can be divided into electrons, protons and neutrons.

WebThe Dalton Atomic Theory is a model that explains the nature of atoms. It was developed by John Dalton in the early 1800s. The theory states that atoms are the smallest particle of an element that has the chemical properties of that element. Atoms are made up of protons, neutrons, and electrons. The number of protons in an atom determines the ...
