Goldstein & chadwick atomic model

WebFive main points of Dalton's atomic theory: Elements are made of extremely small particles called atoms. Atoms of a given element are identical in size, mass, and other properties; atoms of different elements differ in size, mass, and other properties. Atoms cannot be subdivided, created, or destroyed. WebSolution: In 5626 Fe, atomic number (Z) = 26, mass number (A) = 56. Number of protons = number of electrons = Z = 26. Number of neutrons = A – Z = 56 – 26 = 30.
