Question

4. State the main points of contradiction of Dalton's atomic theory by the Modern Atomic Theory.
5. 'Atoms of the same element or different elements combine to form a molecule'.
Give two examples each of - a) atoms of the same element b] atoms of different elements
combining to form a molecule.​

Answer 1

Explanation:

4. Dalton's atomic theory says that matter is made up of indivisible particles called atoms. But the modern atomic theory contradicts it by saying that atom is a divisible particle that can be divided into protons,electrons and neutrons.

5. Diatomic Molecules -- A diatomic atom is composed of only two atoms, of the same or different chemical elements. Examples of diatomic molecules are O2 and CO. Heteronuclear Diatomic Molecules -- A heteronuclear diatomic molecule consists of two of atoms of the same element combined.

Answer 2

Answer:

4. State the main points of contradiction of Dalton's atomic theory by the Modern Atomic Theory

Explanation:

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 some element are similar in all respects..
