State Dalton's atomic Theory of matter
Answers
2. atoms are individually particles which cannot created and nor be destroyed in chemical reaction.
3. atoms of a given elements are indentical in mass and chemical properties .
4.atoms of different elements have mass and their chemical properties.
5. atoms combined in ratio of small whole number to form a compound .
6.the realitive number and kinds of atoms are constantly in a given compound .Hope !this answer will help you.
and Plzzzzz mark this answer as brain list to increase my rank.
Dalton is a scientist who formulated certain postulates to define structure of atom....
His postulates are:
1.Each element is composed of extremely small particles called atoms.
2.Atoms of all given element are identical,the atoms of different elements are different and have different properties.
3.Atoms are neither created not destroyed in chemical reactions.
4.Compounds are formed when more than one element combine, a given compound always has the same relative number and kind of atoms.
5. When elements combine together they always combine in ratio of whole numbers
6.Atoms of a single element may combine in different ratios when they form more than one compound
7. An atom is the smallest particle that takes part in chemical reaction.
But his theory was discarded due to certain discoveries made later.
Foe ex:The first postulate was discarded when they found sub atomic particles like protons,electrons and neutrons
Hope this helped !!!! ..
