Any 2 postulates of Dalton's atomic theory?

Question

Answer

Matter is small particle of atom. Matter is cannot be created or destroyed and matter is always consist of mass of proportion

Answer

1)Atom is the smallest particle of matter which can't further divide ....2)atoms can't be created and can't be destroyed ,,,,,,,,,3)atoms of different elements have different physical and chemical properties,,,,,,,,, 4)all atoms of particular element have unique properties with unique mass ,,,,,,5)atoms of different elements combine in a fixed ratio, to form cmpounds ,,,,,6) in chemical reactions there is reorganisation of atoms

Answer

Pls answer fast

Answer

•all matter made up of indivisible particles called atoms•atoms cannot be created or destroyed•atoms of same element are similar in shape and size

Answer

All substances r made of small tiny particles called atoms atoms r neither created nor destroyed  law of constant proportion is followed

Answer

Answer

Atom is the smallest particle of matter.....and atom can't be created or destroyed....

Answer

Postulate 1: Matter is Composed of Atoms
- Dalton proposed that all matter is made up of tiny, indivisible particles called atoms.
- These atoms are the fundamental building blocks of matter and cannot be created or destroyed in chemical reactions.
- This idea laid the foundation for modern chemistry, emphasizing the atomic nature of substances.
Postulate 2: Atoms of the Same Element are Identical
- According to Dalton, all atoms of a specific element are identical in mass and properties.
- This means that each element has its unique type of atom, which distinguishes it from other elements.
- The implication of this postulate is that when elements combine to form compounds, they do so in fixed, simple ratios, highlighting the consistency of chemical behavior among atoms of the same element.
These postulates were revolutionary and shifted the scientific perspective on matter, leading to the development of the modern atomic theory. Dalton's ideas provided a systematic framework for understanding chemical reactions and the composition of substances, paving the way for future discoveries in chemistry.

Answer

1.Each element is composed of extremely small particles.
2.Atoms of one element are differ from the atoms of another element.
3.Atoms are indestructible i.e., they can be neither created nor destroyed.
4. Atoms of similar or dissimilar element combine in a fixed ratio by weight.
5.Atom is the smallest unit of matter which takes part in a chemical reaction.
