write postulates of dalton atomic theory.
Answers
1) Every matter is made up of small particles,they are called atoms.
2) Atoms are indivisible particles that can neither be destroyed nor be created in a chemical reaction.
3) Atoms of a same element have identical mass as well as similar chemical properties.
4) Atoms of different elements have different mass as well as different chemical properties.
5) Atoms combine in the ratio of small whole numbers to form compounds.
6) The relative numbers as well as kinds of atoms are constant in a given compound.
Answer:
1- Atoms:
Matter is made of of small, indestructible and indivisible particles called atoms.
2- Identical:
Elements that consists same atoms due to which they are similar in alll aspects such as - shape,size,chemical featured etc.
3- Non-similar:
Elements that consists of different atoms due to which they are different in aspects such as-shape,size,chemical features etc.
4- Compound:
Atoms of different/same elements combine together to form a compound.
5- Smallest particle:
Atoms are the smallest particles that takes part in chemical reactions.
6- Conservation law:
Atoms can neither be created nor be destroyed.
7- Rearrangement:
Chemical reactions involve combination,seperation and rearrangement.
