What is the three parts of Dalton's atomic theory?

Answer 1

There are five parts to The Atomic Theory:

1.All matter is composed of extremely small particles called atoms.

2. Atoms of a given element are identical in size, mass, and other properties; atoms of different elements differ in size, mass, and other properties.'

3.Atoms cannot be subdivided, created or destroyed.

4.Atoms of different elements combine in simple whole-number ratios to form chemical compounds.

5.In chemical reactions atoms are combined separated or rearranged.

Answer 2

John Dalton was a chemist known for curiosity when it comes to the weather and atmosphere, thus giving birth to his atomic theory. DaltonÕs atomic theory can be divided into 4: Every matter in the world are made of atoms, atoms of an element are similar in properties and mass, a combination of two or more kinds of atoms forms compounds and a rearrangement in atom is called a chemical reaction.

Answer 3

The main parts of dalton's atomic theory were:-

1st- It states that atom is indivisible.

2nd- It says that atom is of watermelon shape where seeds of watermelon shows neutrons and outer layer shows positive sphere which are equal in magnitude, so as whole atom is nuetral.

Answer 4

1) All matter is made of atoms. Atoms are indivisible and indestructible.

2) All atoms of a given element are identical in mass and properties

3) Compounds are formed by a combination of two or more different kinds of atoms.

4) A chemical reaction is a rearrangement of atoms.

Answer 5

1. All matter is composed of small indivisible particles called atoms.
2. Atoms of the same element are identical in size, mass, and other properties.
3. Chemical reactions involve the rearrangement of atoms to form new compounds.
