Atomic Structure - Dalton's Atomic Theory
From Dalton's experiments and observations, and from the work of some of his colleagues he proposed a new theory of the atom.
Answer:
For answering we will have to create a 5x3 table. It will have the following headings:
The information that has to go in the table is:
Dalton's Postulates
1.1:All matter is composed of extremely small particles called atoms.
2.1: Atoms of a given element are identical in size, mass, and other properties. Atoms of different elements differ in size, mass and other properties.
3.1: Atoms cannot be subdivided, created or distroyed.
4.1 Atoms of different elements can combine in simple whole number ratios to form chemical compounds.
5.1: In chemical reactions, atoms are combined, separated or rearranged.
Keep/Modify/Discard:
1.2:Keep
2.2:Modify
3.2:Modify
4.2:Keep
5.2:Keep
Rewrite in case of need:
1.3: No need
2.3: Atoms of different elements differ in size, mass and other properties. Atoms of a given element can also differ in mass.
3.3: Atoms can be further subdivided, and using nuclearfission and fussion techniques atoms can be created or destroyed by changing them into other atoms.
4.3:No need
5.3: No need
