Dalton assumed that all atoms of the same element are identical in all their properties. Explain why this assumption is not valid. What makes a carbon atom different from a nitrogen atom? How are they alike? Why do elements form compounds?
Dalton wondered why the heavier and lighter gases in the atmosphere did not separate as oil and water do. He finally concluded that the constituent【C1】___must exist in the form. of 【C2】___particles or atoms and that these【C3】___be completely mixed together in the【C4】___. This...
Dalton wondered why the heavier and lighter gases in the atmosphere did not separate as oil and water do. He finally concluded that the constituent (61) must exist in the form of tiny particles or atoms and that these (62) be completely mixed together in the atmosphere. This threw a new...
Dalton's atomic theories were the early basis of chemical compositions. Dalton has proposed four postulates involving atom: (1) that atoms are indivisible, (2) atoms of an element have identical properties, (3) atoms combine to f...
In science, students spend a lot of time learning the facts and formulas of science (e.g., how atoms combine) and relatively less on the general process of the scientific method. This problem-solving process applies to any field of inquiry. ...
It’s called an organic compound because it is made up of one long chain of carbon atoms. They provide living things with energy and can act as substances that are used for structure. When multiple carbohydrates combine they change to polysaccharide. 1164 Words 5 Pages Decent Essays Read More...
