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___47___must exist in the form of___48___particles or atoms and that these must be completely mixed together in the___49___. This threw...

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. I suspect very few teachers point out that every...
Why do atoms react to one another instead of fusing together completely? Why is the periodic table organized the way it is? Why do elements in the same family generally have similar properties? Explain why the periodic table is arranged the way it is. ...
Why do noble gases rarely form bonds with other atoms? What is the most active group of nonmetals? When nonmetals bond with other atoms, what usually happens? What happens when metals combine with nonmetals? Why are covalent bonds directional while ionic bonds are not?
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...
What force keeps atoms together? THE STRONG FORCE—the greatest of the four forces! The strong forces oppose the electromagnetic force of repulsion between protons. Like ”glue” the strong force keeps the protons together to form the nucleus. The strong forces and electromagnetic forces both hold...

To Pauli, quantum physics was restricted to examining the attributes ofatoms as explainable by mathematics. In this, atoms are treated as dead matter. But how do the atoms and molecules that make us up combine to give us the ability to contemplate love, hate, death and the universe?
If you put a molecule of pure carbon dioxide together with hydrogen and oxygen atoms, you would soon find that these two would be attracted to each other due to their orbital radii around the nucleus of the carbon dioxide molecule.
