While drawing each bachelor or bachelorette, I have the students talk me through the drawing so their review is ongoing. Also, the discovery we make at the end of the lesson is priceless. Kids often wonder about the shape of the periodic table, and when we discover that our bachelors can...
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...
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...
electric rocket would use a reactor to create electricity like a small power plant. Myers believes NASA should invest in all of them because they have different advantages for space travel. But joining the Defense Department in this nuclear-thermal test project was wise to combine resources, he ...
Thus, for an electron and proton to combine together to form a neutron, energy, mass, or both must be added. Conclusion Electrons may occasionally enter the nucleus, but it is improbable for them to interact with protons to form a neutron. Several concepts expla...
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 i

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.
