When given a word problem, how do you determine the numerator and denominator of constant of proportionality? How do you show the number of protons and neutrons on a Bohr-Rutherford diagram? How do you to convert polar to rectangular coordinates?
2\. Above the symbol is the atomic number (Z) which is equal to the number of protons in the nucleus and the number of electrons in the electron cloud (given that the atom is neutral). For carbon Z=6. 3\. Below the symbol is the atomic mass. While this number is a weighted aver...
Light stick activation occurs by simply cracking a light stick and allowing the chemicals to mix. You see glow-in-the-dark stuff in all kinds of places, but it is most common in toys. My son, for example, has a glow-in-the-dark yo-yo, a glow-in-the-dark ball, a glow-in-the...
There are holograms on most driver's licenses, ID cards and credit cards. If you're not old enough to drive or use credit, you can still find holograms around your home. They're part of CD, DVD and software packaging, as well as just about everything sold as "official merchandise...

How does an atom try to fill its valence shell? If you know the atomic number and the mass number of an isotope of an element, how can you determine the number of protons and neutrons? Explain the concept of the mole. How many electrons does aluminium have? Calculate the number of mole...
Today, some scientists question the validity of the story. They argue, for example, that the wooden horse may have been a battering ram used to break down the gates of Troy. But oral historians, who apparently wanted a grander tale to tell, altered the facts and injected the idea of an...
Here's an easy way to tell if the lenses in a pair of sunglasses are of good quality. Find a surface with repeating lines, like a tiled floor. Hold the sunglasses a short distance away from your face and cover one eye. Look through one of the lenses at the lines while moving the ...
