Brainteasers for Physicists, Biologists, Chemists, Mathematicians and Other Crazy Brainiacs

You can imagine speeds of light, sound and falling objects without being a physicist, and you can envision the Earth’s vast biodensity of insects, birds and fish without being a biologist. You can grasp the infinitesimally small size of an atom and the gargantuan number of molecules you’d find in a drop of water without being a chemist; and you can fathom the immensity of large numbers and the enormity of the universe without being a mathematician. No problem, right?

And you don’t have to have any background to be interested in lightning, tsunamis, bubbles rising from ocean depths, giant worms boring through the Earth, the swing of a pendulum, the Big Bang, massive weights and startling Heights.

Chemical Bonds

Chemical bonds are lasting attraction forces between atoms that enable the formation of chemical compounds. However, there are four types of chemicals bonds including ionic, covalent, metallic, and hydrogen bonds. An ionic bond form when a metal loses electrons to become a positively charged cation, while the nonmetal accepts those electrons to become a negatively charged anion. As a result, there will be an attraction between those positive and negative ions, so we can conclude that ionic bonds are commonly formed between a metal and a non-metal ion.

A covalent bond is formed as a result of atoms sharing their outer layer electrons called valence electrons, in order to become stable by having a noble gas electron configuration. Continue reading Chemical Bonds
