Describe how two isotopes of nitrogen differ from two nitrogen ions. How do a 2px and a 2py orbital differ? How do ions form ionic bonds? Explain how to determine how and if atoms have valence electrons. What d
What occurs when an atom loses an electron? To become a positive ion, does an atom lose or gain an electron? How do you predict the charge of an ion? Explain how you determine the number of electrons that will go on the valence shell of an atom. ...
Your child will need to write a short essay in English, based on an age-appropriate topic. These topics are open-ended to allow for discussion, description and comparison. For example: Describe your ideal day. Schools shouldn’t have a uniform. Do you agree? If you won the lottery, what...
You can describe all of the interactions between the object and reference beams, as well as the shapes of the interference fringes, using mathematical equations. This makes it possible to program a computer to print a pattern onto a holographic plate, creating a hologram of an object that doesn...
You can get the whole story on lasers in How Lasers Work, but we're going to cover some of the key concepts here. Laser is an acronym for "light amplification by stimulated emission of radiation," which is a tongue-tying way to describe light in which the photons are all at the same...
He used the term "dark matter" to describe the unidentified mass required to cause this surge in velocity. How did scientists discover dark matter? When astronomers began measuring the rotations of spiral galaxies in the 1950s and '60s, they made a puzzling discovery. They expected to see ...
An objective of this work is to explore the extent to which 1D models can describe experimental data with a minimal set of meaningful parameters. Our parameters consider coarse-grained structural features and relate catch and slip bonds to specific force-induced conformational changes of the TCR–pM...
atom protein models – that these misfolded and native states have similar affinities for chaperones, indicating that chaperones do not treat these particular long-lived misfolded states much differently than they do the native state. The structural and energetic origin of this lack of differentiation ...
For me, however, there hasn't been a truly in-depth and reasonably simple cheatsheet which describe a variety of configurations and important cross-cutting topics for HTTP servers. Configuration of the NGINX can be tricky sometimes and you really need to get into the syntax and concepts to get...
The electrons have a charge and a mass, as well as a movement that physicists describe as spin in an upward or downward direction. Generally, electrons fill the atom's orbitals in pairs. If one of the electrons in a pair spins upward, the other spins downward. It's impossible for both...
