Exercises do little good if they don’t have time to sink in.Finally,find the best time of day to do your studying.Don’t do it when you have many other things on your mind or when you are exhausted. Your mind has to be receptive for learning to take place....
As far as anyone knows, only elements with atomic numbers of 1 through 94 — hydrogen through plutonium — exist in nature1. Anything 95 and above has to come from a reactor or particle accelerator. During the early 2000s physicists at Russia’s Dubna facility began generating element 118, ...
An atom has electronic configuration 2, 8, 7. (a) What is the atomic number of this element ? (b) To which of the following elements would it be chemically similar? (Atomic numbers are given in parentheses.) N(71),F(9),P(15),Ar(18). View Solution An element has electronic...
Excellent question; it’s essentially a property of materials describing their ability to become electrically polarized in the presence of an applied electric field, through any of a number of mechanisms. These mechanisms might be at an atomic level, where the cloud of electrons surrounding the ...
Remember, an isotope is a form of a chemical element that has the same number of protons in its atomic nucleus but a different number of neutrons. The most common isotope of helium on Earth is helium-4, which does not have any known or potential uses as an energy source. Helium-3, in...
On an atomic level, dipoles occur due to non-uniform charge distribution. Consider an atom with a sea of electrons revolving around the central protons in fixed orbits but random order. Now, pause the scenario at any instant of time and select a pair of proton and an electron. ...
Platinum also may be found as a byproduct of processing other metals like nickel and copper. Most platinum is derived from a mineral called cooperite, also known as platinum sulfide. Platinum is even found in outer space. "Platinum has also been discovered in heavy concentrations in meteorites...
