So protons and electrons are a bit like the two different ends of a battery: they have equal and opposite electric charges. Since an atom contains equal number of protons and electrons, it has no overall charge:
Why do atoms have an overall neutral charge? What would happen if OH-ions were added to a very basic solution? What is the electron configuration of the calcium ion? What is an example of the common-ion effect? Which type of ion channel opens ...
It works because these two different metals have atoms with different abilities to hold on to the electrons they contain. The zinc atoms in the nail lose their electrons (blue, e), which flow out through the circuit you've made to the copper atoms in the coin. This flow of electrons mak...
Explain the following: structure of atom, nuclei, and particles within atoms. How does a beta-minus (\beta-) particle compare with an electron in an orbital around the nucleus? a. The two particles have slightly different charges. b. The two particles have a slightly different volume...
for the negative charge at both of its carboxylate locations during the reaction, the reorganization energy can be reduced significantly. It appears that the reason why this major catalytic effect has not been revealed earlier for glucosidases, is that no comparisons to uncatalyzed water reactions ...
Why is anion larger than its parent atom ? View Solution Bryophytes have a life cycle with alternation of a haploid, sexual generation with a diploid, asexual generation. Unlike vascular plants, in bryophytes the ... is usually larger than the ……….. View Solution...
If we already have barcodes, why do need something else as well? 2D barcodes are a step further, with lots of advantages: More information: A barcode is just a short line of black and white bars so it can't contain much information: typically just a dozen digits or so—enough to ide...
For example, if you buy a smartphone, you don't simply do things on your phone that you used to do on your PC: you spend more time online overall, using apps and services that you previously wouldn't have used at all. Cloud computing made mobile devices feasible, so people bought ...
explain. which do you expect to have the larger dipole moment, H2O or OF2? explain Which molecule should have the higher dipole moment, and why? a) because it contains more F atoms. b) COFH because the polar bonds in nearly cancel each other...
Explain why each of these would work. Ksp Value: Ksp values are constants. They represent the level of solubility of a solid in a liquid phase. Overall, it is the equilibrium constant expressed in terms of multiples of the solubility of each...
