If atoms contain charged particles, why do they not have a charge? a. They have the same number of protons and electrons. b. Charge is locked away in the nucleus. c. They contain an equal number of protons and neutrons in the nucleus. ...
Why is it necessary to round empirical formulas to a whole number? Why don't electrons in atoms repel? How does molecular weight affect mechanical properties? What is the purpose of TMS? a) It is the reference standard used in NMR. b) It determines how many nonequivalent protons are i...
The number of protons in the nucleus of an atom determines what element it is, sothe number of protons is fixed. But, the number of neutrons can vary. Nuclei with the same number of protons but different numbers of neutrons are called isotopes. ... Chemical properties in general do not ...
(1913) Niels Bohr’s quantum model was also based on a planetary model, but here, the electrons revolve in paths with fixed energy called orbits. The spaces between the orbits are forbidden for the electron. This model rules out the spiraling of electrons into ...

Since uranium is a heavy nucleus, the protons are highly repelled from each other and more neutrons fit in-between them. This will give you a large n/p number. When uranium emits an alpha particle, it emits an equal number of protons and neutrons. At this point it becomes a simple ...
Because protons are positively charged while electrons carry a negative charge equal in magnitude to the proton's charge, the atom itself is neutral, as neutrons, befitting their name, have no charge. On the other hand, protons and neutrons are very similar in mass and occupy the center of ...
In this experiment, we are generating static electricity by rubbing plastic objects against human hair. The flow of static electricity happens only when there is an equal amount of protons and electrons on the surface or within the two solid materials. ...
- For finding the isoelectronic pairs, we can just add the number of electrons of each atom in the species and also the charge of the species (if present). - Then, if the number of electrons are equal in both species, they are said to be isoelectronic pairs. ...
What happens to electrons in any charging process? Insulators also contain electrons, but they are not conductors, Why? What is meant by flow of electrons? Why do electrons in insulators not contribute to its conductivity? Why are electrons, rather than protons, the principal charge carries in ...
