Feb 3, 2023 · This is one of the reasons why chemistry is interesting (certainly far more so then the physics of isolated neutral atoms). Many of the most interesting properties of water (H2O, just three atoms) arise because the electrons are unevenly distributed giving the molecules an uneven field that causes major intermolecular interactions that are ...

Oct 20, 2013 · Hence an atom is neutral. The reason why your doped semiconductor carries a neutral charge is because it has equal number of electrons as there are protons, be it boron doped or phosphorous doped. While the whole crystal remains neutral, by doping you are vastly increasing the conductivity of the semiconductor.

The p-type and n-type semi conductors are formed when the impurity atoms, which themselves are electrically neutral, are added to pure semiconductor which is also electrically neutral. Hence the p or n-type semiconductor formed is electrically neutral.

Jan 30, 2025 · Pure sodium is an electrically neutral metal. Adding an electrically neutral metal to an electrically neutral solute produces an electrically neutral mixture, because total charge is conserved. Some fraction of water is naturally separated into $\rm H^+$ and $\rm OH^-$ ions. When metallic sodium dissolves in water, ionized sodium atoms $\rm Na ...

This means that some specific parts of solution (even though it's small) to be not electrically neutral i.e. electrically charged. So I imagine in theory at least it must be possible to somehow extract these charge-rich areas and put them into a beaker. So what is all this I've been learning about solutions having to be electrically neutral?

May 29, 2015 · Think of a crystal of a material where the atoms have 4 valence electrons. Each atom has just as many electrons as protons and is neutral. Now replace one atom with a new atom of just one higher atomic number. This atom might have 5 valence electrons. It still has just as many electrons as protons and is neutral. But it doesn't fit.

Atoms are electrically neutral because they have equal numbers of protons (positively charged) and electrons (negatively charged). This also means the overall charge on the atom is zero. If an atom gains or loses one or more electrons, it becomes an ion.

Feb 21, 2022 · To our best knowledge, the observable universe is neutral. All evidence at hand suggests that the number of electrons in the universe is (almost) identical to the number of protons. If tis was not the case, the electromagnetic force, which is $\sim 10^{39}$ times stronger than the gravitational force, would dominate in the universe.

What is the net charge on the semiconductor when it is doped with; 1) N type semiconductor 2)P type semiconductor The answer for both cases is zero because it is neutral. But how it be neutral when it has excess electrons (when doped with n type) or holes ( when doped with p type) ??

Atoms are electrically neutral because they have equal numbers of protons (positively charged) and electrons (negatively charged). If an atom gains or loses one or more electrons, it becomes an ion. If it gains one or more electrons, it now carries a …
