When atoms have fewer than eight electrons, they tend … WebAtoms of oxygen have a total of 8 electrons. Are these atoms stable, and why or why not? a. No, because only atoms with 2 valence electrons are stable. b. No, because the atoms have only 6 valence electrons, but need 8 for stability. c. Yes, because oxygen is in the air we breathe and it doesn't hurt us. d. Yes, because the Octet Rule says ...

WebMay 5, 2024 · N-doped TiO2 with oxygen vacancies exhibits many advantages for photocatalysis, such as enhanced visible light absorbency, inhibition of the photogenerated charge carrier recombination, etc. However, preparation of N-doped TiO2 with oxygen vacancies under mild conditions is still a challenge. Herein, N-doped TiO2 nanospheres … WebOxygen is electronegative because it only needs 2 electrons to complete it's valence shell. Instead of losing an electron (like sodium, in sodium chlorine), it simply attracts to those 2 electrons. The more a atom wants an electron, the more electronegative it is and visa versa. To imagine whats more electronegative, simply look at the periodic ...

WebFrom the electron-in-box diagram we can see that oxygen has 2 unpaired electrons so can form 2 covalent bonds. In total oxygen will have 4 electrons from the 2 bonds and 4 electrons from its 2 lone pairs which adds up to 8 electrons. Hence oxygen is octet and obeys octet rule. How about sulfur, the Period 3 element directly below oxygen? WebFluorine is a second period element which can only contain a maximum of 8 valence electrons. Xenon meanwhile can have an expanded octet and can hold more than 8 electrons. Basically any of the fluorine atoms wouldn't be able to hold onto an extra 2 electrons which only leaves the central xenon atom with the ability to. Hope that helps.

Hydrogen has only one valence electron, but … predict one bizWebOct 1, 2014 · Oxygen wants to have 8 valence electrons so it takes 2 electrons from other elements when bonding. But, since Oxygen has 8 protons and now has 10 electrons around it, it has a charge of -2. I don't understand how having a charge is more stable than having no charge at all, shouldn't the most stable version of an element be its neutral state? predictone sonyWebApr 8, 2024 · When the atoms have less than 8 electrons they tend to react with other atoms and form more stable compounds. So, we can say that in an O 2 molecule, each oxygen atom is surrounded by a total of 8 electrons. But as we know, an oxygen atom has only 6 electrons in its valence shell. predictonics cincinnatiWebFeb 18, 2024 · Yes. While having an octet of valence electrons creates an exceptionally deep energy minimum for most atoms, it is only a minimum, not a fundamental requirement. If there are sufficiently strong compensating energy factors, even atoms that strongly prefer octets can form stable compounds with more (or less) than the 8 valence shell electrons. predictonlineWebThis is a problem because as a knowledgeable chemist you would automatically realize that there are 2 more electrons forming this molecule than can be accounted for by the atoms represented. In other words if we just count the valence electrons for the sulfur and oxygen shown we get a total of 30 valence electrons but we are showing 32 in the ... predict one 使ってみた
