WebFeb 20, 2024 · Explanation: We know that a neutral oxygen atom has 8 electrons, which means that it has 2 electrons in the first shell and 6 electrons in the second shell, which is its valence shell. For O2−, it has gained 2 extra electrons, and so that will fill its outermost/valence shell, and will therefore have 2 +6 = 8 valence electrons. Answer link. WebNitrogen, the next nonmetal, has 5 electrons in the valence shell, so it needs to combine with 3 hydrogen atoms to fulfill the octet rule and form a stable compound called ammonia (NH3). This leaves two electrons that cannot be used for bonding (otherwise nitrogen would have to share more than 8 electrons, which is impossible). In the ammonia ...
Expansion of Octet Rule - Chemistry Guru
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? WebThe chlorine atom holds 7 electrons in its valence shell and can attain an octet configuration by gaining an electron. The outermost shell of sodium has one electron. If it … smackdown vs raw 2009 ds season mode

WebFeb 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. WebApr 8, 2024 · Developing cost-effective, efficient, and durable catalysts for oxygen evolution reactions (OER) is the key for promoting large-scale H2 production through electrochemical water splitting. Herein, we report a facile method for fabricating an NiFe@NiCr-LDH catalyst toward alkaline OER. The electronic microscopy technique revealed that it has a well … WebIn other words, it can be expressed as the neutral atom’s likelihood of gaining an electron. Note that, ionization energies measure the tendency of a neutral atom to resist the loss of electrons. Electron affinities are more difficult to measure than ionization energies. Electronegativity of Oxygen. Electronegativity of Oxygen is 3.44. smackdown vs raw 2009 road to wrestlemania
