What is the electronegativity for an ionic bond? Given the electronegativity values below, which of the following covalent single bonds is the most polar? Element Electronegativity H 2.1 C 2.5 N 3.0 O 3.5 (a) C-H (b) N-H (c) O-H (d) O-C (e) O-N Which molecule would be expecte...
The oxidation number of an element is the charge the element would have if the compound that it is a part of consisted only of ions. When the oxidation number of an element increases, it is said to undergo oxidation. When the oxidation number decreases, t...
Anhydrous ammonia plays an important role in farming, especially as a nitrogen fertilizer. Nitrogen is a critical element for plant growth and development. It makes up one-sixth of amino acids, the building blocks of proteins, and chlorophyll (the compound responsible for photosynthesis). Anhydrous ...
The central atom in ammonia (NH3), which is nitrogen, is the one that undergoes hybridization to give sp3 hybridised molecules. We will figure out the entire process in the article.

Which element`s 3^+ iron would have the electron configuration [Ar] 3d^10? What is the correct electron configuration for Se? What is the electron configuration of \left[N(CH2CH3)4\right]2CoCl4? and \left[Co(NH3)6\right]Cl3?
This small device can measure temperature, humidity, PM2.5, PM10, atmospheric pressure, light, noise, TVOC, CO2, formaldehyde, O3, CO, CH4, O2, SO2, NO2, H2, H2S, NH3, etc. It is a good choice for home or office. It is like the software we usually use. When an air element exce...
A molecule is a group of two or more atoms joined by chemical bonds, whereas a compound is a substance formed by the chemical bonding of more than one type of element that exists in a fixed proportion.
