WebbFör 1 dag sedan · The sigma (σ) bonds are of the highest stability and are the strongest covalent bonds of all. Still, it is the presence of a single lone pair of electrons at the apex, which makes all the difference. The hybridization of nitrogen in ammonia (NH3) is sp3. WebbFör 1 dag sedan · Step 1: First take a molecule of NOCl. A nitrosyl chloride molecule consists of one atom of nitrogen, one atom of chlorine, and one atom of oxygen. Step 2: Now, we will find out the total number of valence electrons present in one NOCl molecule. To do so, have a look at the periodic table. Nitrogen has an atomic number of 7 and … how far away are you safe from a nuclear bomb
