WebA water molecule consists of two hydrogen atoms bonded to an oxygen atom, and its overall structure is bent. This is because the oxygen atom, in addition to forming bonds with the hydrogen atoms, also carries two pairs of unshared electrons. All of the electron pairs—shared and unshared—repel each other. Web1. How many unpaired electrons are there in the Lewis structures of a N3- ion? Answer: There are 16 valence electrons for the Lewis structure for N3-. You should take formal charges into account with the Lewis structure for N3- to find the best structure for the molecule. Explanation: 2. what is the Lewis Dots Structure and Structural Formula ...

WebPolyatomic ions. In this article, we will discuss polyatomic ions. The prefix poly- means many, so a polyatomic ion is an ion that contains more than one atom. This differentiates polyatomic ions from monatomic ions, which contain only one atom. Examples of monatomic ions include \text {Na}^+ Na+, \text {Fe}^ {3+} Fe3+, \text {Cl}^- Cl−, and ... Web18 jun. 2015 · That means that around 76.85 % of the substance is nitrate ion. 20.0 g of the substance are equivalent to 20.0 g / 242 g m o l − 1 = 0.0826 m o l of F e ( N O X 3) X 3. Since roughly 76.85 % are nitrate ions, there are about 0.06 m o l of nitrate ions in those 20 g of substance.
