In the previous post, we talked about the oxidation state and the rules for their determination. In short, you need to know, or have the table, for the standard oxidation states, and determine the unknowns. Keep in mind, … Read more
In this post, we will be drawing the Lewis structure, and determining the geometry and hybridization of AsF5. AsF5 Lewis Structure The first thing we need to do when drawing a Lewis structure is determine the total number of valence electrons … Read more
In any oxidation-reduction reaction, there is an oxidizing agent and a reducing agent as oxidation cannot occur with reduction and vice versa, reduction cannot occur without oxidation. The oxidizing agent takes electron(s) from the reducing agent, so we can also … Read more
In the previous post, we talked about atomic radii, and discussed the following periodic trends: Atomic radius decreases across the periodic table to the right. Atomic radius increases down a group in the periodic table. Radii of Cations … Read more
In a general definition, radius is a straight line from the center to the circumference of a circle or sphere. So, how do we define the atomic radius? The center of the atom is the nucleus, and we consider the … Read more
Effective nuclear charge (Zeff) is the nuclear charge an electron actually experiences. Let’s understand what this statement means. We know from basic physics that opposite electrical charges attract, and if we consider the hydrogen atom, it is fairly straightforward to … Read more
