A Lewis structure is a graphic representation of the electron distribution around atoms. The reason for learning to draw Lewis structures is to predict the number and type of bonds that may be formed around an atom. A Lewis structure also helps to make a prediction about the geometry of a m...
Lewis structures provide you with a simple way to draw out an organic molecule showing every atom, bond, and lone electron pair. While not ideal for demonstrating bond angle and molecular geometry, it's a great way to begin your understanding of molecules and bonding in organic chemistry. Ever...
How and where did the Periodic table become in existence? Also, how has the periodic table been beneficial to science in a chemistry manner? Why is energy released when bonds are formed? Show how to make 1-chlorobutane from an acetylene. ...

Equivalent weight is defined as the mass of one equivalent of a given substance that will combine with or displace a fixed quantity of another substance. It's useful in chemistry because it can be used to make chemically different molecules with different mass equal. It measures mass (the amou...
How many unpaired electrons are present in the Lewis structure of a bromine atom? (a) 1 (b) 2 (c) 3 (d) 7. I need some help with these chemistry problems! How many orbitals in any atom can have the quantum number n=2?
are a graphical representation of the way electrons are distributed throughout a compound. Each element's chemical symbol is surrounded by lines, representing bonds, and dots, representing non-bonded electrons. When drawing an electron structure, your goal is to make each element's valence, or ou...
In this issue of Chem , Stephan and co-workers overturn long-held assumptions regarding the reactivity of frustrated Lewis pairs by providing compelling evidence that radical mechanisms might operate in some cases.doi:10.1016/j.chempr.2017.07.003Hamilton, Hugh B....
We propose explicit and implicit approaches for the teaching of acid-base chemistry based on research into the history and nature of science (NoS). To supp
Explain how you can use the electron configuration to determine whether the element Gallium would form a cation or an anion. Explain why beryllium forms an ion with a charge of +2. What does the octet rule in chemistry imply? What is the formal charge on ph...
