Electronegativity values can help you determine if a bond between two atoms is likely to be covalent or polar covalent. In order to do this, you find the absolute value of the difference between the electronegativities of the two atoms. Based on this difference, the following table tells you...
You could then build up molecules by attaching the bonds between atoms. Thus, a hydrogen molecule, made up of 2 hydrogen atoms, could be H—H, each atom holding on to the other by its one bond. Sometimes more than one bond could he used to connect two atoms. Sometimes some of the ...
where C is carbon, H is hydrogen, O is oxygen and each hyphen is a chemical bond between the atoms. For clarity, the bonds of the three hydrogen atoms to the left carbon atom are not shown. The OH (O - H) group on the molecule is what makes it an alcohol. There are four types...
The short answer is to look at the periodic table. Bonds between elements in the first two columns and the second to last two columns are ionic...
Create double or triple bonds between the central and outlying atoms if the central atom's valence shell is not full and pairs of non-bonded electrons are nearby. Step 11 If the electron is an ion, add or subtract the number of electrons indicated by the charge from a non-bonded pair. ...
Magnetic methods which consist in measuring the decrease of saturation magnetization of nickel give the number of metallic atoms strongly perturbed by chemisorption. Dilution of group-VIII metal by alloying it with IB metals allow us to calculate the total number of the group VIII atoms which are ...
When energy is added topure silicon, in the form of heat for example, it can cause a few electrons to break free of their bonds and leave their atoms. A hole is left behind in each case. These electrons, called free carriers, then wander randomly around the crystalline lattice looking fo...

Bonds between atoms can break and reform, allowing the elements to perform some amazing chemical tricks. They combine to produce larger compounds, decompose to form smaller ones, or swap one element for another to produce a chemical with different properties. These dynamic interactions are happening...
How To Determine Partial Charges Last time we talked about how electrons are the “currency” of chemistry and every reaction is a transaction of electrons between atoms. That means that if we really want to understand a reaction, we have to understand where the electrons are (and aren’t)...
