Some elements, like carbon, silicon, germanium, tin, and lead, have four electrons in their outermost shell. This means that they can gain four electrons to form M4+ or M4- ions, which can be ionic or tetravalent covalent. These...

This lesson will discuss the rules for writing the names and chemical formulae of covalent molecules and covalent networks. Definitions included: compound, ionic compound, covalent compound, covalent bond, electronegativity, molecular...

Delta-Aminolevulinate Synthase (ALA Synthase): Physiology, Biochemistry, and Organic Mechanism

It explains occurrence, electronic configuration, atomic and ionic radii, ionization enthalpy, physical and chemical properties of GROUP 16 elements.

With the main-group elements covered, it's time to check out the other sections of the periodic table, those being the transition metals, as well as the lanthanides and actinides. We rarely discuss most of these elements, so what are...

It discusses the trends of chemical properties such as oxidation states, chemical reactivity.

It's time to check out Group 15 on the periodic table, the pnictogens. This includes nitrogen, phosphorus, arsenic, antimony, bismuth, and moscovium. What can we say about their properties, reactivities, and applications? Let's find out!
