In proof compression, an area of mathematical logic, LowerUnivalents is an algorithm used for the compression of proofs. LowerUnivalents is a generalised algorithm of the LowerUnits, and it is able to lower not only units but also subproofs of non-unit clauses, provided that they satisfy some additional conditions. (Wikipedia).
Chemistry: What is a Covalent Bond? - Polar & Nonpolar - Intramolecular Forces
Practice Tests available at http://bit.ly/CHEMTESTS - 50 questions + Complete Answer Key Covalent bonds are one of the 3 main types of intramolecular forces, along with ionic bonds and metallic bonds. Covalent bonds are the result of atoms sharing their valence electrons. Covalent bonds ca

The four types of chemical bonds
Bonds can be either ionic, covalent, metallic, or secondary. They can also have mixed character of multiple types! What exactly do these mean? Ionic and covalent are both strong, but ionic is an exchange of electrons whereas covalent is sharing. Therefore, covalent remains directional (the
