Sigma and pi refer to the symmetries of the chemical bonds. The symmetry is the "same" as an s orbital.
A sigma bond runs down the "axis" the orbitals that form it are two s orbitals or two axial p orbitals (usually called pz) or a pz and an s.
The pi bond has the same symmetry as the p orbitals - a positive lobe and a negative lobe.
Sorry about the explanation- its difficult to explain without getting into group theory.
It depends really which kind of bonding you're talking about. If your talking about ionic, covalent and hydrogen bonds here are some examples but don't exactly use these: Ionic Bonding An ionic bond is like a boy and girl. Covalent Bonding A covalent bond is like playing with a ball. Hydrogen Bonding Hydrogen Bonding is like picking lab partners. -From a fellow student working on the output on 14L.......
ACS Reagent grade is a designation given by the American Chemical Society (ACS) to chemicals that meet specific purity and quality criteria for use in analytical chemistry and laboratory applications. When a chemical is labeled as ACS Reagent grade from Sigma Aldrich, it means that it has been tested and certified to meet the standards set by the ACS for analytical reagents.
Chemical reaction involve only the bonding between atoms- no atomic nuclei are affected. The law of conservation of mass in chemistry perhaps should be called the law of conservation of atoms!
It's a line of cleaning products that guarantee that after use of the product that there will not be any odor left on the object of choice. It does this by using chemical bonding of their molecules with the molecules that give a bad odor.
Chemical- the composition of the substance Physical- appearance of substance
The XeO4 molecule uses sp3 hybrid orbitals from xenon for sigma-bonding. This allows xenon to form four sigma bonds, each with one oxygen atom in XeO4.

A chemical bond is an attraction between atoms that allows the formation of chemical substances that contain two or more atoms.
Some people also use the term "team bonding."
Chemical bonding occurs when atoms share, donate, or accept valence electrons to achieve a stable octet configuration. Valence electrons are the outermost electrons of an atom that are involved in bonding with other atoms, determining the atom's chemical properties.
Calcium only has two valence electrons to use in bonding...so it can't use three.

To build a compound from a chemical formula, first identify the elements present in the formula. Then, determine the ratio of each element in the compound. After that, use this information to arrange the atoms in the correct structure following the rules of chemical bonding.
