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.

What is a simile for chemical bond?
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.......
What is ACS Reagent grade in Sigma aldrich company?
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.
How can you use the law of conversation of mass to help you balance a chemical equation?
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!
What does Zero Odor guarantee?
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.
What term would you use to classify the two substance?
Chemical- the composition of the substance Physical- appearance of substance
The XeO4 molecule can be said to use which type of Xe hybrid orbitals for sigma-bonding?
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.
Who was the first chemist to use the term covalent bonding?
Irving Langmuir in 1919.
What symbol would you use when automatically adding a set of numbers?
The capital sigma. The capital sigma. The capital sigma. The capital sigma.
How do you use bonding in a sentence?
A chemical bond is an attraction between atoms that allows the formation of chemical substances that contain two or more atoms.
What is another term for team building?
Some people also use the term "team bonding."
How can you use chemical bonding and valence electron in a sentence?
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.
Why is Ca 3 plus not found in chemical compounds?
Calcium only has two valence electrons to use in bonding...so it can't use three.
What kind of bonding to salts use?
Ionic bonding

How do you build a compound from the chemical formula?
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.
What is Six Sigma Healthcare?
