are determined by applying VSEPR theory to the valence electron distribution at the central atom, based on its number of covalently linked terminal atoms and non-bonding valence electron pairs. The orbital hybridization describes the set of hybrid orbitals formed at the central atom to covale...
What is the N-terminal residue of the peptide AYSDG? a) glutamic acid b) glycine c) aspartic acid d) alanine e) none of these choices Amino Acids: In a given peptide name, one can easily speculate which amino acids are present...

It is now generally accepted that atoms are made up of three particles called neutrons, protons, and electrons. The neutrons and protons are found in the nucleus (center) of the atom and the electrons reside in a shell surrounding the nucleus. Neutrons are heavy particles, but they have no...
Why spend so much effort on simple two-terminal components? The combinatorics of voltage and current ratings are certainly a factor, but the more subtle reason is that capacitors aren’t really that simple. The schematic symbols we use to represent them are lies by omission for convenience, ...
Just like gels themselves, lithium batteries have one foot (terminal?) on the "solid-state" side of the line and the other on the "liquid electrolyte" side. Not all solid-state batteries use lithium, but most do; not all lithium batteries are solid-state, but many are. Some batteries ...
The dopant atoms have either more or fewer valence electrons than the semiconductor atoms, resulting in excess or deficiency of charge carriers. There are two types of extrinsic semiconductors: n-type and p-type. In n-type semiconductors, the dopant atoms have more valence electr...
An alternative method substitutes a hydrocarbon name’s terminal -e with the suffix-amine for the functional group −NH2. The largest group is chosen as the parent of secondary and tertiary amines, and the other groups are designated as substituents. Examples 1. CH3− CH2 − CH (NH2)...
subscript is used to denote the number of atoms in a molecule, such as H₂O for water. In programming, subscripts can be found in variable names or array indices, helping to distinguish different elements within a data structure. These are just a few examples of how subscript is used in...
Non-Terminal vs. Terminal Functional Groups: Functional groups found on organic molecules can be positioned in two general ways. Some types of functional groups, such as alcohols (-OH), Carboxylate Acids (-COOH) or aldehydes (-CHO), are always found on one end of the molecule and so we ...
