WebIonic compounds are compounds composed of ions, charged particles that form when an atom (or group of atoms) gains or loses electrons. (A cation is a positively charged ion; an anion is a negatively charged ion.) Covalent or molecular compounds form when elements share electrons in a covalent bond to form molecules. WebIllustrate the importance of lone pairs for the hydrogen bonding, basicity and shape of amines. Know the structures of the amino acids, the formation of zwitterions and the meaning of 'isoelectric point'. Predict the products of hydrolysis of amides. Know the major factors involved in drug transport.

WebGases, liquids and solids are all made up of atoms, molecules, and/or ions, but the behaviours of these particles differ in the three phases. 13 Apr 2024 15:23:39 Web2.3: Atoms and Subatomic Particles. Define atom and subatomic particle. Describe the locations, charges, and relative masses of protons and electrons. Determine the number … WebAtoms consist of three basic particles: protons, electrons, and neutrons. The nucleus (center) of the atom contains the protons (positively charged) and the neutrons (no charge). The outermost regions of the atom are called electron shells and contain the electrons (negatively charged). Atoms have different properties based on the arrangement ... breinigsville pa post office
