Bookmark or Share- Properties of ionic, covalent, and metallic compoundsIonic compounds tend to be crystalline structures with high melting points that are water soluble. Covalent bonds are highly stable bonds with low melting points. Many covalent compounds are flexible or gaseous and are not water soluble. Metallic compounds contain freely floating electrons which allow them to conduct electricity and heat well.
- How do you count pi electrons in aromatic compounds?pi bonds are simply the second bond made in a double bond. Any pure double bond is one sigma/sigma and one pi/pi bond. Since any one chemical bond (meaning only one line in bond line notation) contains at most two electrons, you can count two pi electrons per double bond, and ignore the sigma electrons. If you see lone pairs, consider the molecular geometry, and only the pi electrons that are ...
- What are alkanes, alkenes, and alkynes? + Example - SocraticBefore understanding each of these 3 types, you need to know that alkanes, alkenes & alkynes are hydrocarbons . Hydrocarbons are organic compounds which only consist of carbon (C) and hydrogen (H) as their elements. Alkanes are a group of acyclic, saturated hydrocarbons. These are contain carbon - carbon (C-C) single bonds. The single bond is made up of one sigma (sigma) bond. Their general ...
- What is an atom, element, molecule, and compound? What is an ... - SocraticAtom is a particle of matter that characterizes a chemical element. An atom is a particle of matter that characterizes a chemical element. It is the smallest part of ordinary matter. It is made from particles called protons, neutrons and electrons called the subatomic particles. An element is a substance that is made entirely of one type of atom. For example, the element sodium is made up of ...
- -ide and -ate, how do you know which one to use? - Socratic-ide: used when the anion is monoatomic. -ate: used when the anion is polyatomic (but still depends on the oxidation state of the ion) In naming ionic compounds, the name of the metal cation (positively charged) usually goes first followed by the name of the nonmetal anion (negatively charged). The suffix -ide is only used if the nonmetal anion is monoatomic (meaning one atom). e.g. chloride ...
