Pre-Lab Exercise 2-3 Chemical Bonding One of the more challenging concepts to grasp in chemistry is chemical bonding, a topic that pops up again and again in A&P: We revisit it in cytology, the nervous system, blood, respiration, and digestion-to name just a few First let's do some basics. Use your textbook and this unit to answer the following questions 1. Do metals donate or accept electrons? What do they become after they donate/accept electrons? 2. Do nonmetals donate or...

Answer 1-4 (#3 and #4 are tables)
shell provides stability to the atom. Different chemical bonds are based on the way in which the atoms fill their valence shells. The major types of chemical bonds include: ionic bonds covalent bonds (both types, i.c. polar covalent and non-polar covalent bonds), and hydrogen bonds. Atoms can use two strategies to fill their valence shell: they can share electrons between their valence shells, or they can give or take electrons from other nearby...

Stick Notation for Organic Molecular Structures The molecular structure of (E)-B-damascone is represented below. In such shorthand diagrams, the end of each line segment, if not labelled with a chemical symbol, corresponds to a carbon atom. Hydrogen atoms bonded to carbon are frequently not drawn but are always inferred to complete the valence shell for each C atom. Non-bonding electrons for N and O atoms are also omitted from the diagram but can be inferred to complete those valence shells....

(A) the molecule will have a hydrogen bonded directly to an N, O, or F (B) the molecule will be nonpolar (C) the molecule will be an ionic crystal lattice structure where there are strong clectrostatic (D) the molecule will be polar 15 A substance with strong intermolecular forces will have (A) low boiling point (B) high reactivity...
