Properties of Atoms and Bonds Fill in the blanks. Every element has a unique number of _________, which if changed, would be a completely different element. Changing the number of _________ of an element by donating or gaining them results in an_______. A ________ results when an atom loses one or more electrons. An _______ results when an atom loses one or more electrons. _______ have no electric charge, and changing the number of neutrons in an element results in ________. The number of electrons in the ________ shell determines how an element will react chemically. Match the term to its definition and an example -a bond where electrons are shared unequally, creating partial positive and negative charges on the atoms -covalent bonds that join together amino acids in proteins by a Covalent Bonds dehydration reaction. -bond between hydrogen and oxygen within a water molecule Ionic Bonds -a weak attraction between a hydrogen atom and an electronegative atom atom. Polar Covalent Bonds -a bond where an exchange of electrons occurs due to one atom donating an electron, and the other accepting an electron. -a strong chemical bond where two atoms equally share Hydrogen Bonds electrons. -bonds present in the formation of NaCl (table salt) Peptide Bonds -bonds present in a polypeptide chain -bonding that is occurring in the secondary structure of protein -bonds formed in the molecule CCl4 Label the Diagram Below " This is a diagram of a ______ _______. (Count the protons and neutrons)  Macromolecules Worksheet Define the following -​ Macromolecules: -​ Polymers: -​ Dehydration synthesis/condensation reaction -​ Hydrolysis: -​ Isomer: Answer the following -​ Describe the differences between unsaturated and saturated fats -​ Where in lipids is energy stored? -​ Describe the differences between glycerol and fatty acids -​ How are lipids formed? What to know Nucleic Acids Fats (lipids) Proteins Carbs (carbohydrates) What are they made of?
