(a)
Interpretation:
Physical property, ductile has to be classified whether it is for metallic elements or nonmetallic elements.
Concept Introduction:
Metals are elements that have characteristic properties of thermal conductivity, luster, electrical conductivity, and malleability. Except mercury, the physical state of all other metals is solids. They have very high melting points and high density.
Nonmetals are elements that are characterized by the absence of properties like thermal conductivity, luster, electrical conductivity, and malleability. Mostly nonmetals are gases. Only bromine is present as liquid in room temperature. The density of nonmetals is low and they have lower melting points than metals.
In the periodic table, a total of 23 elements are nonmetals. The metallic property of the elements decreases as moving from left to right across the period in a periodic table. The elements that are present in right side of the periodic table are nonmetals.
(b)
Interpretation:
Physical property, low electrical conductivity has to be classified whether it is for metallic elements or nonmetallic elements.

Your instructor will give you 2 amino acids during the activity session (video 2-7. A. First color all the polar and non-polar covalent bonds in the R groups of your 2 amino acids using the same colors as in #7. Do not color the bonds in the backbone of each amino acid. B. Next, color where all the hydrogen bonds, hydrophobic interactions and ionic bonds could occur in the R group of each amino acid. Use the same colors as in #7. Do not color the bonds in the backbone of each amino acid. C. Position the two amino acids on the page below in an orientation where the two R groups could bond together. Once you are satisfied, staple or tape the amino acids in place and label the bond that you formed between the two R groups. - Polar covalent Bond - Red - Non polar Covalent boND- yellow - Ionic BonD - PINK Hydrogen Bonn - Purple Hydrophobic interaction-green O=C-N H I.
