If you were to look at grains of table salt (sodium chloride, NaCl) with a magnifying glass, you would see that each grain is a little cube. Why are salt grains cubical?

• A molecule of NaCl contains eight atoms, each at one of the corners of a cube.

• In the extended structure of NaCl, atoms are arranged in a cubical pattern.

• Sodium and chlorine atoms both have cubical shapes.

• All extended structure compounds form cubes.

Which biomolecule is found in pastas and breads? (Hint: it is a polymer)

• Lipid
• Protein
• Simple Carbohydrate
• Complex Carbohydrate

chemical bond

• the connection between atoms in more complex particles

• a structure whose subunits occur in a constant ratio and are arranged in a repeating pattern; the subunit can be individual atoms or a molecule

• a solid structure whose atoms or molecules are arranged in a repeating, three-dimensional pattern

• the types of elements that make up a substance, as well as the specific ratios of atoms of each kind of element that make it up
