Subatomic model of matter - Study guides, Class notes & Summaries

Identify and explain the similarities and differences between atoms, molecules, elements, and compounds - Atoms: the smallest unit of ordinary matter that forms a chemical element Molecules: electrically neutral group of two or more atoms held together by chemical bonds. Elements: consists only of the same atoms, with the same number of protons Compounds: a chemical substance composed of atoms from 2+ elements held together by chemical bonds Make an argument(claim, evidence, reasoning) for...

Acid - Answer-Chemical substance whose aqueous solutions are characterized by a sour taste. Have a pH of less than 7. Amino Acid - Answer-An organic compound containing both NH2 and COOH groups. Proteins are polymers of this Adhesion - Answer-Binding of one substance or structure to another as in a cell binding to its extracellular Matrix Amino group - Answer-Consisting of a nitrogen atom attached by single bonds to hydrogen atoms, alkyl groups, aryl groups, or a combination of them Buff...

atom - correct answer the smallest particle of an element that retains its identity in a chemical reaction atomic mass - correct answer the weighted average of the masses of the isotopes of an element atomic number - correct answer the number of protons in the nucleus of an atom of an element group/column - correct answer a vertical column of elements in the periodic table; the constituent elements of a group have similar chemical and physical properties period/row - correct answer h...
