An atom is the smallest unit of matter that cannot be broken down by chemical m means and an element Is a pure substance made of only one kind of atom. An element Is made up o f only one kind of atom. The atomic number and mass shows the amounts of that atom In proto ins, electrons, and neutrons. The atom Is the smallest unit of the element. 2) An atom is the smallest unit of matter that cannot be broken down and a molecule is a group of atoms held together by covalent bonds.
In a molecule there are atoms being brought HTH together to make a molecule. 3) In a ionic bond the atoms are brought together by the attraction of oppositely char De ions and an ion is when an atom or molecule that has gained or lost one or more electrons. A c bivalent bond Is sharing of two paired electrons together. There can one or more pairs In a co valet bond. 4) The type of weak bond that forms between water molecules is a hydrogen bond.
T he hydrogen bond is the attraction of two water molecules. 5) The difference between polar molecules and monopole molecules is that polar mole culls are molecules with an unequal distribution of electrical charge, such as water molecules. A monopole molecule is a molecule that shares electron equally and does not have ends with pop site charges. 6) Sodium chloride Is an example of a compound because It Is a substance made of t woo different elements. ) The difference between cohesion and adhesion is that cohesion is an attraction of molecules of the same substance and adhesion is the attraction between molecules of different substances. 2) A substance would not dissolve well in water is oil because the water molecules ar e more attracted to each other than to the monopole molecules. This shows why OLL clumps or bleeds In water and doesn’t dissolve In It. 3) The difference between acids and bases is that.
