Use the following word bank to help you:solvent solution solute solute solvent solution Match the Property of Water with its definition. Surface Tension Water′s tendency to form an elastic-like sheet or skin. Universal Solvent A substance (such as water) that has the ability to dissolve many other substances. Cohesion When two molecules of the same substance are attracted to one another. Adhesion When two molecules of different substances are attracted to one another. Hydrogen bonds Attraction between a partially positive hydrogen atom of a water molecule and a partially negative oxygen atom of another water molecule. Sort the cards into the category: "Cation" or "Anion." Cation a positively charged ion an atom that LOST an electron Anion a negatively charged ion an atom that GAINED an electron Sort the cards into the category: "Covalent Bond" or "Ionic Bond." Covalent Bond non-metal + non-metal electrons are SHARED between atoms H2O Ionic Bond metal + non-metal electrons are TRANSFERRED between atoms NaCl Fill in the blanks in the following sentences.Word Banks:nonpolar polar 8 valence octet A polar covalent bond is formed when electrons are not shared equally.A nonpolar covalent bond is formed when the electrons are shared equally by the two atoms.The electrons in the outermost shell (main energy level) of an atom are called valence electrons; these are the electrons involved in forming bonds.The octet rule states that toms lose, gain, or share electrons in order to acquire a full set of 8 valence electrons. Match the word with its definition. Ionization Energy The amount of energy required to remove an electron from an atom. Electrolysis A process by which an electric current breaks chemical bods. Energy Levels A region of an atom in which electrons of the same energy level are likely to be found. Atomic Number The number of protons in the nucleus of an atom of a given element. Atomic Mass The number of protons and neutrons found in a single atom of a given element. Sort the cards into the category: "Group" or "Period." Group A vertical column of elements in the periodic table. Period A horizontal row of elements in the periodic table.
