Atoms have gained or lost electrons and are no longer electrically neutral are called _____. - ANSWERSIons Describe a single covalent bond. - ANSWERSHolds a molecule of hydrogen together, involves 2 atoms sharing 2 electrons and two chlorine atoms are held together by this bond. Describe an Ionic bond. - ANSWERSFormed by an attraction between atoms with opposite charges, bond that hold NaCl together, Involves a transfer of one or more electrons from one atom to another, Leads to the formation of a crystal lattice rather than distinct molecules and Weakest type of bond shown. Describe a double covalent bond. - ANSWERShold a molecule of oxygen together, Involves 2 atoms sharing 4 electrons, strongest type of bond shown and carbon dioxide is held together by this type of bond. T/F A water molecule is held together by 2 single polar covalent bond - ANSWERSTRUE T/F Because oxygen has a greater electronegativity than hydrogen, water molecules are polar w/ 2 partial negative charges near the oxygen atom and one partial positive charge near each hydrogen atom. - ANSWERSTRUE T/F Atoms differ in their affinity for neutrons, a property called electronegativity. - ANSWERSFALSE T/F In general, electronegativity increases from left to right across each row of the periodic table and also increases down each column. - ANSWERSFALSE T/F In a nonpolar covalent bond there is an equal sharing of electrons between two atoms while polar covalent bonds involve an unequal sharing of electrons. - ANSWERSTRUE T/F A single molecule of Oxygen is held together by 2 double non polar covalent bonds. - ANSWERSFALSE T/F A covalent bond is formed when 2 ato
