Ion - answer-An atom with a positive or a negative charge. Element - answer-is a substance that is composed of a single type of atom. Atomic Mass - answer-the sum of the number of protons and the number of neutrons. Covalent bond - answer-Strong. Occurs between atoms in the same molecule, Electron pairs are shared, creating a strong bond between atoms. Ionic Bond - answer-Moderately strong. Occurs between charged atoms (ions). Electron transfer from one atom to another, resulting in a moderately strong electrostatic attraction between oppositely charged ions. Hydrogen Bond - answer-Weak. Occurs between atoms in different molecules or parts of molecules. Weak electrostatic attraction between areas of molecules with opposite partial charges. 4 properties of water - answer-1) excellent solvent and can dissolve a wide range of substances.2) it is cohesive
