Period 1, which only contains two elements (hydrogen and helium), is too small to draw any conclusive trends from it, especially because the two elements behave nothing like other s-block elements. PhET sims are based on extensive education research and engage students through an intuitive, game-like environment where students learn through exploration and discovery. Students can use this physics lab report example in order to figure out the format of a physics lab report. For example the chlorine containing oxyanions can form the following acids: HClO = hypochlorous acid.
