Melting points across a period
WebIn contrast, the melting points of the non-metal halides from Periods 2 and 3, such as CCl 4, PCl 3, and SCl 2, are below 0 °C, so these materials are liquids at room temperature. … WebAnd so let's move on to the concept of periods. A period is a horizontal row on the periodic table. And so, if I look at period 1, and I just move across my periodic table, hydrogen is in the first period and so is helium. I move on to the second period, so lithium, beryllium, boron, carbon, nitrogen, oxygen, fluorine, and neon.
