Which group of the Periodic Table contains two elements that are gases at STP? Among the halogens, fluorine (F) and chlorine (Cl) are gases at STP. In the new, IUPAC approved system, the halogens are placed in group 17. In the two (ambiguous) older systeâ¦ms, their group might be labelled VIIB or VIIA. Making the world better, one answer at a time.
Answer: STP in chemistry is the abbreviation for Standard Temperature and Pressure. STP most commonly is used when performing calculations on gases, such as gas density.The standard temperature is 273 K (0Â° Celsius) and the standard pressure is 1 atm pressure.At STP, one mole of gas occupies 22.4 L of volume (molar volume).STP commonly is used when standard state conditions are applied to calculations.Standard state conditions, which include standard temperature and pressure, may be recognized in calculations by the superscript circle.t STP, one mole of gas occupies 22.4 L of volume (molar volume).
