RTP stands for Room Temperature and Pressure.
One mole of any gas has a volume of 24 dm 3 or 24,000 cm 3 at rtp (room temperature and pressure). This volume is called the molar volume of a gas. This equation shows how the volume of gas in dm 3 at rtp is related to the number of moles: volume of gas at rtp = number of moles × 24.
Hope this helped!
Answer:
Option D: it's ability to lose electrons
Explanation:
Alkali metals are usually discovered in nature. They have highly reactivity at STP conditions (standard temperature and pressure conditions) and easily lose their outermost electron to form positive ions known that have a charge of +1.
Thus, what can determine the extent of reactivity of an alkali metal, is it's ability to lose electrons
A.helium<span>Hydrogen is the most abundant element in the Universe; helium is second. However, after this, the rank of abundance does not continue to correspond to the atomic number; oxygen has abundance rank 3, but atomic number 8.</span>
