What is the normal phase for chlorine?
The normal phase of chlorine is a gas. Chlorine comes from the greek word khloros, pale green. -34.6 C is the boiling point of chlorine. The density of chlorine is 3.214 grams per cubic centimeter. Hey pass the sodium chloride!!!
Does chlorine expire over time?
Yes, it will degrade over time. The same goes with 6% as well. Typically, the higher the initial concentration of sodium hypochlorite, the faster it will degreade. So...12% loses strength quicker than 6%, and so on. How it is stored plays a large part in this too. Higher temperatures speed the degradation process.

What is chlorine's phase at room temperature?
Chlorine is a yellow-green gas at room temperature. It is an extremely reactive element and a strong oxidising agent: among the elements, it has the highest electron affinity and the third-highest electronegativity, behind only oxygen and fluorine. Melting point of Chlorine is -101°C. Boiling point of Chlorine is -34.6°C.

The United States continued its transition from an agricultural economy to an industrial economy. In the 1920s, urban areas grew and employment opportunities were on the rise. However, the United States would soon plunge into the Great Depression.
Why is the 7th period incomplete?
7th period is considered incomplete because it consists of elements which have not been studied properly yet. Their properties may change after getting sufficient information about them.
