Pulmonary arterial hypertension is a rare but severe disease with an estimated five-year survival rate of only 57% after diagnosis, according to the Registry to Evaluate Early And Long-term PAH disease management (REVEAL), which registers data from patients in the United States.
Concentration of elements in the ocean relative to the total concentration in the bulk silicate Earth (BSE). Of all the elements, only Cl and Br have a significant fraction in the ocean (see inset), indicating the extreme hydrophilic character for the heavier halogens.
Best Answer: Chlorine is located in Group 17 of the Periodic Table. This makes the element a halogen. All of the halogens are gases, and all gases are non-metals. You can tell if an element is a metal or a non-metal by looking at the Periodic Table. There is a stair step on the right portion of the Table. Elements touching the stair step are considered metalloids.
