Which element in period 4 is classified as an active nonmetal?
Sulfur (S) is classified as an active nonmetal in period 4.
Which element in period 2 is the most reactive nonmetal?
Chlorine (halogen), because Argon is a Nobel gas
What element is a nonmetal in period 3 atomic mass 12?
No element in period 3 has an atomic mass of 12.
Which element is a nonmetal and monatomic gas in the third period?
The element you are referring to is neon (Ne). Neon is a nonmetal and a monatomic gas located in the third period of the periodic table.
Which element in period 2 of the periodic tabke is the most reatcive nonmetal?
Fluorine is the most reactive nonmetal in period 2 of the periodic table.
The first element in a period is always an active?
That is not true. The first element in a period may be active or inactive, depending on the specific electron configuration of the element. For example, the first element in period 1, hydrogen, is not considered an active element.
What element is found in group 14 period 2?
what element is found between period 2 and group 14
What element is a liquid nonmetal halogen in the fourth period?
Bromine is a liquid nonmetal halogen in the fourth period of the periodic table. It is the only halogen that exists in a liquid state at room temperature.
What period is the element iodine found in?
Iodine is found in period 5 of the periodic table. It is a nonmetal element with atomic number 53 and is located in group 17, also known as the halogens.
What is the symbol of the element in group 7 and period 5?
The element in group 7 and period 5 is iodine, represented by the symbol I on the periodic table. It is a nonmetal that is commonly used in a variety of applications, including pharmaceuticals and dyes.
What is the most chemically active non-metal in the periodic table?
The most chemically active non-metal, and the most reactive element overall, is fluorine. Fluorine has an extremely high electronegativity, meaning that it will remove an electron form almost anything. Therefore, it is amazingly reactive, and it even reacts with glass.
What is the most chemically active nonmetal?
Lead is the heaviest non-radioactive element. It was previously thought to be Bismuth, but in 2003, it was found to be weakly radioactive with a half-life of about 19 quintillion years (19 billion billion years). Because of it's ridiculously long half-life, Bismuth can be treated as if it is stable, but it will eventually decay into Thallium.
