In the fourth period of the Periodic Table of elements, the most reactive element is potassium. It is an alkali metal, and it has the atomic number of 19.
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.
Sulfur is classified as a non-metal on the periodic table. It is in group 16, period 3.
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.
The element found in the same period as sulfur and argon, and more reactive than both, is chlorine. Chlorine is a highly reactive nonmetal that belongs to the same period (or row) as sulfur and argon on the periodic table.
Sodium is indeed a period 3 element in the periodic table. It is classified as an alkali metal and is highly reactive due to its tendency to lose its outermost electron easily.
Classification of hydrogen is: group 1, period 1 in the periodic table of Mendeleev; hydrogen is the first element in this table.
No element in period 3 has an atomic mass of 12.
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.
Fluorine is the most reactive nonmetal in period 2 of the periodic table.
The element neon is in period 2. Classified as a non-metal. :)
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 between period 2 and group 14
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.
Sulfur is classified as a non-metal on the periodic table. It is in group 16, period 3.
Chlorine (halogen), because Argon is a Nobel gas
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.
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.
