What element is the most active nonmetal?
Chlorine. The most active nonmetal in any period is second to last (halogens), right before the noble gases.
What group of elements are the most reactive nonmetals?
halogens
Elements in group 17 are called halogens (see Figure below). They are highly reactive nonmetals with seven valence electrons. The halogens react violently with alkali metals, which have one valence electron.
What is the most active nonmetal in group 7A?

What family has the most reactive metals?
alkali metals
The most reactive metals belong to the alkali metals element group. Reactivity increases as you move down the alkali metals group.
Which region contains the most non reactive nonmetal family of elements?
Group 7A (or 17) elements are also called halogens. This group contains very reactive nonmetal elements. The noble gases are in group 8A. These elements also have similar properties to each other, the most significant property being that they are extremely unreactive, rarely forming compounds.
Which of the following groups contains the most active metals?
The family that contains the most reactive metals are the alkali metals.
What family of metals is most reactive?
Alkali metals
Alkali metals are among the most reactive metals. This is due in part to their larger atomic radii and low ionization energies. They tend to donate their electrons in reactions and have an oxidation state of +1.
What is the most active element in group 1?
francium
Reactivity of Group 1 Elements The reactivity of alkali metals increases from the top to the bottom of the group, so lithium (Li) is the least reactive alkali metal and francium (Fr) is the most reactive.
What metal family is the most reactive and why?
The reactivity of alkali metals increases from the top to the bottom of the group, so lithium (Li) is the least reactive alkali metal and francium (Fr) is the most reactive. Because alkali metals are so reactive, they are found in nature only in combination with other elements.
Which family of elements are non reactive gases and have filled energy levels?
Noble gases
Noble gases are nonreactive, nonmetallic elements in group 18 of the periodic table. Noble gases are the least reactive of all elements. That’s because they have eight valence electrons, which fill their outer energy level.
What are the most active nonmetals?
The most active nonmetals belong to the halogen family, which sits to the left of the noble gases on the right side of the periodic table. The halogens are so reactive that they are never found in nature by themselves. The elements fluorine, chlorine, bromine, iodine and astatine make up the halogen family.
Where are nonmetals found on the periodic table?
The most active nonmetals belong to the halogen family, which sits to the left of the noble gases on the right side of the periodic table. The halogens are so reactive that they are never found in nature by themselves.
Which of the following elements is not a metal?
So, if we include the nonmetals group, halogens, and noble gases, all of the elements that are nonmetals are: Hydrogen (sometimes) Carbon. Nitrogen. Oxygen. Phosphorus. Sulfur. Selenium.
Do nonmetals form more compounds than metals?
Even oxygen has a metallic form as a solid. Even though there are only 7 elements within the nonmetals group, two of these elements (hydrogen and helium) make up about 98% of the mass of the universe. 1 Nonmetals form more compounds than metals. Living organisms consist mainly of nonmetals.
