Does group 7A of the periodic tables contain the least reactive nonmetals?
No, Group 8A (Noble Gases) are the least reactive nonmetals because they have a full outer shell of electrons and do not readily form chemical bonds. Group 7A (Halogens) are more reactive in comparison.
What group would Group 7A most likely form a covalent bond with?
Group 7A elements, also known as the halogens, are highly reactive nonmetals that usually form covalent bonds with other nonmetals or metalloids, such as carbon, nitrogen, or sulfur. They tend to share electrons to achieve a full outer electron shell.
What are the Group 1A and Group 7A elements examples of?
Sodium and Chlorine = Sodium Chloride Potassium and Iodine = Potassium Iodide
Are bromine and chlorine in group 7a of the periodic table?
Bromine and chlorine are in group VII A, which could also be designated Group 7a, of the narrow form periodic table that was commonly used before 1980. Most chemists now prefer a wide form periodic table, in which these elements are in column 17.
What is charge on the ions formed by group 7A nonmetals Explain why?
Group 7A nonmetals (halogens) gain one electron to achieve a stable electron configuration, forming ions with a charge of -1. This is because they have seven valence electrons and need one more electron to complete their outermost energy level, resulting in a stable octet configuration (like the noble gases).
What element group are extremely reactive nonmetals?
"Halogens"Group 7A on the Periodic Table.Fluorine and everything straight below it.
Does group 7A of the periodic tables contain the least reactive nonmetals?
No, Group 8A (Noble Gases) are the least reactive nonmetals because they have a full outer shell of electrons and do not readily form chemical bonds. Group 7A (Halogens) are more reactive in comparison.
Are Group 7A elements the alkaline earth metals?
No, Group 7A elements are the halogens - a highly reactive group of nonmetals. Alkaline earth metals are found in Group 2A of the periodic table and are characterized by being shiny, silvery-white metals that react readily with water.
What group would Group 7A most likely form a covalent bond with?
Group 7A elements, also known as the halogens, are highly reactive nonmetals that usually form covalent bonds with other nonmetals or metalloids, such as carbon, nitrogen, or sulfur. They tend to share electrons to achieve a full outer electron shell.
Is group 7a on the periodic table metal non metal or metalloids?
1. After the obsolete USA system group 7A contain nonmetals. 2. After the modern IUPAC rules group 7 contain metals (A and B doesn't exist now).
What are the 4 main categories of elements found on the periodic table?
- The Group 1A elements are called alkali metals. - The Group 2A elements are called alkaline earth metals. - The nonmetals of Group 7A are called halogens. - The Group 8A elements are called the Noble Gases
Why would potassium react to group 17 elements in the periodic table?
Potassium is a metal, and it would react to group 17 (7A) because those elements are nonmetals.
What are the Group 1A and Group 7A elements examples of?
Sodium and Chlorine = Sodium Chloride Potassium and Iodine = Potassium Iodide
Does group 7A of the periodic table contain the most reactive nonmetal?
Yes. Using the modern numbering system, that group is named group 17. Group 17 contains the halogens, the most reactive nonmetals.
Are bromine and chlorine in group 7a of the periodic table?
Bromine and chlorine are in group VII A, which could also be designated Group 7a, of the narrow form periodic table that was commonly used before 1980. Most chemists now prefer a wide form periodic table, in which these elements are in column 17.
What is charge on the ions formed by group 7A nonmetals Explain why?

This is because they have seven valence electrons and need one more electron to complete their outermost energy level, resulting in a stable octet configuration (like the noble gases).
What are groups 6a-8a classified as on the periodic table of elements?
Groups 6A and 7A are typically classified as the "chalcogens" and "halogens," respectively. Group 8A is known as the "noble gases."
