What are the characteristics of the elements in the group a of the periodic table?

Answer 1

chalcogens

Answer 2

Groups 13-16 don't have just one type of element in the group: some are metals, some are metalloids, and some are non-metals. Elements in these groups have less similarities with others in the groups as in others. These elements are less reactive than those in groups 1-12, because they have a greater number of valence electrons. Group 13 is the Boron Group; Group 14, the Carbon Group; Group 15, the Nitrogen Group; Group 16, the Oxygen Group.

Answer 3

Group A elements (also known as the representative elements) have a wide range of physical and chemical properties, from highly reactive metals on the left to very reactive nonmetals on the right. They tend to form ionic compounds with elements in Group B and share common oxidation states and valence electron configurations within the group. Group A elements are often involved in forming compounds that exhibit a wide variety of colors and are essential for many biological processes.

Answer 4

Six levels or shells of electrons? By characteristics, you mean definition?

Answer 5

Helium, neon, argon, krypton, radon, and technically ununoctium.

Answer 6

There are eight "A" groups on the Periodic Table. Each individual group has its own set of characteristics.

Answer 7

They are chalcogens and oxygens.

Answer 8

chalcogens
