Of what group??
Practically all chemical elements can form salts.
no
The main group of elements includes all the elements in columns 1, 2, and 13 through 18 of a wide form periodic table. All the other elements are "transition elements", and those in the two horizontal rows at the bottom of a wide form periodic table are also called "inner transition" elements.
You can determine the number of covalent bonds an element can form by looking at its group number on the periodic table. Elements in group 4 can typically form 4 covalent bonds, elements in group 5 can form 3 bonds, elements in group 6 can form 2 bonds, and elements in group 7 can form 1 bond.
The majority of elements, and especially metals form salts.
Metals form salts.
Elements in group 18 do not often form bonds.
No, Group 6 and Group 7 elements can form a variety of bonds, including covalent, ionic, and metallic bonds. The tendency to form covalent bonds increases as you move across the period from Group 1 to Group 7. Group 6 elements, such as oxygen and sulfur, commonly form covalent bonds, while Group 7 elements, such as chlorine and fluorine, tend to form ionic bonds with metals.
group 17
Fluorine, chlorine, bromine, iodine, and astatine are all Group 17 elements that can combine with a metal to form a salt.
Noble gases, such as helium, neon, and argon, typically do not form bonds with other elements because they already have a stable configuration of electrons in their outermost energy level. This makes them very unreactive.
Astatine wouldn't form salt as readily as other elements in Group 17. Astatine is a radioactive metalloid. Other elements in Group 17 are nonmetals.
