The group 18 elements are the noble gases, which are extremely inert. Some of them, heavier than argon, do form highly reactive compounds principally with fluorine.
Elements in Group 16, also known as the chalcogens, typically seek to bond with elements in Group 1 (alkali metals) and Group 2 (alkaline earth metals). This is because Group 16 elements have six valence electrons and require two additional electrons to achieve a stable octet configuration. Group 1 elements, which have one valence electron, can readily lose that electron to bond with Group 16 elements, while Group 2 elements can lose two valence electrons. This results in the formation of stable ionic compounds, such as oxides and sulfides.
Elements from the group 2 of the periodic table form cations.
Group 1 elements can form 1 bond, Group 14 can form 4 bonds, Group 16 can form 2 bonds, and Group 17 can form 1 bond.
There's not really a "group of double bonds." There are five elements that'll do it - carbon, nitrogen, oxygen, phosphorus and sulfur.
If you meant to say "elements ARE most likely to bond with," which is probably what you meant, then the answer would be 7A(or 17), also called the Halogens. "Halogen" actually means "salt-forming." When you take a chlorine (7A) and sodium (1A), you end up with table salt! ---- In a nutshell, the answer is Group 7A, or 17.
Elements in group 18 do not often form bonds.
Elements in Group 16, also known as the chalcogens, typically seek to bond with elements in Group 1 (alkali metals) and Group 2 (alkaline earth metals). This is because Group 16 elements have six valence electrons and require two additional electrons to achieve a stable octet configuration. Group 1 elements, which have one valence electron, can readily lose that electron to bond with Group 16 elements, while Group 2 elements can lose two valence electrons. This results in the formation of stable ionic compounds, such as oxides and sulfides.
Elements from Group 1 (such as sodium) and Group 2 (such as magnesium) would bond ionically with chlorine. Sodium would form NaCl (sodium chloride) and magnesium would form MgCl2 (magnesium chloride) through ionic bonds with chlorine.
In general, when an element in group 1 or group 2 combines with elements in group 16 or group 17, ionic bonds are formed between the two elements.
Elements from the group 2 of the periodic table form cations.
A metallic bond is a bond between two metals from the same group.
Group 16 or the chalcogens.
Group 15 elements will typically bond as an anion to a cation from groups 1,2, or 13. They can also bond covalently to any of the elements from groups 13-17.
Elements with high electronegativities are typically found in Group 17, the halogens, and in Group 16, the chalcogens, of the periodic table. These elements have a tendency to attract electrons towards themselves in a chemical bond.
Group 1 elements can form 1 bond, Group 14 can form 4 bonds, Group 16 can form 2 bonds, and Group 17 can form 1 bond.
There's not really a "group of double bonds." There are five elements that'll do it - carbon, nitrogen, oxygen, phosphorus and sulfur.
Bromine, being in group 17 of the periodic table (halogens), is more likely to bond with elements in group 1 (alkali metals) or group 2 (alkaline earth metals) to form ionic compounds.
