halogen NOTE added by Dr.J.): A halogen doesn't have a few valence electrons. They have 7 valence electrons.
There are 7 valence electrons in elements of group-17. They are called halogens.
Group one elements are the most reactive with group 7 elements as it is the easiest way for the elements to complete their outer shell as the group one element gives its extra electron to the group 7 element and then the group 7 element has a full shell too.
Group VII elements are known as halogens, while Group VIII elements are known as noble gases.
The 7th group of elements on the periodic table is known as the halogens. This group includes elements such as fluorine, chlorine, bromine, iodine, and astatine. Halogens are highly reactive nonmetals that readily form compounds.
Group 7 contains 5 elements, group 14 contains 6 elements, and group 18 contains 7 elements.

The name given to group 7 elements in the Periodic Table are halogens.

Group 7 elements are also known as the halogens. These elements include fluorine, chlorine, bromine, iodine, and astatine.
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.
Elements with 5 to 7 valence electrons are called "main group elements" or "p-block elements." These elements are found in groups 13 to 17 of the periodic table.
Group 7A elements have 7 electrons in their valence level, while Group 7B elements have 17 electrons in their valence level. This difference occurs because elements in Group 7A have 7 valence electrons, while elements in Group 7B have 7 valence electrons plus the 10 additional electrons in the d sublevel which contributes to a total of 17 valence electrons.

Group 7 elements are examples of transition metals (or d-block elements)
