The answer to this question depends on which version of the Periodic Table you're referring to.
According to IUPAC, Group 7 would consist of manganese (Mn), technetium (Tc), rhenium (Rh), and bohrium (Bh). This group does not have many uses because other than manganese, the others are either rare or synthetic. Manganese is used as an alloying material in steel and is crucial to Vitamin B1.
If all of the transition metals are considered to be one group (or the old IUPAC/CAS method is used), then group 7 can refer to the halogens, or fluorine (F), chlorine (Cl), bromine (Br), Iodine (I), and Astatine (At). These elements are highly reactive and are famous for producing salts when combined with Group 1 or Alkali metals. These elements may not have many uses alone, but they have a crucial role in chemistry.

What are the uses of group 1 and 7 elements?
They combine to form salts.
How many valence electrons do elements group 17 have?
There are 7 valence electrons in elements of group-17. They are called halogens.
How many elements are there in group 1 on the periodic table?
There are 7 elements in group I of the PT. From Hydrogen(1) to Francium(87)
What group does group one from the periodic table likes to reacts with?
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.
Why are group 7 and group 1 elements usually found as compounds?
These elements are highly unstable because of for group1- IP is low and for group 7 electron affinity is high
What are the uses of group 1 and 7 elements?
They combine to form salts.
How many valence electrons do elements group 17 have?
There are 7 valence electrons in elements of group-17. They are called halogens.
Why group 7 element by their self do not have many uses?
This situation is normal. The number of chemical elements is smaller compared to the number of chemical compounds.
How many elements make up group 7 group 14 and group 18?
There is a total of 17 elements in those groups.
How many elements are there in group 1 on the periodic table?
There are 7 elements in group I of the PT. From Hydrogen(1) to Francium(87)
What is the name given to the elements in group 7?
The name given to group 7 elements in the Periodic Table are halogens.
The Halogen family elements have how many valence electrons?
Halogen family members, or elements in group 17, have 7 valence electrons.
Why are group1 and 7 found as compounds?
Group 1 elements have very low electronegativies and group 7 elements have very high electronegativities, so that both are reactive with almost every other element, the group 1 elements by donating electrons and the group 7 elements by accepting electrons.
What do all elements in group 7 have in common?
All elements in group 7 have the same no. of electrons in their outermost shells... and this no. correspondes to the group no.
What is the collective name given to the elements in group vii?
Group 7 elements are known as "halogens".
What group does group one from the periodic table likes to reacts with?
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.
Which group of elements has the highest electron affinity?
Groups 6 and 7.
