In the 'older' versions of the Periodic table this group 7 was known as the halogens (F, Cl, Br, I, At )

But later one decided that this group of halogens should be numbered as 17 in stead of 7.

This was done because the so called 'transition' elements (ten elements in each of the periods 4 till 7) have been put in between the groups 2 and 'old' 3.

So the original question: "What are the group 7 elements known as?" now has the answer:

In group 7 are the elements : Mn (25), Tc (43) and Re (75) and Uns (107) nowadays.

Why do group one elements react with group 7 elements?

group 1 elements have to 'lose' one electron to fill their outermost shell of electrons group 7 elements have to 'gain' one electron to complete their outermost shell of electrons

What is the group of elements with 7 electrons?

A Group 7 element is one in the series of elements in group 7 (IUPAC style) in the periodic table, which consists of the transition metals manganese (Mn), technetium (Tc), rhenium (Re), and bohrium (Bh). All of these elements are classed in Group 7 because their valence shells hold seven electrons. Technetium has no stable isotopes. Technetium and promethium are the only two such elements before polonium, after which no known element has a stable isotope.

What elements have 7 valence elements?

all the elements in group 7, ex: chlorine, fluorine, etc.

Synthetic elements are found in what group?

These elements are in the period 7.

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 groups are found in the periodic table?

There are 18 groups in the modern periodic table. Elements in group 1 are also known as alkali metals. Elements in group 2 are also known as alkali earth metals. Elements in group 17 are also known as halogens (salt makers). Elements in group 18 are also known as noble gases.

What is the name of the family of elements in Group IA 1?

Group IA or group 1 elements are known as alkali metals.

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.
