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
Which group includes the halogens and which elements are in that group?
the group 7 includes the halogens and the elements are flourine, clourine,bromine,iodine and astatine
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 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.
How many elements on the periodic table of elements?
In the Periodic table of Elements There are 118 Elements 96 are metals The rest are non-metals Group 7= Halogens Group 8/0= Noble gases Going down group 1 and 2, elements become more reactive
How many valance electrons does halogen have?
Halogens are group 17 elements. They have 7 valence electrons.
