Group 3 is part of the transition metal series. This means that the number of outer shell electrons the element has will depend on its oxidation state.
Group 13 or 3A has 3 outer shell electrons, 2s electrons, and 1 p electron.
3 electrons in their outermost shell.

The elements belonging to Group IA and IIA.
halogens are the element placed in the 17th group of the period table. they have valency 1 and are the most reactive and the most electronegative elements.Halogens include flourine,chlorine,bromine,iodine and astatine (the radioactive element) their electronegativity decreases down the group. halogens are also called as salt forming elements.

All elements in group 7 have the same no. of electrons in their outermost shells... and this no. correspondes to the group no.
the elements belonging to group 1 and 2 of the periodic table are s-block elements. it includes elements in which the outermost subshell is s and that have 1 or 2 electrons in their outermost shell.

They don't. Of the main group, or representative elements, group 1 elements are the only ones whose atoms have only 1 electron in their outermost energy levels.
Group 1 elements are metallic in nature. They have 1 electron in their outermost octet.
The number of electrons in the outermost orbital.
In the periodic table, group indicates the number of valence electrons in the outermost shell. E.g. Group I- the elements in that group have one valence electron in the outermost shell.
name the group of elements that have only one electron in their outermost energy level

That's group 13, otherwise known as group 3A. It includes the very common element aluminum, along with the somewhat less common elements boron, gallium, indium, and thallium. These elements all have 3 electrons in their outer, or valence shell. Two of those electrons are in the s suborbital, and one is in the p suborbital.
All elements in group 7 have the same no. of electrons in their outermost shells... and this no. correspondes to the group no.
