Elements that have configuration of ns2np5 are members of the Halogen group(Group VIIA). They are, Fluorine, Bromine, Iodine and Astatine.
Group number 15 of Nitrogen family has ns2np3 valence shell electronic configuration.
Elements in group 14 belongs to this. They have 4 valence electrons. Carbon,silicon, are few elements in this group.
Group 2/IIA, which are the alkaline earth metals.
Group 15 also known as 5A
Antimony (Sb)
Alkaline earth metals (group 2A)
Halogens

Halogen family members, or elements in group 17, have 7 valence electrons.
The nitrogen family, group 15, is characterized by an s2p3 configuration.
8 valence electrons are there in in neon's family .They are stable in nature.
Every elements have the electrons of an atom distribution or a molecule in molecular orbitals and it is called electron configuration. The element that can be grouped in the family with above electron configuration is called antimony.
The elements in the boron family are in group 13. Therefore, their outermost shells are filled up to their s2 p1 orbitals. That means that the boron family of elements all have 3 valence electrons.
Valence shell configuration and physical and chemical properties.
Elements in the same family (or group) have the number of valence electrons in common. Ex: Family 16 - 6 valence electrons.properties
Halogen family members, or elements in group 17, have 7 valence electrons.
Elements in the same family of the periodic table have the same number of valence electrons. For light elements this amounts to the same electron configuration, but for heavier elements this is not necessarily the case, e.g. Ni: [Ar]4d8 5s2 ; Pd: [Kr] 5d10 ; Pt: [Xe] 6d9 7s1 .However the whole underlying reason for the periodic law involves the number of valence electrons, and this is expressed in the periodic table.
The family of elements that has 4 valence electrons is the carbon family, which includes carbon (C), silicon (Si), germanium (Ge), tin (Sn), and lead (Pb). These elements are located in Group 14 of the periodic table.
All of the members of the carbon family have 4 valence electrons.
The nitrogen family, group 15, is characterized by an s2p3 configuration.
8 valence electrons are there in in neon's family .They are stable in nature.

Such atoms belong to a group in the periodic table of elements.
Every elements have the electrons of an atom distribution or a molecule in molecular orbitals and it is called electron configuration. The element that can be grouped in the family with above electron configuration is called antimony.
Elements in the same family have the same number of valence electrons.
