Elements that have configuration of ns2np5 are members of the Halogen group(Group VIIA). They are, Fluorine, Bromine, Iodine and Astatine.
Elements in the same group or family of the periodic table have the same number of valence electrons, which gives them similar chemical properties. This similarity in valence electron configuration allows them to react in similar ways with other elements.
Halogen family members, or elements in group 17, have 7 valence electrons.
8 valence electrons are there in in neon's family .They are stable in nature.
Because groups/families determine how many valence electrons the element will have. Therefore, all the elements in a group/family have the same number of valence electrons Chemimal and Physical.
The nitrogen family, group 15, is characterized by an s2p3 configuration.
Valence shell configuration and physical and chemical properties.
Elements in the same group or family of the periodic table have the same number of valence electrons, which gives them similar chemical properties. This similarity in valence electron configuration allows them to react in similar ways with other elements.
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.
8 valence electrons are there in in neon's family .They are stable in nature.
The nitrogen family, group 15, is characterized by an s2p3 configuration.
Because groups/families determine how many valence electrons the element will have. Therefore, all the elements in a group/family have the same number of valence electrons Chemimal and Physical.
Valency
Such atoms belong to a group in the periodic table of elements.
All of the members of the carbon family have 4 valence electrons.
