The facets in the same team have 2 things in common.
You are watching: Elements in the same group have similar
Common valence electrons andCommon properties
All the facets of 1st group (H, Li, Na, K, Rb, Cs, Fr) have actually one valence electron.In other words, these aspects have only one electron in your outermost orbit.
Also, the elements lying in the same group have typical properties.For example, Group 1 aspects (lithium, sodium, potassium, rubidium, cesium and francium) have similar physical properties like, metallic luster, softness, etc.Also castle have similar chemical properties. Because that example, every the alkali metals (group 1 elements) are extremely reactive come water.
These space the team 2 elements All the team 2 facets have 2 valence electrons (or 2 electron in outermost orbit).
Plus, these team 2 elements additionally show similar physical and chemical properties.Thus all the elements of group 2 have actually same variety of valence electron (i.e 2) and also they have common properties.Similarly,
All the facets of 13th team have 3 electrons in its outermost orbit.
They also show comparable properties like an excellent electrical conductivity, greater melting and boiling point, similar chemical reactivity, etc.Thus all the elements of team 13 have same variety of valence electrons (i.e 3) and also they have comparable properties.
All the elements of 14th group have 4 electrons in the outermost orbit.
They kind oxides the the type MO and also MO2 (like CO, CO2, SiO2, PbO2, etc). Hence, all the facets of group 14 have actually the same number of valence electron (i.e 4) and also they have common properties.
All the elements of 15th group have 5 electrons in that is outermost orbit.
And lock have similar chemical properties.
All the facets of 16th group have 6 electrons in that is outermost orbit.
These aspects are uncovered in their polyatomic state, they have similar outer electron construction ns2 np3, and couple of other similar properties.Thus, every the elements of team 16 have the same variety of valence electrons (i.e 6) and they show usual properties.
All the facets of 17th group have 7 electrons in the outermost orbit.
Elements of team 17 are highly electronegative and also have greater ionisation enthalpy. They react v water and type halides.Thus all the facets of team 17 have the same number of valence electrons (i.e 7) and also they show common properties.
All the aspects of 18th group have 8 electron in that outermost orbit.
All the aspects of the 18th group have completely filled valence electrons and also they space chemically inert. These elements are likewise known together Noble gases.Hence they have actually the same variety of valence electron plus they show comparable properties.(Note: 13th group elements have 3 electrons in outer shell, no 13.14th group elements have 4 electrons in outer shell, no 14.15th group facets have 5 electron in external shell, not 15.16th group elements have 6 electron in external shell, no 16.17th group aspects have 7 electrons in outer shell, not 17.18th group aspects have 8 electrons in outer shell, not 18.)
Elements the d-block and also f-block have actually some exceptions. These aspects do not display the same number of outermost electrons together that that their team number.For example, third group elements should have actually 3 valence electrons, but they have only 2 valence electrons.Similarly, fourth group elements should have actually 4 valence electrons, but they likewise have 2 valence electrons.Even some d-block aspects have 1 electron in your outermost orbit.This is due to the fact that the d-block aspects have outermost electron in s-orbitals and d-orbitals. (If you carry out not know about orbitals, visit here)Also this d-block aspects have incomplete d-orbitals. Thus electron of both s-orbitals as well as d-orbitals get involved in chemistry reaction.Similarly, f-block elements have incomplete f-orbitals.And below also, the electrons of both s-orbitals and also f-orbitals get involved in chemical reaction.Hence d-block and f-block facets have change valency or various valence electrons various other than the group number.)

Also visit: What perform periods top top the periodic table represents?
Modern periodic table covers groups and periods.The vertical columns are dubbed groups. The elements which room in the same teams have the same variety of valence electrons (i.e same number of electrons in the outermost shell).Also they possess almost similar properties.Yes there room also couple of exceptions in the facets of d-block and also f-block. But in general, because that the key group elements (s-block and also p-block), the facets of same team have the exact same valence electrons and also common properties.I expect you have clearly understood what elements in the same team have in common.If you have any doubts, feel free to asking me in the comment below.Also permit me know, has actually this write-up helped girlfriend or not?
