Yes they do. Groups/Families tell the number of valence electrons (the number of electrons in the outermost energy level).
Typically elements in the same group (the columns on the Periodic Table) will have the same number of valence electrons (electrons in the outermost shell).
Each column of elements share the same number of valance electrons just in different orbitals.
Because they have the same number of valence electrons and need the same number of electrons to fill their valence shells
Such atoms belong to a group in the periodic table of elements.
Elements in the same group have the same number of valence electrons.
All elements in the same group have the same number of valence electrons.
Elements in the same family have the same number of valence electrons.
Elements in the same family (or group) have the number of valence electrons in common. Ex: Family 16 - 6 valence electrons.properties
Because they have the same number of valence electrons and need the same number of electrons to fill their valence shells
Such atoms belong to a group in the periodic table of elements.
the same number of valence electrons (which is the same number of electrons in the atom's outermost shell)
Elements in the same group have the same number of valence electrons.
Group 2 metals have 2 valence electrons. In fact, the number of valence electrons of elements can be deduced from the group number (e.g. group VII elements have 7 valence electrons).
All elements in the same group have the same number of valence electrons.
Elements in the same family have the same number of valence electrons.
Elements in the same group have the same number of valence electrons. These are the outer-shell electrons that react with other elements.
similar chemical properties and characteristics
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 valence electrons for elements in the same group stay the same, since the number of valence electrons corresponds to the group number.
