Outer or valence electrons
All elements in the groups (excluding transition metals) have the same number of electrons as the group number.
All 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.
All elements in a group have same chemical properties. They have same number of valence electrons.
All elements in the same A group will have the same number of valence electrons.
All elements in the same group have the same number of valence electrons.
The valence electrons for elements in the same group stay the same, since the number of valence electrons corresponds to the group number.
All elements in the same A group will have the same number of valence electrons.
All elements in the same group have the same number of valence electrons.
all the elements in group A has the same number of valence electrons
elements in a group have the same number of valence electrons
The electron configurations of the elements in each main group are regular and consistent:the elements in each group have the same number of valence electrons.
