2 valence electrons are in an aluminum atom in the ground state.
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.
all the elements in group A has the same number of valence electrons
elements in same group have the same number of valence electrons
2 valence electrons are in an aluminum atom in the ground state.
Aluminum has 3 valence electrons
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.
3
Elements in the same group have the same number of valence electrons. These are the outer-shell electrons that react with other elements.
The valence electrons for elements in the same group stay the same, since the number of valence electrons corresponds to the group number.
Aluminum has 3 valence electrons.
Nitrogen
All elements in the same group have the same number of valence electrons.
Alkaline earth metals are group 2 elements and have 2 valence electrons.
