all the elements in 3A group have three valance electrons.
Elements of group IIIA have three valence electrons: B, Al, Ga, etc. form 3+ charged ions.
The group 13 elements all have 3 valence electrons. This group has previously been known as the earth metals and the triels. The elements in this group include boron, aluminum, gallium, indium, thallium, and ununtrium.
== == It is three, the valence electrons basically depends on the last number of the group its in; such as, group 14 the valence electrons would be 4. i hope i helped
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).
The elements in 3A all have 3 valence electrons.
Halogen family members, or elements in group 17, have 7 valence electrons.
Group 7A elements have 7 electrons in their valence level, while Group 7B elements have 17 electrons in their valence level. This difference occurs because elements in Group 7A have 7 valence electrons, while elements in Group 7B have 7 valence electrons plus the 10 additional electrons in the d sublevel which contributes to a total of 17 valence electrons.
When these elements have five electrons on the outermost shell of electrons.

How many valence electrons do transition elements have?
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).
The elements in 3A all have 3 valence electrons.
Group 13 elements tend to lose three valence electrons to achieve a full outer shell configuration. They typically form 3+ ions by losing these three electrons.
Elements in the same group have the same number of valence electrons. These are the outer-shell electrons that react with other elements.
Gallium (Ga) has three valence electrons. It is in group 13 of the periodic table, which indicates that elements in this group typically have three electrons in their outermost shell. These valence electrons are involved in chemical bonding and reactions.
Boron is located in group 3A. It is group 13 in modern notation. This set of elements have three valence electrons.Boron is in the 13th group in the periodic table. Elements in this group has 3 electrons in the outermost energy level. That means they have 3 valence electrons.
Elements in the same group have the same number of valence electrons.
Halogen family members, or elements in group 17, have 7 valence electrons.
All elements in the same A group will have the same number of valence electrons.
