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.

Boron is an element. The lightest member of group 13 with 3 valence electrons


Boron group have 3 valence electrons. It is a part of group-13.


The Elements in group 13 of the periodic table (Boron, Aluminum, Gallium, etc.) have three VALENCE electrons.


Any in the group so Boron, Aluminum, Gallium, Indium, Thallium


Boron is an elemet in group 13, hence it has three valence electrons.


The expected number of valence electrons for a group 3 A element is 5 number of valence electrons.



Well, look at the group(vertical) on a periodic table and you'll find group 3A. The group number tells how many valence electrons not how many electrons in an element. So Boron(B) Aluminum(Al) Gallium(Ga) Indium(In) Thallium(Tl) will all have 3 valence electrons. The atomic # tells the total # of electrons in an element.


Simply look at the periodic table. The number of valence electrons is the same as the group number. Ex: Boron has 3, Carbon has 4, Nitrogen has 5..


Group 1 - 1 valence electron Group 2 - 2 valence electrons Group 13 - 3 valence electrons Group 14 - 4 valence electrons Group 15 - 5 valence electrons Group 16 - 6 valence electrons Group 17 - 7 valence electrons Group 18 - 8 valence electrons Groups 3 - 12 technically have 2 valence electrons, but will also use d sublevel electrons as valence electrons as well. So their number of valence electrons vary (even for the same element) and require some memorization.


The number of valence electrons found in an atom of a Group A element is equal


It is just named the boron group. The elements in the group are boron (B), aluminum (Al), gallium (Ga), indium (In), thallium (Tl), and unumtrium (Uut) (scienticially prepared). The boron group all have 3 electrons in their valence levels making them an unstable group.


The easiest way of determining the number of valence electrons is with main group elements. Main group elements are all the elements that are in groups 1,2,13,14,15,16,17,18 (not that if you were to only look at the ones digit is counts from 1 to 8) If there is an element in group 1 it has 1 valence electron If there is an element in group 2 it has 2 valence electrons If there is an element in group 13 it has 3 valence electrons If there is an element in group 14 it has 4 valence electrons See that the one's digit is equivalent to the number of valence electrons.


They are the same! Elements in group IA (alkali metals) have 1 valence electrons. Elements in group IIA (alkaline earth metals) have 2 valence electrons. Group IIIA (boron family) has 3 valence electrons, and so on.


Valence electrons are electrons that are on the outside "shell." In Group (column) 1, there is only one valence electrons for each element. In Group (column) 2, there are two valence electrons. Group 13: 3 valence electrons Group 14: 4 valence electrons Group 15: 5 valence electrons Group 16: 6 valence electrons Group 17: 7 valence electrons Group 18: 8 valence electrons There is no Group 19, so this list is done. For the metals, each element will need to be mapped out utilizing the Bohr Diagram design or something of the like as valence electrons are difficult to define due to the grouping on the periodic table. The most valence electrons that can be in an outer shell is eight. Barium (Ba) is in Group (column) 2, and thus has only two valence electrons.


The group of the element indicates the amount of valence electrons. For example, the alkali metals have one valence electron and is in group one whilst the halogens have seven valence electrons and are in group seven.


Phosphorus is a group 15 element. All group 15 elements have 5 valence electrons. Thus phosphorus has 5 valence valence electrons.


The elements in the boron family are in group 13. Therefore, their outermost shells are filled up to their s2 p1 orbitals. That means that the boron family of elements all have 3 valence electrons.


The number of valence electrons in an element is represented by the group number; for example, all elements in group one have one valence electron, all elements in group two have two valence electrons, etc.



Carbon is a group 14 element. All group 14 elements have 4 valence electrons. Thus, carbon has 4 valence electrons.


The number of valence electrons is dependent on which group of the periodic table the element is in.Since Argon is in group 8, it has a total of 8valence electrons.


Tin is a group 14 element. All group 14 elements have 4 valence electrons. Thus, tin has 4 valence electrons.


You think probable to carbon.The electron configuration of carbon is [He]2s2.2p2.


The group number corresponds with the valence electrons.
