Boron has 3 valence electrons out of five total electrons.

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

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

3 valence electrons. As the atomic number of boron is 5, it would have 2 electrons in the first shell and 3 valence electrons in the second shell.

Boron has 3 valence electrons. it is in period number 3 so it gets 3 valence electrons, 5 protons, and 6 neutrons

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..

There are 3 valence electrons in Boron..Remember valence electrons are in the outer shell

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

A boron atom has 5 electrons and three of them are located in the valence shell.

Tin has 4 valence electrons; when you want to figure out how many valence electrons an element has look at what column its in in the periodic table. Pay attention to the most right number (in this case 4). Eg: Boron has 3 valence electrons, etc.

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

There are two non-valence electrons in a neturol boron atom. The electronic configuration of neutral boron is 1s2, 2s2 2p1. The three electrons in the 2d shell are the valence electrons; the non--valence electrons are in the 1s orbital.

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.

Boron has an oxidation number of +3. It will try to lose the three valence electrons that it has, so that it is stable. Electrons are negative, and removing them would make the oxidation number positive.

Atomic Mass Number Of Boron.The Atomic Mass Number Of Boron Is 10.81 Its Atomic number is 5. It has 5 p neutrons , 6 neutrons and 5 electrons. Its valency is 3. it has 3 valence electrons.

3 valence electronsThere are three valance electrons. These are the electrons in the outer shell if it is not full.
