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.
Boron has 5 electrons and protons; the number of neutrons is specific for each isotope. Number of neutrons in a boron isotope = Mass number - 5
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.
Hydrogen- 1 electron Helium- 2 electrons Litium- 3 electrons Beryllium- 4 electrons Boron- 5 electrons Unless ionized, the atomic number of an element will say how many protons and electrons the atom will have.
Boron has three valence electrons.
three
Boron has 3 valence electrons.
Boron's atomic number is 5. Thus, its electron configuration is 1s2 2s2 2p1. If you add up the number of electrons in the "2" shell, which is boron's valence shell, you get 2 + 1 = 3 valence electrons.

theres three...
There are three valance electrons. These are the electrons in the outer shell if it is not full.
3 valence electronsThere are three valance electrons. These are the electrons in the outer shell if it is not full.
im not sure but i thinks it's three
5 electrons
there are 5 electrons in boron
