Boron.
Boron is a non metal element. Atomic number of it is 5.
Boron is a non metal element. Atomic number of it is 35.
We can find Polonium as a non metal element. Atomic number of it is 84.
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 is a none metal element. atomic number of it is 5.
Boron is a non meta element. Atomic number of it is 5.
Boron is a non meta element. Atomic number of it is 5.
The atomic mass of Boron (B) is 11 but to be more accurate, the atomic mass is 10.81.
The atomic weight of an element with an atomic number of 9, which corresponds to fluorine, is approximately 19. It is calculated by adding the number of protons and neutrons in the nucleus of the atom.
Bromine, because Bromine has an atomic mass of only 5.
neutrons in berylium are 5 because Atomic mass - 9 Atomic number - 4 number of neutrons = Atomic mass - Atomic number = 9 - 4 = 5 neutrons = = berylium is metal = no berylium is not a true metal most of its properties are similar to the non metals.....
Dubnium atomic number 105
