Berlium is a element in the Periodic Table i think. i dont know for certian what they use it for though
The element with an atomic mass of 9.012 is Beryllium, which has the atomic number 4.
Silicon has a Atomic Mass number (weight of protons and neutrons) of 28.09. Its actually 28.0855
Berilium is a non metal element. Atomic mass of it is 209.
The atomic mass is the same as the atomic weight therefore it is 9.01218. Beryllium is a non metal element. Atomic mass of it is 9.01. The atomic mass number, which is distinct from the atomic mass and the atomic weight, is 9.
9.012182 amu
Well, two times four is eight, which would be oxygen.
Beryllium has the lowest atomic mass in group 2 of the periodic table.
The Atomic Mass Of Beryllium Is 9.01218
The element symbol for beryllium is "Be" Atomic number is 4 and mass is 9.0
The Atomic Mass Of Beryllium Is 9.01218
There is no element with an atomic number of 12 and an atomic mass of 8. Atomic number corresponds to the number of protons in an atom, while atomic mass is the sum of protons and neutrons. The atomic number of an element cannot be smaller than its atomic mass.
The atomic mass of an element is the sum of the number of protons and neutrons in the nucleus. In this case, the element has 4 protons and 5 neutrons, so its atomic mass is 4 + 5 = 9 atomic mass units (amu). The number of electrons does not affect the atomic mass.
