Yes; it contains 2 protons and 2 neutrons.
Yes, it is true.
Mass of hydrogen atom = 1 amu Mass of ununoctium atom = 294 amu So ratio = 1 : 294
4.0026 amu
The atomic mass of Hydrogen is 1.00794 amu.
The weight (mass) of an atom with 9 protons will vary depending on the number of neutrons. 9 protons defines the atom as fluorine (F), and it can have 10 protons, making the mass 19 amu, or it can have a mass of 14 amu up to 31 amu, but the only stable isotope is the one with a weight (atomic mass) of 19 amu.
16 amu
Mass of hydrogen atom = 1 amu Mass of ununoctium atom = 294 amu So ratio = 1 : 294
It will be 131.29 amu

An Aluminum atom is 26.9815 AMU on *average*.
Devide mass by atomic mass to get 15 atoms Ne 300 (amu) / 20.2 (amu/atom Ne) = (14.9 atoms) = 15 atoms (= 303 amu)

Mass of C-12 atom = 12 amu mass of C-12 atom = am So atomic mass of A = 4 amu source ; www.examville.com
The atomic mass unit (amu) is defined as 1/12 the mass of a carbon-12 atom. It is a unit of mass that is used to describe the masses of atoms and molecules. The mass of a proton is actually slightly less than the mass of a carbon-12 atom, so it is not equal to 1 amu. However, the mass of a protium atom (which is an atom that consists of a single proton and no neutrons) is very close to 1 amu. This is because the mass of the proton makes up most of the mass of a protium atom. Therefore, protium is often said to be "approximately equal" to 1 amu.
