The atomic mass of boron is approximately 10.81 atomic mass units.
Chlorine has no stable isotopes with a mass of 5. The atomic mass value listed for chlorine on the periodic table is an average of the masses of its isotopes, weighted by their natural abundance. As a result, the atomic mass of chlorine is not exactly 5 but rather around 35.5.
Basic arithmetic (5+6) suggests that the atomic mass is eleven.
Cobalt has an atomic mass of 58.933195(5) while nickel has an atomic mass of 58.6934(4). Nickel has the lower atomic mass.
It boron element. Atomic mass of it is 10.8.

The atomic mass number is calculated by adding the number of protons and neutrons in the nucleus. In this case, the isotope with atomic number 5 and 6 neutrons would have an atomic mass number of 11 (5 protons + 6 neutrons = 11 atomic mass number).
One marble typically weighs around 5 grams. The molecular mass of a water molecule is approximately 18 grams/mol. This means that 1 marble has the mass of roughly 5/18 = 0.28 moles of water molecules. To find the number of molecules, you would multiply this quantity by Avogadro's number (6.02 x 10^23), resulting in approximately 1.7 x 10^23 water molecules having the mass of 1 marble.
I think your understanding is confused. Atomic No. of '6' indicates the position in the periodic table, the number of protons, and the number of electrons. Atomic Mass is a number ( equal to or greater than atomic no.), which is the the total of protons and neutrons in the nucleus of an atom . So you atomic mass of '5' is incorrect as it is less than '6'. I think you mean 5 neutrons. If so the atomic mass is 6 + 5 = 11 This would be the isotopic element C-11 (Carbon eleven).
you can't tell the atomic mass of an atom if either the number of protons or neutrons is missing. But Boron with 5 protons and 6 neutrons has and atomic mass of 11.
