An atom has 11 protons and 12 neutrons Its atomic mass is?
atomic # is 11 and atomic mass is 23
What is the mass of boron-11?
Atomic mass of 5B11 isotope is 11.
How many neutron in sodium element?
Subtract the atomic # from the atomic mass. Atomic number = number of Protons. Atomic mass = total nucleons (Protons + Neutrons).Atomic # = 11 and Atomic Mass = 23. So 23-11 = 12 Neutrons.
What is the atomic mass of neon'?
The approximate mass is 11. Technically you could express this in units of daltons as 11 Da (Daltons previously called amu, Atomic Mass unit, or as 11 (the dimensionless, relative atomic mass which chemists simply call atomic weight) .
What is the approximate mass of a neon-11 atom?
The approximate mass is 11. Technically you could express this in units of daltons as 11 Da (Daltons previously called amu, atomic mass unit, or as 11 (the dimensionless, relative atomic mass which chemists simply call atomic weight) .

What is the explanation of the atomic mass of Sodium?
Sodium is a meta element. Atomic mass of it is 23. Atomic number of it is 11.
What is the atomic mass of an isotopes that has an atomic number of 5 and includes 6 neutrons?
Atomic Mass = 11 amu
Sodium atomic mass?
11

What is the atomic mass number of an isotopes that has an atomic number of 5 and includes 6 neutrons?
Atomic mass = 11 amu
What is the atomic mass of boran?
The atomic mass of boron, which is the element to which boran refers, is approximately 10.81 atomic mass units (amu).
What is the atomic number and atomic mass of Sodium?
Sodium (Na) has atomic number 11 and atomic mass of 22.99 g/mol
What has a atomic maass of 11?
The only radioactively stable atoms with an atomic mass of 11 are those of boron-11.
