Ba - Barium


Atomic number increases from Be to Ba why?

The increase in atomic number from Be (beryllium) to Ba (barium) is due to the addition of more protons in the nucleus of the atom. Each element has a unique number of protons, and as the atomic number increases, more protons are added, leading to the formation of elements with higher atomic numbers in the periodic table.


Is Mg or Ba lighter?

Mg (Magnesium) is lighter than Ba (Barium) on the periodic table. Magnesium has an atomic number of 12 and an atomic weight of 24.305 amu, while Barium has an atomic number of 56 and an atomic weight of 137.327 amu.


Which element has 56 protons in its nucleus?

Barium. Atomic number 56 The reason for this is because Barium has 56 protons and the protons determin the atomic number (56).Also, that would be the same number of electrons. I hope this helped you :]


What atom has an atomic number of 56 and a mass number of 137 amu?

The atom with an atomic number of 56 is barium (Ba). To find the number of neutrons in this atom, subtract the atomic number from the mass number: 137 - 56 = 81 neutrons.


What element has the atomic mass of 56?

The element with an atomic number of 51 is Sb - Antimony; atomic weight = 121.75.


Which element has atomic number of 56 and mass number of 137?

The element with atomic number 56 is Barium (Ba). Given the mass number of 137, it means there are 137 total particles in the nucleus (protons and neutrons combined), so the number of neutrons for this isotope of Barium would be 137 - 56 = 81 neutrons.


What is the 56element of periodic table?

Barium, on the periodic table, has an atomic number of 56. Ba is the symbol for barium.
