How many protons would be present in an atom of barium?

Answer 1

There are four protons. Also four neutrons and four electrons

Answer 2

There are 56 protons in every barium atom. You'll recall that the number of protons in an atom is the sole determinate of its elemental identity. But the number of neutrons varies depending on which isotope of the element we are considering. Barium has seven stable isotopes, and they have 74, 76, 78, 79, 80, 81 and 82 neutrons in them. There are a number of unstable isotopes of barium, and their neutron count ranges from 58 through 97, less the seven stable isotopes noted. Use the link below for more information.

Answer 3

All atoms of the same element will have the same number of protons, so you won't need to worry about exceptions. To figure out how many protons an atom has, you simply have to look at a periodic table. The number of protons is the same as the atomic number, which is 56 in this case.

Answer 4

An atom's weight is determined by the number of protons it contains, and the atomic weight of Barium is 56. Therefore, there are 56 protons in Barium.

Answer 5

Barium has 56 protons.

Answer 6

Barium has an atomic number of 56.

Answer 7

56 for each atom of barium in the sample
