# How many protons neutrons and electrons does barium 137 have?

## How many protons neutrons and electrons does barium 137 have?

When the element is barium, that means the aomic number is 56 which you see by looking for barium on a periodic table (or nowdays by entering “barium” into an online search engine). Thus the “barium” in “barium 137” means 56 protons. And the 137 for the mass number designates 137 total protons protons plus neutrons.

How many neutrons does barium Ba have?

81 neutrons
Answer and Explanation: Barium has 81 neutrons. Every atom is made of sub-atomic particles, including neutrons and protons. One atom of barium has 56 protons.

How do u find neutrons?

To find the number of neutrons, subtract the number of protons from the mass number. number of neutrons=40ā19=21.

## Where are neutron located?

the nucleus
Neutrons

Particle Symbol Location
proton p+ inside the nucleus
electron eā outside the nucleus
neutron n0 inside the nucleus

What is the location of protons?

Protons and neutrons are in the center of the atom, making up the nucleus. Electrons surround the nucleus. Protons have a positive charge.

What has a mass number of 137?

### How many protons neutrons and electrons does Ba +2 have?

Ba2+ ion has 56 protons and 54 electrons.

How many protons and neutrons does Ba Ba have?

Since barium barium ‘s atomic number is 56 56, Ba Ba has 56 56 protons. Fill in the known values where N N represents the number of neutrons. Rewrite the equation as 56+N = 137 56 + N = 137.

How many protons neutrons and electrons are in 136 barium?

Barium-136 is composed of 56 protons, 80 neutrons, and 56 electrons. Barium-137 is composed of 56 protons, 81 neutrons, and 56 electrons.

## How many protons and neutrons are in 137-56?

Thus the “barium” in “barium 137” means 56 protons. And the 137 for the mass number designates 137 total protons protons plus neutrons. To get just the number of neutrons you take the difference between protons and mass number, thus 137 ā56 = 81.

What is the mass number of a barium 137?

Explanation: When the element is barium, that means the aomic number is 56 which you see by looking for barium on a periodic table (or nowdays by entering “barium” into an online search engine). Thus the “barium” in “barium 137” means 56 protons. And the 137 for the mass number designates 137 total protons protons plus neutrons.
