How many protons, neutrons and electrons are there in a neutral Cesium atom? 55 protons, 78 neutrons, 55 electrons

69 protons, 100 neutrons, 69 electrons

37 protons, 37 neutrons, 45 electrons

43 protons, 65 neutrons, 43 electrons

55 protons, 78 neutrons, 55 electrons

Explanation:

In a neutral Cesium atom we have 55 protons, 78 neutrons and 55 electrons. This can be found on the periodic table of elements.

Protons are the positively charged particles within an atom

Neutrons do not carry any charges.

Electrons are the negatively charged particles.

The amount of these subatomic particles can be obtained from the periodic table of element.

For a neutral atom, the number of protons and electrons are the same.

Since the atomic number is 55, it is also the number of protons in the atom.
