Expert Solution

Atomic number = number of proton = number of electrons

So, number of proton in an atom is 56

It has 56 electrons as well.

Atomic number is 56 is for Barium

Each element has a unique atomic number, which is listed on the periodic table above the chemical symbol for the element. The atomic number is equal to the charge on the nucleus. The atomic number also equals the number of protons in the nucleus and the number of electrons in the neutral atom of the element. For example, Fluorine (F) has the atomic number 9, which means that its atoms contain 9 protons and 9 electrons. Zinc (Zn) has the...
