What is the mass number (A) of an atom that has an atomic number (Z=26) with 29 neutrons and 26 electrons?

The mass number (A) of this atom is 55

Atom information–

Atomic number (Z) = 26Protons (p⁺) = 26Neutrons (n⁰) = 29Electrons (e⁻) = 26The atomic number (Z) of an atom is the number of protons (p⁺) it hasThe mass number (A) of an atom is characterized by the sum of the amount of protons (p⁺) with its neutrons (n⁰)

Substituting values –
