No. Since the atom has 31 protons, that means it's an isotope of gallium. Looking up gallium, you can determine that in nature it's composed of the two stable isotopes, gallium-69 and gallium-71, which have 38 and 40 neutrons respectively. Looking further, you will find that gallium-62 has a half life of 116.18 milliseconds which means it's quite unstable.
