How can you predict whether an isotope nucleus is likely to be stable

You can not predict whether an isotope nucleus is likely to be stable. There is a lack of electrons in the nucleus creating a chemical change in the atom becoming stable.

What is the half life of the Radioisotope Ag110

It is 252 days.

Is an atomic emission spectrum a continuous range of colors

No. Atomic emission spectrum is non-contiuous and it is named as line spectrum.

Why are neutrons in the nucleus of an atom if they have no charge

well they aren't going to orbit if they have no charge.

They hold the protons together. Protons, with the same charge, wouldn't stay together without neutrons.

Is Radon a radioactive substance

All isotopes of radon are radioactive.
