Which is most likely to be part of an ionic bond?

a. an atom with no valence electrons
b. an atom with one valence electron
c. an atom with two valence electrons
d. an atom with three valence electrons

I think the correct answer from the choices listed above is option A. An atom with no valence electrons is most likely to part of of an ionic bond. This is because valence electrons are the particles that bonds to other atoms and in an ionic bond there is a complete transfer of electrons.

10.063g / 10.00 ml = 1.0063 g/ml which rounds off to 4 sig figs as: 1.006 g/ml

They are all decomposition reactions.
