In the early universe and in stars, deuterium nuclei are produced from the combination of one proton and one neutron, with the release of a gamma ray. what is the charge on a deuterium nucleus in units of qe = 1.6*10-19 c?

Explanation:

As we know that charge is always conserved

so here we have

initial total charge = final total charge

also we know that gamma rays are chargeless and massless particles

so we have

charge on deuterium is given as

Q = charge on proton + charge on neutron - charge on gamma

so we have

vapour or gas assuming atmospheriv pressure

it would be c. predictability
