The rain that occurs after a volcano erupts would most likely be acidicbasicneutral

The answer is acidic. it only becomes neutral when it falls to the soil which is alkaline. 

Rain is naturally acidic, but what makes it even more acidic are the acid gases produce by nature acid such as volcanoes (sulfur dioxide is produced by volcanic eruptions). When they erupt, the smoke that comes out of the crater is  full of acid gases.
Nitrogen oxides can also be produced naturally by lightning strikes. 

An  atom  (ours, not carroll's) consists of a positively charged  nucleus, surrounded by one or more negatively charged particles called  electrons. the positive charges equal the negative charges, so the atom has no overall charge; it is electrically neutral. most of an atom's mass is in its nucleus; the mass of an electron is only 1/1836 the mass of the lightest nucleus, that of hydrogen. although the nucleus is heavy, it is quite small compared with the overall size of an atom. the radius of a typical atom is around 0.1 to 0.25 nanometres (nm), whereas the radius of a nucleus is about 10-6  nm.  *  if an atom were enlarged to the size of the earth, its nucleus would be only 200 feet in diameter and could easily rest inside a small football stadium.read more on -
