Q1: The removal of a non-neutral subatomic particle converts the atom into a:

ANS:A - charged ion

Non neutral subatomics are protons and electrons. If an electron removed from an atom it undergone positive charge, when an electron added to atom then it get negative charge. Either it is positive or negative totally it is a charged ion. If we add or remove protons from an atom. That atom changes completely to next element in periodic table. Example : If hydrogen gets a proton in addition then it changes to helium of positively charged. Why because this new helium atom consists of just one electron. But as per given options. Only first one follows this.
