option no A ..as an atom loses electron the positive charge increases and nucleus attracts remaining electrons more strongly...as a result radius decreases..

answer : option (A) The atom's radius decreases and the atom becomes a positive ion.
explanation : we know, protons present in nucleus of atom while electrons are revolving around the nucleus in circular orbit.
now, when an atom loses an electron, then number of proton is greater than number of electrons. due to this electrostatic force exerted by protons are greater than electrons so, nucleus attracts electrons towards itself and due to this size of atom decreases.
hence, when an atom loses an electron, the radius of atom decreases and atom becomes a positive ion.
