B) The atom's radius decreases and the atom becomes a positive ion.
C) The atom's radius increases and the atom becomes a negative ion.
D) The atom's radius increases and the atom becomes a positive ion.

Answer 1

An electron has a negative charge therefore, losing the electron will cause the atom to be a positive ion. An ion is an atom where the number of protons does not equal the number of electrons.
