Answer to Question 1
A positive ion has lost one or more electrons, leaving the positively charged protons in the nucleus without a balancing negative charge on the particle, resulting in a positively charged ion. A negative ion has gained one or more electrons, adding more negative charge to the orbital shells, resulting in a negatively charged ion.
