Jun 04, 2008 · A neutral atom of chlorine has 17 protons and 17 electrons When chlorine reacts chemically, it typically gains one electron; giving it 17 protons and 18 electrons Remember: each proton has a positive charge + each electron has a negative charge - Chlorine ION with 17 protons (17 +) and 18 electrons (18-) Now has a NET charge of (1-)
Jan 30, 2012 · An atom is made up of equal no. of electrons and protons. To become a cation, an atom has to loss one or more electron. Thus the no. of protons becomes bigger in the cation hence the overall positive charge. This positive charge now attracts the negative electron cloud with greater force. This results in the reduction of the atomic size.
A positive ion (cation). An atom that has more electrons than protons is a negative ion (anion). Source (s): Chemistry A level.
