Ionic Bonds

Ionic bonds are a chemical bond resulting from the attraction between oppositley charged ions. The atoms acutually physically loose or gain electrons and for either positively or negatively charged ions. This is demonstrated below:

Where B is Boron and Cl is Clorine. The Boron atom gets rid of one of it's electrons since it had 1 electron in it's outer valence. It is now in it's most stable state with a full valence. Since Boron has lost 1 electron it becomes positively charged because there are now more protons than electrons: hence +1 charge. Clorine accepted the lone electron to fill it's outter valence and now it has satisfied it's valence and it is now full. Clorine now has 1 more electron than it has protons. This is why it now has a -1 charge. These 2 atoms now are called ions because of their charges.

1. Cations
1. are the atom that gives away their electron
2. obtains a positive charge because there are now more protons than electrons
2. Anions
1. are the atom that accepts the electron
2. obtains a negative charge because there are now more electrons than protons
