<strong>11</strong>.3 <strong>The</strong> ionic bond: transfer <strong>of</strong> electrons<br />

<strong>from</strong> one atom to another<br />

the chemistry <strong>of</strong> many elements is to attain an<br />

outer electron structure like that <strong>of</strong> noble gases<br />

ex. Na atom loses 3s electron to form Na +<br />

this process requires energy<br />

Cl atom gains an electron to form Cl -<br />

this process releases energy<br />
