Valence Shell<br />

Easier to Add an Electron to Valence Shell<br />

Explanation:<br />

When it comes to forming bonds between atoms in nature, they behave slightly differently than in a labratory<br />

environment where electrons are forcefully added or removed to them. Atoms whose valence shells only possess<br />

a few electrons (lower than 4), they are more likely to give them away, making them a postively charged ion ( [+] a<br />

cation ). Atoms with a valence shell with only 4 electrons are more likely to share electrons (form a covalent bond) than<br />

actually give any away. Atoms with a valence shell that contains 5 or more electrons are more likely to take electrons<br />

away from other atoms, making them a negatively charged ion ( [-] an anion ).<br />
