Atomic Bonding

._._. Chemical Bonds: A mutual attraction between the nuclei and valence electrons of different atoms that bind the atoms together. _._.


✺ Atoms ⓛⓞⓥⓔ to bond! Individual atoms have high potential energy, which is lowered by bonding. Nature favors low potential energy, because it's more STABLE.



✺The Octet Rule✺

✺ Atoms are most stable with eight valence electrons in their outermost shell.

✺ Boron is an exception to this rule because it is stable with only six valence electrons.

✺ All elements in the fourth period are exceptions as well, because they are stable with more than eight valence electrons.

Ways To Determine Bond Type

✺Appearance

✺Solubility

✺Melting point

Ionic Bonds

✺soluble

✺high melting point

✺conducts as liquid and when dissolved

Ionic Character

Covalent Bonds

✺mostly soluble

✺low melting pint

✺never conducts

✺Conductivity

Metallic Bonds

✺shiny

✺not soluble

✺high melting point

✺conducts

✺Elements want to reach noble gas configuration.

✺Stability is the goal for all elements.

Please ignore the mistake with the conductivity bullet point.
