Atoms to Ions The Atom Let’s look at Sodium Na 2 8 1 Number of Electrons 11 11+ 11- Over all charge 0 neutral Atomic Number Number of Protons The Atom Let’s look at Sodium Na 2 8 1 Number of Electrons 11 11+ 11- Over all charge 0 neutral Atomic Number Number of Protons The Atom Let’s look at Sodium Na 1 2 8 1 Oohh Sodium doesn’t like that. It wants a “happy” shell The Atom Let’s look at Sodium It could gain 7 Na Na 2 8 1 2 8 8 or drop 1 Na Na 2 8 1 2 8 Dropping 1 is easier sooooo The Atom ION Let’s look at Sodium Na Na 2 8 2 8 1 Atomic Number Number of Protons Number of Electrons Over all charge 11 11+ 11 10-neutral 10positive The Atom The ION Let’s look at Sodium Na NEUTRAL atom Na ION 1+ The Atom Let’s look at Oxygen O 2 6 Atomic Number Number of Protons Number of Electrons Over all charge 8 8+ 80 neutral The Atom Let’s look at Oxygen O 6 2 6 Oohh Oxygen doesn’t like that The Atom Let’s look at Oxygen It could gain 2 O O 2 6 2 8 or drop 6 O O 2 6 2 Gaining 2 is easier sooooo The Atom ION Let’s look at Oxygen OO 2 26 8 8 Number of Protons 8+ Number of Electrons 10 8-Over all charge 20negative neutral Atomic Number The Atom The ION Let’s look at Oxygen O NEUTRAL atom O 2- ION The ION To make life a bit easier remember these questions 1. Is it a metal or a non metal? 2. Is it a plus or a minus? 3. Valance Number ? You DO remember valance numbers?? The ION Let’s try Aluminium 1. Is itit a metal ora aminus? non metal? 2. Is a plus or 3. Valance Number ? METAL PLUS 3 Al 3+ The ION Let’s try Sulphur 1. Is itit a metal ora aminus? non metal? 2. Is a plus or 3. Valance Number ? NON-METAL MINUS 2 S 2- Lots of Happy Ions
