Presentation transcript:

Quick draw: Draw a model of an atom (Remember that an atom is made of protons neutrons and electrons) Label where you think these go in your model It’s okay if it is not perfect OR accurate… just try!

Models of atoms Structure of Life

Structure of Universe

Structure of Universe

Niels Bohr chillin’ with Einstein

Structure of Universe Protons and Neutrons are located in the center of the atom Electrons orbit around the center of the atom

Bohr Model How do we know this is what carbon looks like? 6 P 6 N

Bohr Model Protons and Electrons equal the number on top of the element in the symbol Why are there two rings? 6 P 6 N

Bohr Model Each row has a different number of rings 1 ring 2 rings

Bohr Model 6 P 6 N 1 ring 2 rings 3 rings 4 rings 5 rings

Bohr Model Why are there different numbers of electrons in different rings? 6 P 6 N

Bohr Model 1 ring with 2 electrons max in this ring 2 rings with 8 electrons max in this ring 3 rings with 18 electrons max in this ring Each ring can only hold a maximum amount of electrons as there are elements in that row

Fill in your periodic table 1 8 1 ring 2 3 4 5 6 7 2 rings 3 rings 4 rings 5 rings

Bohr Model 6 P 6 N

Bohr Model 8 P 8 N 1 ring 2 rings 3 rings 4 rings 5 rings

Bohr Model 12 P 12 N 1 ring with 2 electrons max in this ring 2 rings with 8 electrons max in this ring 3 rings with 8 electrons max in this ring

Practice Draw a Bohr model for each element:

Niels Bohr and Gilbert N. Lewis

Bohr model and Lewis Dot 6 P 6 N 1 ring 4 2 rings 3 rings 4 rings 5 rings

Bohr model and Lewis Dot 8 P 8 N 1 ring 6 2 rings 3 rings 4 rings 5 rings

Bohr model and Lewis Dot 12 P 12 N 1 ring with 2 electrons max in this ring 2 2 rings with 8 electrons max in this ring 3 rings with 8 electrons max in this ring

Lewis Dot Lewis made a simpler model for each element Lewis Dot is concerned with the valence electrons (the electrons in the outer shell) Mg has 2 valence electrons

Practice Draw a Lewis Dot model for each element:

Practice 1 8 1 ring 2 3 4 5 6 7 2 rings 3 rings 4 rings 5 rings
