1.02 Atomic Structure

Elements are made during the explosion of stars.

Elements are made of only one type of atom.

​

​Atoms
& Elements

All elements are listed on the Periodic Table of Elements.

This is the "ingredient list" for everything in the Universe.

​Ingredients for making an entire universe

Each box on the Periodic Tabel of Elements is called a tile.

This is the tile for hydrogen.

​

​And this is what a Bohr's Model of hydrogen looks like.

Hydrogen is made ONLY of hydrogen atoms

​

Elements
Elements are made of only 1 type of atom.

This is the tile for oxygen.

​

​And this is what a Bohr's Model of oxygen looks like.

​

This is the tile for carbon.

​

​And this is what a Bohr's Model of carbon looks like.

Atomic Structure

Atoms are made of protons, neutrons, and electrons.

The electrons are located outside the nucleus in the electron cloud.

​The nucleus is in the center of the atom and contains the neutrons and protons.

Protons carry a positive charge.

Neutrons carry no charge.

Electrons carry a negative charge.

Exit ticket

Draw a model of an atom on the next slide. It does not need to be perfect. I want to make sure you now know where each component is located and what their charges are in an atom.

Draw

Draw a Bohr's Model of an atom of lithium

A lithium atom contains

3 electrons

3 protons

4 neutrons

Include the charges each has and make each a different color.

​Check your work.

​3 negatively charged electrons outside the nucleus in the electron cloud.

3 positively charged protons in the nucleus at the center of the atom.

4 uncharged neutrons in the nucleus at the center of the atom.
