What is a Molecule?
A group of atoms bonded together
Bond: A strong force of attraction
holding atoms together in a
molecule

How is the periodic table organized?Periods: (Rows) Shows the number of energy levels
Groups: (Columns) All elements in a group have the same number of valence electrons. Elements in the same group share the same properties – do the same “things”

How do we represent atoms on paper?
How to make a Bohr model: 1. Draw a circle to represent the nucleus of the atom.

How do we represent atoms on paper?
2. Add more circles outside the nucleus to represent energy levels (electron shells).

How do we represent atoms on paper?
3. Add electrons (as small dots) to each energy level as allowed until you have the proper number of electrons for a neutral element. (# of electrons should be = to the number of protons).

Ionic Bonds• Ionic bonds form when atoms lose or gain electrons.
Sodium atom (Na) Chlorine atom (CI) Sodium ion (Na+) Chloride ion (CI-)
Na loses anelectron to CI ionic bond
gained electron
