Name the first 10 elements of the periodic table in order.
Hydrogen, Helium, Lithium, Beryllium, Boron, Carbon, Nitrogen, Oxygen, Fluorine, Neon
What does the Roman numeral on the periodic table represent?
The amount of valence electrons in an element
What are valence electrons?
An electron in the outermost electron shell of an atom that can be lost or shared with another atom to create a molecule.
Which family is skipped in the valence electron count?
Transition Metals
What are the differences between valence electrons and regular electrons?
- Location of the electron
- The ability to be shared or lost
- An element will almost always have a different amount of valence electrons compared to total electrons
What is a Lewis Dot Diagram?
A diagram showing only element symbol and the amount of valence electrons
What is a Bohr Model?
Used to predict REACTIVITY in elements
⇒Reactivity: how likely it is for an element to form a compound with another element
☑︎Look at valence electrons (electrons in last energy level) to determine reactivity
Rules of Bohr Model
☑︎Level 1 can hold a MAX of 2 electrons ☑︎Level 2 can hold a MAX of 8 electrons ☑︎Level 3 can hold a MAX of 18 electrons ☑︎Level 4 can hold a MAX of 32 electrons *You must fill one level before going onto the next
Steps to a Bohr Model
- Draw the nucleus
- Write number of protons and neutrons in nucleus
- Draw the first energy level
- Draw electrons in energy levels in pairs
- Keep track of how many electrons are put in each energy level
Ex. Draw a Bohr Model for carbon
Protons: 6 Neutrons: 6 Electrons: 6
