Elements
Which Element is represented by the symbol O
Oxygen
Define acceleration.
Acceleration is the increase in the rate or speed of something.
This formula represents which chemical reaction?
A+B ------> AB
Synthesis Reaction
How many atoms are on the first energy level of a Bohr Model?
2
A Rock sitting on top of a hill. Is this a display of potential of kinetic energy
Potential energy
What does the atomic number tell you about an element?
The atomic number allows me to know how many protons and electrons are in an element.
Solve for acceleration. A= Vf - VI / Time
The motorcycle goes from 0 to 70 m/hr. It took the motorcycle 5 seconds to reach this velocity. What was the acceleration of the motorcycle?
14 m/h.s

Double Reaction
How many Valance electrons does the element Aluminum have?
3
Define Kinetic energy.
Kinetic energy is moving energy
Who Created the Periodic Table?
Dmitri Mendeleev
Solve for acceleration. A= Vf - VI / Time
You can speed up from 0 to 25 feet/s in 25 seconds and your brother can speed up from 0 to 6 feet/s in 6 seconds.
neither you nor your brother is faster.
Identify the chemical reaction.
2H2O ------> 2H2 + O
Decomposition Reaction
On the board Construct a Bohr model for the element Nitrogen
Nitrogen has an atomic number of 7
the first energy level has 2 atoms
Second energy level 5 atoms
What's the difference between potential and Kinetic energy?
The difference between potential and Kinetic Energy is that energy associated with the motion of an object is called kinetic energy. Energy stored in an object due to its position is called potential energy.
