What is the formula for density?

• density = mass x volume
• density = mass / volume
• density = mass + volume
• density = mass - volume

The positive particles of an atom are called:

• electrons 
• positrons 
• neutrons 
• protons 

Tectonic plates are:

• largest section of Earth's layers - composed of three layers
• Earth's crust and part of the upper  mantle that are broken into sections
• lowest or deepest layer of the mantle - semi rigid
• landmass in which all continents were once joined together

What determines an element's identity?

• electrons
• valence electrons
• protons
• neutrons

What determines how chemically reactive an element is?

• electrons
• valence electrons
• protons
• neutrons

Groups on the periodic table..........

• are horizontal
• are rows
• are from left to right
• go up and down

What is the formula for force?

• F=M/A
• F=A/M
• F=M*A
• F=M*F

What is the acceleration of a 50 kg object pushed with a force of 500 newtons? To solve this problem you must do - 

• 500 ÷ 50
• 50 ÷ 500
• 500 x 50

The mass of a car is 1000 kg.  How much force would be required to accelerate the car at a rate of 3 m/s²? 

• 1000 ÷ 3
• 3 ÷ 1000
• 1000 x 3

This number is  the top number in the box on the periodic table and ALWAYS equals the number of protons

• Neutrons
• Atomic Mass Number
• Group
• Atomic Number
