Periodic Table

The number in the top left hand corner of an element box of the periodic table is known as the?

• Atomic Mass

• Electron Shell

• Atomic Elbow

• Atomic Number

How do you figure out how many electrons an element has?

• Round the atomic mass to the nearest whole number and that total is your answer.

• Find the sum of all the numbers in the upper right hand corner.

• Ask it politely

• See how many neutrons you have first

What two particles are found within the nucleus of an atom?

• Protons and Neutrons

• Neutrons and Electrons

• Electrons and Protons

The invisible tracks that go around the outside the nucleus of an atom that hold the electrons are known as?

• Train Tracks

• Electron Shells

• Neutron Nanos

• Proton Pulpits

Electrons move at what speed around the outside of an atom?

• Depends upon the gravitational pull

• Taconic Parkway speed 55 MPH

• Speed of Light (186,000 mps)

When calculating the number of neutrons and atom has, you must follow this formula?

• Round your Atomic Number to the nearest whole number and then subtract the total number of electron shells on outside of nucleus.

• Round the Electron Shells to the nearest whole number and then subtract the number of electrons.

• Round the Atomic Mass to the nearest whole number and then subtract the atomic number from that.

• Number of Neutrons = length x width x height
