Atomic Structure/Periodic Table
Where are electrons located on an atom?
Electron shell
Which of Newton's Laws explains that objects resist a change in motion?
1st Law (Law of Inertia)
Where is the majority of the mass found in an atom?
In the nucleus (protons + neutrons)
What type of mixture do you get when you mix oil and water?
Heterogeneous mixture
What is Newtons 2nd Law?
There is a relationship between Force, mass and acceleration ~ F=ma
List the 2 parts of a longitudinal wave
Compression & rarefaction
What is the path called that electrons can flow through?
A circuit
How do you find the amount of neutrons in an atom by looking at the periodic table?
Subtract the atomic number from the atomic mass
Dissolving sugar & coffee crystals into hot water produces sweetened coffee. Identify the solute, solution & solvent.
Solute: sugar & coffee crystals
Solvent: hot water
Solution: sweetened coffee
If push on a wall with 150 Newtons of force, with what amount of force does the wall push back?
150 Newtons of force
What is the bending of a wave around a barrier or through an opening called?
Diffraction
What happens when a magnet is moved back and forth inside a solenoid?
An electric current is formed
Which two highly reactive groups on the Periodic Table bond really well together because they complete each other's outermost electron shells?
Alkali metals & Halogens
Cotton candy dissolves quickly when it combines with the moisture in your mouth. What word describes how well cotton candy dissolves?
Soluble (highly soluble)
True or False: Whether you speed up or slow down, you are accelerating.
True
Why does light bend when it enters a prism?
Light waves slow down in denser objects (air to solid)
What creates electricity from mechanical motion?
A generator
What's the difference between isotopes and ions?
Isotopes: atom with different number of neutrons
Ions: charged atoms (due to loss/gain of electrons)
What would you call a mixture of uniform composition?
Homogeneous Mixture
What Law would apply to this scenario: When you punch a punching bag you usually might feel pain or tension go through your hand after the punch.
Newton's 3rd Law
What is the apparent change in frequency of a sound caused by the movement of the listener or the source of the sound?
The Doppler Effect
What happens when you decrease the number of coils of the solenoid of an electromagnet?
The temporary magnet & its magnetic field get weaker.
