Derek and Lucas Trivia
100
The basic unit of chemical elements
What is an atom?
100
Have a positive charge and have a mass of 1 AMU.
What are protons?
100
The amount of these that the atomic number indicates
What are protons?
100
A pure substance whose smallest unit is made up of TWO DIFFERENT atoms chemically bonded to one another
What is a compound?
100
Derek's favorite food (Breakfast)
What are waffles?
200
Matter made up of only one kind of atom
What is an element?
200
Have no charge and have a mass of 1 AMU.
What are neutrons?
200
The atomic weight indicates this
What is the mass/weight of the nucleus?
200
A combination of two or more substances
What is a mixture?
200
The amount of studying/work that Lucas has done for his finals already
What is 0?
300
Two or more atoms bonded together
What is a molecule?
300
Found outside the nucleus, are negative and have no mass
What are electrons?
300
This is calculated by subtracting the atomic number from the atomic mass (rounded)
How many neutrons does an atom have?
300
A mixture that has parts that are visibly different from each other
What is a heterogeneous mixture?
300
The number of group project presentations Derek has missed in this class
What is 1?
400
Molecules make up elements (True or False)
What is false?
400
The center of an atom that contains protons and neutrons
What is the nucleus?
400
A different form of the same element that has the same number of protons but a different number of
neutrons, giving them different atomic masses,
but keeping the same chemical properties
What is an isotope?
400
A mixture that has parts that are not visibly different from each other
What is a homogeneous mixture?
400
The number of Physical Science for Teachers classes that Lucas has slept through
What is 4?
500
An example of a molecule formula
What is O2, H20, NaCl, O3, N2, CaO, C6H12O6, etc... ?
500
These move at the speed of light
What are electrons?
500
A force that holds positively charged protons in the nucleus together (a mystery)
What is the Strong Nuclear Force
500
X=element, Y and Z=compound, W=mixture
