The basic unit of chemical elements
What is an atom?
Have a positive charge and have a mass of 1 AMU.
What are protons?
The amount of these that the atomic number indicates
What are protons?
A pure substance whose smallest unit is made up of TWO DIFFERENT atoms chemically bonded to one another
What is a compound?
WA Pattillo's school logo
What is a Viking?
Matter made up of only one kind of atom
What is an element?
Have no charge and have a mass of 1 AMU.
What are neutrons?
The atomic weight indicates this
What is the mass/weight of the nucleus?
A combination of two or more substances
What is a mixture?
The types of fish in Mr. Creque's fish tank
What is a guppy?
Two or more atoms bonded together
What is a molecule?
Found outside the nucleus, are negative and have no mass
What are electrons?
This is calculated by subtracting the atomic number from the atomic mass (rounded)
How many neutrons does an atom have?
A mixture that has parts that are visibly different from each other
What is a heterogeneous mixture?
A non-living pathogen
What is a virus?
Molecules make up elements (True or False)
What is false?
The center of an atom that contains protons and neutrons
What is the nucleus?
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?
A mixture that has parts that are not visibly different from each other
What is a homogeneous mixture?
The school play that is currently in production at WA Pattillo
What is Annie Jr.
An example of a molecule formula
What is O2, H20, NaCl, O3, N2, CaO, C6H12O6, etc... ?
These move at the speed of light
What are electrons?
A force that holds positively charged protons in the nucleus together (a mystery)
What is the Strong Nuclear Force
