Measurements, etc.
This variable is measured in kilograms and tells us how much matter is in a substance.
What is mass?
The particle that has a negative charge and determines how an element interacts with other elements.
What is an electron?
This tells us the identity of the element as well as its number of protons.
What is the atomic number?
A chemical bond formed by charged particles.
What is an ionic bond?
What is a chemical change?
When reading the volume of a liquid in a graduated cylinder, you look at the bottom of the __________.
What is the meniscus?
The center of the atom that contains protons and neutrons.
What is the nucleus?
These elements are soft, silvery, solids that react sometimes violently with water.
What are alkali metals?
A chemical bond formed by nonmetals that have VERY similar electronegativities.
What is a nonpolar covalent bond?
MgI2 + 2 KBr --> MgBr2 + 2 KI
Name the reaction type.
What is a double replacement reaction?
The density of an object with a mass of 25 g and a volume of 2.5 mL
What is 10 g/mL?
What is an isotope?
These elements are all unreactive due to a full valence electron shell.
What are noble gases?
The number of covalent bonds that carbon can make.
What is 4 bonds?
2 H2 + O2 --> 2 H2O
Name the reaction type.
What is a synthesis reaction?
The name of Ms. Stowe's dinosaur.
What is Stevie?
The element that forms a -1 ion and has no electrons in a level 3 orbital.
What is fluorine?
These elements gain electrons to form negative ions OR bond to each other covalently through sharing valence electrons.
What are nonmetals?
The chemical formula for a compound made from aluminum and oxygen.
What is Al2O3?
Balance the following chemical equation:
P4O10 + H2O → H3PO4
P4O10 + 6 H2O → 4 H3PO4
The name of the red stapler.
What is Bertha?
The property that explains why metals lose their valence electrons to become positively charged ions and nonmetals gain electrons to become negatively charged ions
What is electronegativity?
(also accept ionization energy)
The only metal that isn't a solid.
What is mercury?
What is dinitrogen tetrafluoride?
Balance the following chemical equation:
C7H6O2 + O2 → CO2 + H2O
2 C7H6O2 + 15 O2 → 14 CO2 + 6 H2O
