100
This is the NAME of the Group or Family on the Periodic table that is very reactive in water.
What is the Alkali Metals?
100
These are the 3 particles in an atom AND their charges
proton = + neutron = ( ) electron = -
100
These properties can be observed without changing the substance into something else.
What is a physical property?
100
This is the density if the mass is 750 grams and the volume is 96.2 mL. Round to one decimal place
What is 7.8 g/mL?
100
This is when two or more substances are mixed together but none of the substances chemically bonds with the other
What is a mixture?
200
This is how the periodic table is arranged.
What is Atomic Number?
200
This is what the center of the atom is called AND the particles in it.
What is the Nucleus and Protons/Neutrons?
200
These are 3 chemical properties.
Answers may vary: What is Flammability, Toxicity, Ability to rust, and Reactivity with other substances?
200
Find volume if the density is 13.6 g/mL and the mass is 3000 g. Round to one decimal place
V = 220.6 mL
200
This is the name given to anything that has both mass and volume.
What is matter?
300
This is the NAME of the family of elements that has 7 valence electrons.
What is the Halogens?
300
This is what it is called when two atoms chemically bond together
What is a compound or molecule?
300
This is a type of mixture where one substance does not fully dissolve into the other. (example = sand and water)
What is a suspension?
300
Find Mass if the density is 11.3 g/mL and the volume is 159.3 mL Round to one decimal place
What is 1800.1 g?
300
This is the name of physical property that can easily be molded and bent without breaking, like aluminum foil
What is malleability?
400
This is the NAME of the group of elements that is highly non-reactive.
What is the Noble Gases?
400
DAILY DOUBLE: Draw a Bohr Model of the following element: 17 Cl 35
See example
400
This is what we call a mixture that contains a solute and a solvent, in which the solute is completely dissolved in the solvent. (ex: Sugar in water)
What is a solution?
400
Calculate the volume of a brick with a length of 5 cm, a width of 2 cm, and a heigth of 10 cm
What is 100 cm^3?
400
This is how many valence electrons are in the element Phosphorous (P).
What is 5?
500
This large section of elements is opposite of the transition metals, for they have low luster, low melting point, are not malleable or ductile, have low density, but are necessary for life. (Not specifically discussed in class).....
What is the nonmetals?
500
This is the rule that states most elements want 8 valence electrons in their outer shell to become stable
What is the Octet Rule?
500
This is what we call a chemical reaction that RELEASES heat or energy (not fully discussed in class...)
What is an EXOTHERMIC Reaction?
500
This is what it is called when we calculate the volume of an irregular object using water.
What is water displacement?
500
This is the name (first OR last) of the Russian scientist who created the Periodic Table.
