A cube of a special kind of steel has sides that are all 2 cm long.
If the steel cube has a mass of 72 grams, what is the density of this kind of steel? (Show your work, and include units in your answer!)
Density = mass/Volume
Density = 72g/8cm3
Density = 9 g/cm3 [Final answer]
Two part Question:
1) I am a state of matter where particles can easily slide past each other AND I will expand to fill the volume of my container. What am I?
2) I am a state of matter where particles can easily slide past each other, I do not change in volume, but I do take the shape of my container. What am I?
1) Gas!
2) Liquid!
Particles of a substance in this state of matter vibrate around a fixed location.
Solids!
Look at the Periodic Table on the wall of the classroom (or your own that you colored). This Periodic Table uses colors to organize the elements into 3 groups.
What are the Blue elements, what are the Green elements, and what are the Yellow elements?
Blue = Metals
Green = Metalloids
Yellow = Non-metals
Your teacher has put a periodic table block and the Isotope Notation for a particular atom on the board. Determine all of the following:
Element name, Atomic Symbol, Atomic Mass, Mass Number, Number of Protons, Number of Neutrons, Number of Electrons.
Element name: Copper, Atomic Symbol: Cu
Atomic Mass: 63.546 amu Mass Number: 65
#Protons: 29 #Neutrons: 36 #Electrons: 29
Two isotopes are as follows: Ni-59 and Co-59. Which element has more:
a) Protons?
b) Neutrons?
c) Electrons?
Ni - 59 has more protons
Co - 59 has more Neutrons
Ni - 59 has more electrons
Matter is anything that has mass and takes up space. Make a table and sort the following items into the categories Matter vs. Not Matter:
Rock Water Helium gas
Applied Force Proton Sunlight
Matter: Rock, Water, Helium Gas, Proton
Not Matter: Applied Force, Sunlight
Why is most of the mass of an atom located in the nucleus?
Because protons and neutrons have most of an atom's mass, and they are located in the nucleus.
2-part T or F:
a) T or F: If two atoms have the same number of protons, but different number of neutrons, they are atoms of the same element.
b) T or F: If two atoms have the same Mass Number, but different Atomic number, they are atoms of the same element.
a) True! The number of protons determines what element an atom is.
b) False! Two atoms can have the same mass number, but they are only the same element if they have the same number of protons.
Find Nitrogen and Oxygen on your Periodic Table.
An atom of N - 14 and O - 15 would have the same number of _____________, but a different number of ____________________.
First blank: Neutrons
Second blank: Protons
You find a sparkling, clear stone while walking along the beach and wonder if it is valuable. The stone has the following properties:
High luster, can be carved, does not conduct electricity, Volume = 2 cm3, mass = 11g.
Using the following properties decide which it is: stone diamond - high luster, carvable, non conductive, density = 3.5 g/cm3
glass - some luster, somewhat carvable, non conductive, density = 2.5 g/cm3
cubic zirconia - high luster, carvable, non conductive, density = 5.65 g/cm3
Cubic Zirconia...Bummer!
