Periodic Table
There are this many elements on the periodic table (in 2024).
118
The problem with power plants releasing thermal energy into a river is that it does this.
Hurts/kills/threatens existence of aquatic (in water) organisms.
This is formed when two different types of atoms chemically bond together.
A compound (type of molecule).
This type of renewable resource works best in the desert where there is little wind but lots of sun.
Solar panels
Sodium Chloride (NaCl) is formed in a chemical reaction between sodium (Na) and Chlorine (Cl2). From this information, we know that sodium chloride is this.
A compound.
These 3 group numbers on the periodic table contain the most reactive elements on the periodic table.
Groups 1,2, 17
Burning coal does these two things to the environment.
Adds air pollution + causes acid rain
Burning coal does these two things to the environment.
Acid Rain and causes global warming.
Acid rain happens when pollutants are released into this.
The air.
This equation shows two different elements combining to form this.
Mg + S = MgS
One Molecule or compound.
This is the group that has the following elements in it: Mg, Ca, Ba.
Group 2 (reactive).
These are the risks of nuclear power.
These are the benefits of nuclear power.
Risks: radioactive wastes, nuclear meltdown
Benefits: doesn't pollute
These are the risks of nuclear power.
These are the benefits of nuclear power.
Radioactive waste and possible nuclear meltdown.
Doesn't pollute.
This group of natural resources leads to an increased amount of atmospheric carbon dioxide.
Fossil Fuels: Coil, Oil, Natural Gas
Identify which of these elements is most reactive. K or Kr? Be ready to explain how you know.
K is in group 1 (most reactive) and Kr is in group 18 (non-reactive) so K is most reactive.
The organization of elements in the Periodic Table is arranged by this.
Left to right by increasing atomic number.
Mr. Tell read that the amount of fossil fuels available is declining (going down) which is leading to less supply for cars. Describe what would happen as a result.
Fossil fuel price would go up.
People would start using more renewable resources.
This is the reason that Gold (Au) is below Copper (Au) on the periodic table.
Gold (Au) has a greater atomic number and a greater atomic mass than Copper (Cu).
Geothermal, solar, biomass, and wind are all this type of natural resource.
Renewable
Based on its position on the Periodic Table,which of these elements is a nonmetal: K, V, Si, or F.
K Group 1 (metal)
V Group 5 (metal)
Si Group 14 (metalloid)
F Group 17 (non-metal)
This subparticle of the atom has no weight which is why it isn't included in the atomic mass.
Electron
Fossil fuels are cheap and easy to buy right now. However, these are the disadvantages for using fossil fuels.
1. Produce smog and air pollution.
2. Limited supply--will run out eventually.
This category of elements has high luster, high malleability, high ductility, and high boiling and melting points.
Metals
This is the other name for solar panels.
Photovoltaic Cells
The horizontal rolls are called this.
The vertical columns are called this.
Another name for the vertical columns is this.
