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.
This type of renewable resource works best in the desert where there little wind but lots of sun.
Solar panels
A compound.
These 3 group numbers contains the most reactive elements on the periodic table.
Groups 1,2, 17
Add air pollution.
Neon has an atomic number of 10. Draw what an atom of neon looks like. Identify how many neutrons and protons are in the nucleus and how many electrons are outside the nucleus.
See Mr. Lowek's Drawing.
Acid rain happens when pollutants are released into this.
The air.
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 wasts, nuclear meltdown
Benefits: doesn't pollute
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).
This group of natural resources leads to an increased amount of atmospheric carbon dioxide.
Fossil Fuels: Coil, Oil, Natural Gas
K is in group 1 (most reactive) and Kr is in group 18 (non-reactive) so K is most reactive.
The arrangement 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. This would be the most likely effect of a fossil fuel shortage.
Fossil fuel price would go up.
People would start using more renewable resources.
This category of elements has high luster, high malleability, high ductility, and high boiling and melting points.
Metals
Geothermal, solar, biomass, and wind are all this type of natural resource.
Renewable
Based on its position on the Periodic Table, this element 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)
Electron
Fossil fuels are cheap and easy to buy right now. However, this is the list of disadvantages for using fossil fuels.
1. Produce smog and air pollution.
2. Limited supply--will run out eventually.
This category of elements has low luster, low malleability, low ductility, and low boiling and melting points.
Non-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.
