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. 

100

This is formed when two different types of atoms chemically bond together. 

A compound (type of molecule).
100

This type of renewable resource works best in the desert where there 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. 

200

These 3 group numbers contains the most reactive elements on the periodic table. 

Groups 1,2, 17

200
Burning coal does this to the environment. 

Add air pollution.

200

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.

200

Acid rain happens when pollutants are released into this. 

The air.

200
This equation shows two different elements combining to form this. 


Mg + S = MgS

One Molecule or compound. 

300

This is the group that has the following elements in it: Mg, Ca, Ba.

Group 2 (reactive).

300

These are the risks of nuclear power.

These are the benefits of nuclear power. 

Risks: radioactive wasts, nuclear meltdown

Benefits: doesn't pollute

300

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). 

300

This group of natural resources leads to an increased amount of atmospheric carbon dioxide. 

Fossil Fuels: Coil, Oil, Natural Gas

300
Identify which of these elements is most reactive. K and Kr. 

K is in group 1 (most reactive) and Kr is in group 18 (non-reactive) so K is most reactive. 

400

The arrangement of elements in the Periodic Table is arranged by this. 

Left to right by increasing atomic number. 

400

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. 

400

This category of elements has high luster, high malleability, high ductility, and high boiling and melting points.

Metals

400

Geothermal, solar, biomass, and wind are all this type of natural resource. 

Renewable

400

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)

500
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, this is the list of disadvantages for using fossil fuels. 

1. Produce smog and air pollution.

2. Limited supply--will run out eventually. 

500

This category of elements has low luster, low malleability, low ductility, and low boiling and melting points.

Non-metals

500

This is the other name for solar panels. 

Photovoltaic Cells

500

The horizontal rolls are called this.

The vertical columns are called this.

Another name for the vertical columns is this.
