Which characteristics tend to decrease when the elements in Period 3 on the Periodic Table are considered in order from left to right?
What is metallic character and atomic radius
200

The combining of two small nuclei into one larger one, usually producing a lot of energy (such as on the surface of the sun)

what is fusion?

200
What is the total number of electron pairs shared between the carbon atom and one of the oxygen atoms in a carbon dioxide molecule?
What is 2
200
Heat is added to a 200.-gram sample of H2O(s) to melt the sample at 0°C. Then the resulting H2O(ℓ) is heated to a final temperature of 65°C. Show a numerical setup for calculating the total amount of heat required to raise the temperature of the H2O(ℓ) from 0°C to its final temperature.
What is q=mCT, or 54,340 J
300
An atom in an excited state has an electron configuration of 2-7-2. Write the electron configuration of this atom in the ground state.
What is 2-8-1
300
An atom of which element has the greatest attraction for electrons in a chemical bond?
What is Fluorine because it has the highest electronegativity
300

medical applications such as treating cancer and thyroid disorders, carbon dating, geological dating

What are some applications of isotopes? 

300

What is the lewis dot diagram for a non polar molecule with polar bonds 

What is CO2?

300
Compare the amount of heat required to vaporize a 200.-gram sample of H2O(ℓ) at its boiling point to the amount of heat required to melt a 200.-gram sample of H2O(s) at its melting point.
The heat of vaporization is higher, so it takes more heat to vaporize than it does to melt.
400
The gold foil experiment led to the conclusion that each atom in the foil was composed mostly of empty space because most alpha particles directed at the foil
What is went directly through the foil
400

Heat is added to a 200.-gram sample of H2O(s) to melt the sample at 0°C. Then the resulting H2O(ℓ) is heated to a final temperature of 65°C. Determine the total amount of heat required to completely melt the sample.

What is q=mHf, so 66,800J

500
The light emitted from a flame is produced when electrons in an excited state
What is fall back to the ground state and release energy
500
Two sources of copper are cuprite, which has the IUPAC name copper(I) oxide, and malachite, which has the formula Cu2CO3(OH)2. Copper is used in home wiring and electric motors because it has good electrical conductivity. Determine the oxidation number of oxygen in the carbonate ion found in malachite.
