Bonding
What kind of bond forms between two hydrogen atoms?
What is: a covalent bond
How many valence electrons in hydrogen?
What happens when you split the nucleus?
What is: bomb/release of energy, etc...
Where does most of our oxygen come from?
What is: the ocean
Where did P. Siemes see the bomb drop? What was the name of the city?
What is: Nagasaki
Who discovered/declared bonding?
Who is: Lewis
How many valence electrons in oxygen?
What is: six.
What happens when you add or subtract electrons?
What are: ions
What do we release when we exhale?
what is: CO2
What kind of bomb dropped in front of Siemes? What element was used...
What is: uranium
Why are the bonds in H2O NOT just covalent bonds?Why are they polar covalent?
What is: because oxygen is more electronegative/oxygen and hydrogen are different atoms

Show how SO2 would form from S and O2. Show ions if it is ionic.
Teacher will judge:
S has 6, O has six, Sulfur forms two double bonds with each oxygen atom
How many more valence electrons would beryllium need to have a full valence shell?
What is:six
When you mess with the number of neutrons, what happens to the charge of the atom?
what is: nothing
