100
This element's symbol is K.
What is potassium?
100
These are the three subatomic particles.
What are protons, neutrons, and electrons?
100
This type of ion forms when an atom loses electrons.
What is a cation?
100
This is one reason why some people choose bottled water.
What is portability, convenience, low cost, or cleanliness/purity? (or other valid response)
100
This attraction holds atoms together into compounds.
What is a chemical bond?
200
This element is in Group 1, Period 6.
What is caesium?
200
These subatomic particles are located in the nucleus.
What are protons and neutrons?
200
An atom that has gained electrons has this type of charge.
What is negative?
200
Of the two elements that make up a water molecule, this one is likely to form anions to become stable.
What is oxygen.
200
An atom is stable when it has a valence of this many electrons.
What is 8?
300
Group 8 contains these non-reactive elements.
What are the noble gases?
300
This subatomic particle determines the identity of an element.
What are protons?
300
Ions form when atoms gain or lose these to become stable.
What are electrons?
300
Most plastics are made from this component, which makes environmentalists worried.
What is crude oil?
300
This type of bond involves the sharing of electrons rather than the transfer of them.
What is a covalent bond?
400
The number of neutrons found in cobalt.
What is 32?
400
This electron shell can hold up to 8 electrons.
What is the second shell?
400
This Group on the Periodic Table frequently forms ionic bonds with the halogens.
What are the alkali metals?
400
The vast majority of water bottles end up in landfill because this action is not taken.
What is recycling?
400
This is what a Lewis Dot structure would look like for barium.
What is (draw symbol Ba and place two dots around it-- not paired up)
500
Gold-197 and Gold-195 are two examples of this concept. (Hint-- the number is the mass number)
What are isotopes?

A complete Bohr model diagram includes these things.
What are protons and neutrons in a nucleus and electrons in shells?
500
This is the ion formula for selenium.
What is Se2-?
500
This chemical leaches into water from plastic and is the greatest health concern when it comes to bottled water.
What is BPA? (You won't need to remember this for Tuesday, just for fun to see if you remembered from the water discussions)
500
This term determines the reactivity of an element. (Hint- it refers to the outer shell electrons)
What is valence?
