Most reactive metal and non-metal?
What is Francium and Fluorine
100
Charge by induction - what is it and how does it happen?
What is movement of electrons within a substance, caused by a nearby charged object, without direct contact between the two objects E.g. Holding a negatively charged balloon near a wall - repels electrons in wall, causes positive charge on surface of wall
100
Difference between food chain and food web?
What is food chains show the flow of energy in one direct pathway, while food webs are many food chains combined
100
What is fifth planet from Sun?
What is Jupiter.
100
Which WHMIS symbol indicates prolonged toxic effects (E.g. causes cancer)?
What is Capital T with dot at the bottom
200
Then electron configuration of a sodium ion would be the same as which Noble gas?
What is Neon.
200
Does the hold on electrons get stronger as you go down the electrostatic series, or up?
What is down
200
How does the amount of biodiversity in a forest compare to a golf course?
What is less biodiversity in a golf course
200
What term describes a collection of stars in a pattern?
What is constellation
200
Covalent vs. ionic bond?
What is covalent bonds are between two non-metals, where electrons are shared. Ionic bonds are between a metal and a non-metal, where electrons move from metal to non-metal, and they become oppositely charged.
300
What is group 7 of the periodic table called?
What is halogens.
300
What are the units for electrical resistance, potential difference and current?
What are Ohms, Volts, and Amperes.

When something flows more slowly than water, what physical property does this describe?
What is viscosity.
400
If lithium and chlorine combine they would form a compound with formula?
What is LiCl.

400
What is a sunspot?
What is a region of the Sun's surface that is cooler than the rest of the sun.
400
The relationship between insects such as bees, and flowers?
What is mutualism

What is 31, 15, -3.
500
What is the purpose of the finger during charging by induction?
What is allows for more electrons to flow in/ out to allow the electroscope to remain charged after interaction
