True
100
What is half-life?
What is the time taken for the radioactivity of an isotope to decrease to half its original value
100
Who created the first atomic theory?
Who is John Dalton
100

Au, Ag, Si, N
What is Au
200
What are the main groups of the table?
What are:
Group 1: alkali metals

200
Why would metals be better at making wires than non-metals? Give two examples
1. Metals are ductile
2. Metals are conductive
200
Why are atomic masses on the periodic table in decimal form?
Because they are a weighted average of all the isotopes’ masses
200

Who is Rutherford
200
Draw a Lewis Dot Diagram for Oxygen
300

300
Write the simplified electron configuration of Calcium
What is 2-8-8-2
300
Who discovered electrons?
Who is J. J. Thomson
300
What Element does this Lewis Dot Diagram represent?
What is Fluorine
400
As electronegativity moves across a period, it:
What is Increases
400
Why do some atoms form covalent bonds?
What is they have the same electronegativity levels
400
The half-life of Zn-71 is 2.4 minutes. If one had 100.0g at the beginning, how many grams would be left after 7.2 minutes has elapsed?
7.2 / 2.4 = 3 half-lives
(1/2)3 = 0.125 (the amount remaining after 3 half-lives)
100.0 g x 0.125 = 12.5 g remaining
