100
Which way to periods run, left to right, or top to bottom?
What is left to right
100
What does APE stand for?

100
Is sulfer a metal, non-metal, or metalloid?
What is Non-metal
100
The law of conservation of mass states...
What is matter cannot be created nor destroyed
200
The sub-atomic particle that has a negative charge
What is electron
200
Which groups are the most reactive?
What is group 1 and 17
200
Using your white board, draw a bohr model of Hydrogen labeling all parts AND their charges.
1 positive proton inside the nucleus, and 1 negative electron outside the nucleus
200
Which group is non-reactive?
What is Nobel-gases
200
Is this equation balanced? NaPO3 --> NaH2P2O4 Explain why or why not.
What is no because there are only 1 P on the reactants side and 2 on the products.
300
The sub atomic particle that has a neutral charge
What is Neutrons
300
Which group is non-reactive?
What is group 8 or 18
300
An atom with 6 protons, 6 neutrons, and 6 electrons is of what element?
What is Carbon
300
Which element is on the left side of the periodic table but it NOT a metal
What is Hydrogen
300
Is this equation balanced or unbalanced? Why or why not? Fe2 + 2O2 --> Fe4O4
What is Unbalanced because there is only 2 iron on the reactants and 4 on the products.
400
What are the 2 sub-atomic particles that make up the primary mass of the atom?
What is Protons and neutrons
400
True or false: Elements in the same period have similar chemical properties
What is False
400
How do you calculate how many neutrons an element has?
What is using MAN: Mass - Atomic number = # of Neutrons.
400
