This is approx. equal to the number of protons and neutrons in an atom.
What is atomic mass?
This decreases are you move from left to right across the periodic table
What is reactivity?
Columns on the periodic table. Can be used to determine valence electrons.
What is a group?
Rows on the periodic table. Can be used to determine number of energy levels.
What is a period?
This subatomic particle determines the element.
What are protons?
Electrons located in the outermost shell. Determine reactivity.
What are valence electrons?
Dull, brittle, poor conductors of heat and electricity.
What are non-metals?
This is the amount of valence electrons in group 13.
What is three valence electrons?
As you move across a period this number always increases by one.
Hint: ALWAYS!
What is atomic number?
This element takes, shares and gives its valence electron.
A pure substance that cannot be separated into smaller substance by physical or chemical change.
What is an element?
What are metalloids?
This happens to energy levels as you move down a group.
What is increases?
The amount of periods on the periodic table.
What is 7?
I have two energy levels and a mass half of Calcium.
What is Neon?
The one or two letter icon used to represent an element.
What is chemical symbol?
I am the scientist credited with the arrangement of the Periodic Table.
Who is Dmitri Mendeleev?
This family reacts with the Boron Family.
What is the Nitrogen Family?
This period has elements with less than 55 protons but more than 36 protons.
What is period 5?
This element is a halogen with more mass than Ag but a lesser mass than Radon.
What is Iodine?
Non-reactive, odorless, colorless, glow when struck with electricity, full.
What are Noble Gasses?
The place where a group and a period intersect.
What is an element?
This highly reactive metal group reacts with a reactive non-metal group.
What are Alkali Metals and Halogens?
We are a period within a period, but not really. We are metals. We are the second one.
What is the Actinide Aeries?
This element has a mass greater than Arsenic, less than Bismuth and has 5 valence electrons.
What is Antimony?
