The Periodic Table
These are vertical columns on the periodic table, and can tell you how many valence electrons an atom has.
What are groups?
These are the subatomic particles in an atom that have a negative charge.
What are electrons?
This type of element the most common on the periodic table and is typically shiny, malleable, and can conduct electricity.
What is a metal?
This change can often be reversed by simple physical means.
What is a physical change?
Number of protons increases as you go these two ways across the periodic table.
What are right and down?
These are horizontal rows on the periodic table, and can tell you how many electron shells are in an atom.
What are periods?
What is an ion?
This type of element is typically dull in luster, brittle, and a gas at room temperature.
What are nonmetals?
This change alters the chemical composition of a substance.
What is a chemical change?
The amount of energy levels of an element increases as you go this way on the periodic table.
What is down?
These are collections of elements on the periodic table that are grouped together because of their similar properties. Example: metal or halogen.
What are families?
This type of electron is in the farthest cloud from the nucleus. These also have more energy than the closer electrons.
What are valence electrons?
This type of element has properties of both metals and non-metals.
What are metalloids?
The sun employs this type of change to release heat and light.
What a chemical change?
Metals are more common as you go this way across the periodic table.
What is left?
This zigzagging line separates metals from nonmetals.
This is the name of an atom with an abnormal number of neutrons in its nucleus.
What is an isotope?
This is a term used to mean that the element can be made into a thin wire relatively easily.
What is ductile?
A baking soda and vinegar volcano employs this type of change.
What is a chemical change?
Valence electron number increases as you go this way across the periodic table.
What is right?
These two families of elements are separated from the rest of the periodic table.
What are lanthanides and actinides?
As the number of electrons in an atom increases, the atomic radius does this.
What is decreases?
What metalloid is commonly used to make computer chips?
What is silicon?
Boiling water is this type of change.
What is a physical change?
When you go these two directions on the periodic table, electronegativity decreases.
