Reading the Table
This number, found above the element symbol, represents the number of protons in an atom of the element.
What is the atomic number?
This class of elements, found on the left side of the periodic table, is shiny, conducts electricity, and is malleable.
What are metals?
This term refers to the electrons in the outermost energy level of an atom, responsible for chemical bonding.
What are valence electrons?
This type of diagram uses dots around an element's symbol to represent its valence electrons.
What is an electron dot diagram?
Four properties of metals.
What is high melting point, ductile, good conductor of heat, shiny, and/or malleable?
This term describes the vertical columns on the periodic table that group elements with similar chemical properties
What are groups?
This class of elements have properties of both metals and nonmetals.
What are metalloids?
This group on the periodic table, also known as the noble gases, has a full outer shell of valence electrons.
What is Group 18?
In an electron dot diagram, this group of elements typically has eight dots around their symbol.
What are noble gases?
Four properties of nonmetals.
What is low boiling point, poor conductor of heat, not shiny, and brittle?
This block of the periodic table, which includes elements like gold and iron, is known for containing metals with variable oxidation states.
What is the transition metals?
This nonmetal group in Group 17 is known for being highly reactive and forming salts with metals.
What are halogens?
An element in Group 1, like sodium, has this many valence electrons.

What are non-reactive, low boiling point, colorless, and odorless?
The horizontal rows on the periodic table are called this, and they indicate the number of electron shells in an atom.
What are periods?
This term refers to elements like helium, neon, and argon, known for being chemically inert under standard conditions.

What is highly reactive, solid at room temperature, low in density, and relatively soft?
In the periodic table, elements are primarily arranged in order of increasing value of this property.
What is atomic number?
These metallic elements in Groups 3 through 12 are often characterized by their ability to form colorful compounds due to partially filled d-orbitals.
What are transition metals?
The number of valence electrons in Helium.
What is two?
For elements in group 2, the number of dots in their electron dot diagram is this.
What is two?
Four properties of alkaline earth metals.
What are silver/gray, low in density, relatively soft, and fairly reactive (but not as much as alkali metals?
