Periodic Table Review

Front

What is a transition metal?

Back

Transition metals are elements found in groups 3-12 of the periodic table, characterized by their ability to form variable oxidation states and colored compounds. Example: Iron (Fe) is a transition metal.

Where are the metalloids located on the Periodic Table?

Back

Metalloids are located on the stairsteps of the periodic table, which separates metals from nonmetals.

Front

How many valence electrons do halogens have?

Back

Halogens have 7 valence electrons, which makes them highly reactive.

Front

What defines elements in the same period on the Periodic Table?

Back

Elements in the same period have the same number of electron shells. For example, Sn (Tin) and Rb (Rubidium) are in the same period.

Front

What is an Alkaline Earth Metal?

Back

Alkaline Earth Metals are elements in group 2 of the periodic table, known for having two valence electrons. Example: Calcium (Ca) is an Alkaline Earth Metal.

Front

What is the atomic number of an element?

Back

The atomic number is the number of protons in the nucleus of an atom, which determines the element's identity.

Front

What are noble gases?

Back

Noble gases are elements in group 18 of the periodic table, known for their lack of reactivity due to having a full valence shell. Example: Neon (Ne) is a noble gas.

Front

What is the significance of the periodic law?

Back

The periodic law states that the properties of elements are a periodic function of their atomic numbers, leading to the organization of the periodic table.

Front

What are alkali metals?

Back

Alkali metals are elements in group 1 of the periodic table, characterized by having one valence electron and being highly reactive. Example: Lithium (Li) is an alkali metal.

Front

What is the difference between metals and nonmetals?

Back

Metals are typically shiny, conductive, and malleable, while nonmetals are dull, insulative, and brittle.
