Unit 3 Test (Part 1) RETAKE TEST: Periodic Table

Front

What is the most likely behavior of Fluorine (F) when combining with another element?

Back

Fluorine (F) is most likely to gain electrons.

Front

Why did Mendeleev leave blank spaces in his Periodic Table?

Back

He thought elements would be discovered to fit into those spaces.

Front

Which element is considered a metalloid based on its location on the Periodic Table?

Back

Silicon (Si) is considered a metalloid.

Front

Which element has the best chance of reacting with hydrochloric acid (HCl)?

Back

Potassium (K) has the best chance of reacting with hydrochloric acid.

Front

How many valence electrons does Magnesium (Mg) have?

Back

Magnesium (Mg) has 2 valence electrons.

Front

What are valence electrons?

Back

Valence electrons are the electrons in the outermost shell of an atom that are involved in chemical bonding.

Front

What is the significance of the Periodic Table in chemistry?

Back

The Periodic Table organizes elements based on their atomic number, electron configuration, and recurring chemical properties.

Front

What are metalloids?

Back

Metalloids are elements that have properties of both metals and nonmetals, typically found along the zig-zag line on the Periodic Table.

Front

What is the general trend of electronegativity in the Periodic Table?

Back

Electronegativity increases across a period from left to right and decreases down a group.

Front

What is the role of noble gases in the Periodic Table?

Back

Noble gases are inert and do not readily react with other elements due to their full valence electron shell.
