Multiple Choice

Which of the following best describes metalloids?

• Elements that are dull and poor conductors, often gases or brittle solids

• Elements with properties of both metals and nonmetals, found along the 'staircase' line

• Electrons in the outermost shell of an atom

Multiple Choice

Which of the following best describes an ion?

• An atom with a positive or negative charge due to gaining or losing electrons

• The arrangement of electrons in energy levels

• How easily an element combines with others

• A way to categorize elements by color

Open Ended

Open Ended

After learning about metals, nonmetals, metalloids, and valence electrons, what questions do you still have about the periodic table or its elements?

Multiple Choice

Which of the following best describes the role of valence electrons in chemical bonding?

• They determine how an element bonds with others.

• They are responsible for the color of the element.

• They are found in the nucleus of the atom.

• They make elements shiny and conductive.

Multiple Choice

Which step in reading the periodic table helps you identify whether an element is a metal, nonmetal, or metalloid?

• Find the element's square

• Identify metals, nonmetals & metalloids

• Understand atomic mass

• Count valence electrons by group
