What is a metalloid?

Back

A metalloid is an element that has properties of both metals and nonmetals. They are typically semiconductors of electricity.

Front

Where are nonmetals located on the Periodic Table?

Back

Nonmetals are located on the right side of the Periodic Table.

Front

What is the significance of the zig-zag line on the Periodic Table?

Back

The zig-zag line separates metals from nonmetals, with metalloids located along the line.

Front

What is electronegativity?

Back

Electronegativity is a measure of an atom's ability to attract and hold onto electrons.

Front

Which element has the highest electronegativity?

Back

Fluorine has the highest electronegativity of all elements.

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 ionization energy?

Back

Ionization energy is the energy required to remove an electron from an atom in its gaseous state.

Front

What is the trend of electronegativity in the Periodic Table?

Back

Electronegativity increases from left to right across a period and decreases from top to bottom in a group.

Front

What are the properties of nonmetals?

Back

Nonmetals are typically poor conductors of heat and electricity, have high ionization energies, and are not malleable or ductile.

Front

What is the difference between metals and nonmetals?

Back

Metals are generally good conductors of heat and electricity, malleable, and ductile, while nonmetals are poor conductors and brittle.
