What is a metalloid?

Back

A metalloid is an element that has properties of both metals and nonmetals. Examples include silicon and germanium.

Front

Which group in the periodic table contains alkali metals?

Back

Group I (1) contains alkali metals, which include lithium, sodium, potassium, rubidium, cesium, and francium.

Front

What type of bond holds diatomic molecules together?

Back

Diatomic molecules are held together by pure covalent bonds, where electrons are shared equally between the atoms.

Front

Which bond is the most polar: H-F, H-Cl, H-Br, or H-I?

Back

The H-F bond is the most polar due to the significant difference in electronegativity between hydrogen and fluorine.

Front

What is a cation?

Back

A cation is an ion with a positive charge, formed when an atom loses one or more electrons.

Front

What is the definition of an anion?

Back

An anion is an ion with a negative charge, formed when an atom gains one or more electrons.

Front

What are the main characteristics of metals?

Back

Metals are typically shiny, good conductors of heat and electricity, malleable, and ductile.

Front

What are the main characteristics of nonmetals?

Back

Nonmetals are usually dull, poor conductors of heat and electricity, and can be gases, liquids, or brittle solids.

Front

What is electronegativity?

Back

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

Front

What is the significance of the periodic table?

Back

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