What is the shape of a tetrahedral molecule?

Back

A tetrahedral molecule has four bonds arranged around a central atom, forming a three-dimensional shape with bond angles of approximately 109.5 degrees.

Front

What are delocalized electrons?

Back

Delocalized electrons are electrons in a molecule that are not associated with a single atom or bond and can move freely throughout the structure, typically found in metals.

Front

What type of reaction is a combination (or synthesis) reaction?

Back

A combination reaction is a chemical reaction where two or more substances combine to form a single product.

Front

What is the oxidation number?

Back

The oxidation number is a measure of the degree of oxidation of an atom in a substance, indicating the number of electrons lost or gained.

Front

What is a linear molecular shape?

Back

A linear molecular shape occurs when atoms are arranged in a straight line, typically with bond angles of 180 degrees.

Front

What is a bent molecular shape?

Back

A bent molecular shape occurs when the central atom has lone pairs, causing the bond angle to be less than 180 degrees.

Front

What is a trigonal pyramidal molecular shape?

Back

A trigonal pyramidal shape occurs when a central atom is bonded to three other atoms and has one lone pair, resulting in a pyramid-like structure.

Front

What is a decomposition reaction?

Back

A decomposition reaction is a chemical reaction where a single compound breaks down into two or more simpler products.

Front

What is a single replacement reaction?

Back

A single replacement reaction is a chemical reaction where one element replaces another element in a compound.
