CPC Unit 5 True or False

Front

Most metals are ductile.

Back

True: Ductility is a property of metals that allows them to be drawn into wires without breaking.

Front

The ending -ide is used to designate an anion.

Back

True: The suffix -ide is commonly used in chemistry to indicate that a compound contains an anion.

Front

Metals are poor conductors.

Back

False: Metals are generally good conductors of heat and electricity due to the presence of free-moving electrons.

Front

A positively charged ion is called an anion.

Back

False: A positively charged ion is called a cation, while an anion is negatively charged.

Front

Elements in group 1 lose their one valence electron, forming an ion with a 1+ charge.

Back

True: Group 1 elements, such as sodium and potassium, lose one electron to form cations with a +1 charge.

Front

What is ductility?

Back

Ductility is the ability of a material to deform under tensile stress, often characterized by the material's ability to be stretched into a wire.

Front

Define anion.

Back

An anion is a negatively charged ion that is formed when an atom gains one or more electrons.

Front

What is a cation?

Back

A cation is a positively charged ion that is formed when an atom loses one or more electrons.

Front

What does the suffix -ate indicate in chemistry?

Back

The suffix -ate is used to denote a polyatomic ion that contains oxygen, typically in a higher oxidation state.

Front

What is the significance of valence electrons?

Back

Valence electrons are the outermost electrons of an atom and are crucial in determining how an atom bonds with others.
