Reactivity

Front

What is reactivity in chemistry?

Back

Reactivity refers to the tendency of a substance to undergo chemical reactions, either by itself or with other materials.

Front

What makes an element stable?

Back

An element is considered stable when its outer electron shell is full, meaning it does not readily react with other elements.

Front

Why are halogens highly reactive?

Back

Halogens are highly reactive because they only need one more electron to complete their outer shell, making them eager to react with other elements.

Front

What is the trend of reactivity in alkali metals?

Back

Reactivity increases down the group in alkali metals, meaning lithium is less reactive than sodium, which is less reactive than potassium.

Front

Which metal is the least reactive: calcium, magnesium, iron, or copper?

Back

Copper is the least reactive metal among the options provided.

Front

What is the product of the reaction between zinc sulfate and magnesium?

Back

The reaction produces magnesium sulfate and zinc.

Front

What is a valence electron?

Back

Valence electrons are the electrons in the outermost shell of an atom that are involved in forming bonds with other atoms.

Front

How does the reactivity of metals compare to nonmetals?

Back

Metals tend to lose electrons and are generally more reactive than nonmetals, which tend to gain electrons.

Front

What is the significance of the periodic table in understanding reactivity?

Back

The periodic table organizes elements by increasing atomic number and groups elements with similar properties, helping predict their reactivity.

Front

What is an example of a highly reactive metal?

Back

Sodium (Na) is an example of a highly reactive metal.
