This question is incomplete because it is lacking the necessary answer options, which I have provided below:

A. Alkaline earth metal; alkali metal; transition metal.

B. Alkali metal; transition metal; alkaline earth metal.

C. Alkali metal; alkaline earth metal; transition metal.

D. Transition metal; alkaline earth metal; alkali metal

So, given your question, the list which has the classes of chemical elements in order from most reactive to least reactive is: C. Alkali metal; alkaline earth metal; transition metal.

A chemical property refers to the properties of a chemical element or compound (substance) that is observable and measurable during a chemical reaction.

Some examples of the chemical properties of a chemical element or compound (substance) are;

Tarnishing.

Rusting.

Flammability.

Acidity.

Chemical reactivity.

Chemical reactivity is a chemical property that determines how readily a chemical element bonds with other chemical elements, in order to form a new chemical compound (substance).

As a general rule, the ability of a chemical element to bond with other chemical elements is highly (largely) dependent on the number of valence electrons in the outermost shell of its atom.

Hence, chemical elements with fewer number of valence electrons are the most reactive while those with more valence electrons are least reactive.

Alkali metals = 1 valence electrons.

Alkaline earth metal = 2 valence electrons.

Transition metal = 2 valence electrons.

From the above description, we can deduce that the classes of chemical elements in order from most reactive to least reactive is: Alkali metal, alkaline earth metal and transition metal.

Answer:

The financial crisis is the breakdown of trust that occurred between banks the year before the 2008 financial crisis. It was caused by the subprime mortgage crisis, which itself was caused by the unregulated use of derivatives. The major causes of the initial subprime mortgage crisis and following recession include international trade imbalances and lax lending standards contributing to high levels of developed country household debt and real-estate bubbles that have since burst; U.S. government housing policies; and limited regulation of non-depository financial institutions.

The imposition of "Death Penalty" by NCAA Forces a school to eliminate a sport which they face the punishment for, which can be a year or more depending on NCAA.
