Ch. 5 Periodic Law Review

Front

What is the significance of valence electrons in determining the reactivity of an element?

Back

Valence electrons are the outermost electrons of an atom and play a crucial role in chemical reactions. The number of valence electrons determines how an element will bond with others, influencing its reactivity.

Front

Which group in the periodic table contains the most reactive metals?

Back

The Alkali Metals, found in Group 1 of the periodic table, are the most reactive metals.

Front

How many elements are in a period where only the s and p sublevels are completely filled?

Back

There are 8 elements in such a period, corresponding to the filling of the s and p sublevels.

Front

What type of metal is gold, which is located in Group 11 of the periodic table?

Back

Gold is classified as a Transition Metal.

Front

Which element has a larger atomic radius, Strontium or Zinc?

Back

Strontium has a larger atomic radius than Zinc.

Front

What are the characteristics of Alkali Metals?

Back

Alkali Metals are highly reactive, have one valence electron, and are found in Group 1 of the periodic table.

Front

Define the term 'period' in the context of the periodic table.

Back

A period is a horizontal row in the periodic table, indicating elements with the same number of electron shells.

Front

What is the general trend in atomic radius as you move down a group in the periodic table?

Back

The atomic radius increases as you move down a group due to the addition of electron shells.

Front

What is the relationship between the number of valence electrons and the group number in the periodic table?

Back

The group number often indicates the number of valence electrons for main group elements; for example, Group 1 has 1 valence electron, Group 2 has 2, and so on.

Front

What distinguishes Transition Metals from other metals in the periodic table?

Back

Transition Metals are characterized by their ability to form variable oxidation states and to form colored compounds.
