Front

What is the organization principle of the Periodic Table?

Back

The Periodic Table is organized by increasing atomic number.

Front

What are the metals in the middle of the Periodic Table called, whose properties change from metallic to nonmetallic?

Back

Transition metals.

Front

What is the name of Group 14 in the Periodic Table, which contains one nonmetal, two metalloids, and two metals with 4 valence electrons?

Back

Carbon Group.

Front

What are the characteristics of Group 17 elements in the Periodic Table?

Back

Group 17 elements are all nonmetals, very reactive, poor conductors of heat and electricity, and tend to form salts with metals.

Front

What is the significance of valence electrons in determining the reactivity of elements?

Back

Valence electrons determine how an element will react with others; elements with similar valence electron configurations tend to exhibit similar chemical properties.

Front

What is the general trend in reactivity for metals as you move down a group in the Periodic Table?

Back

Reactivity of metals generally increases as you move down a group in the Periodic Table.

Front

What is the general trend in reactivity for nonmetals as you move down a group in the Periodic Table?

Back

Reactivity of nonmetals generally decreases as you move down a group in the Periodic Table.

Front

What is the term for elements that have properties of both metals and nonmetals?

Back
