Front

What does the Periodic Law state about elements in the same group?

Back

Elements in the same group will have similar chemical and physical characteristics.

Front

True or False: The elements B, Si, As, and Sb exhibit traits of both metals and non-metals.

Back

True

Front

How are periods organized in the periodic table?

Back

Periods (left to right) are organized by their atomic number.

Front

List the evolution of our understanding of basic atomic structure from earliest to most recent.

Back

B, A, C, D

Front

What is false regarding electronegativity in the periodic table?

Back

Electronegativity decreases as we move to the left of the periodic table.

Front

What are the main groups of elements in the periodic table?

Back

The main groups are metals, nonmetals, and metalloids.

Front

Define electronegativity.

Back

Electronegativity is the tendency of an atom to attract electrons in a chemical bond.

Front

What trend is observed in electronegativity across a period?

Back

Electronegativity increases as you move from left to right across a period.

Front

What trend is observed in electronegativity down a group?

Back

Electronegativity decreases as you move down a group.

Front

What are metalloids and where are they located in the periodic table?

Back

Metalloids have properties of both metals and nonmetals and are located along the zig-zag line in the periodic table.
