Elements in the same family have similar appearances and chemical properties.

Front

Which type of elements tend to be good conductors of heat and electricity?

Back

Metals are good conductors of heat and electricity.

Front

What are the seven elements called that are not metals but have properties of both metals and nonmetals?

Back

These elements are called semi conductors or metalloids.

Front

True or False: Mendeleev arranged his periodic table by increasing atomic number.

Back

False. Mendeleev arranged his periodic table by increasing atomic mass.

Front

What did Mendeleev study in order to arrange the periodic table?

Back

Mendeleev studied properties, reactions, and patterns of elements.

Front

What is the periodic law?

Back

The periodic law states that the properties of elements are a periodic function of their atomic numbers.

Front

Define 'metalloids'.

Back

Metalloids are elements that have properties intermediate between metals and nonmetals.

Front

What is the significance of the periodic table?

Back

The periodic table organizes elements based on their atomic number, electron configuration, and recurring chemical properties.

Front

What are alkali metals?

Back

Alkali metals are the elements in group 1 of the periodic table, known for being highly reactive.

Front

What are noble gases?

Back

Noble gases are the elements in group 18 of the periodic table, known for their lack of reactivity due to having a full valence shell.
