How is the Modern Periodic Table of Elements arranged?

Back

The Modern Periodic Table is arranged by atomic number, which is the number of protons in an atom's nucleus.

Front

What group of metals are the second most reactive?

Back

Alkaline Earth Metals are the group of metals that are the second most reactive.

Front

What is a period in the context of the periodic table?

Back

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

Front

What are semiconductors?

Back

Semiconductors are materials that have conductivity between that of insulators and conductors, often associated with metalloids.

Front

What is the significance of atomic number in the periodic table?

Back

The atomic number determines the position of an element in the periodic table and defines the element's identity.

Front

What are the properties of metals?

Back

Metals are typically shiny, malleable, ductile, and good conductors of heat and electricity.

Front

What are nonmetals?

Back

Nonmetals are elements that lack metallic properties, are usually poor conductors, and can be gases, liquids, or brittle solids.

Front

What is a group in the periodic table?

Back

A group is a vertical column in the periodic table, containing elements with similar chemical properties.

Front

What are alkali metals?

Back

Alkali metals are highly reactive metals found in Group 1 of the periodic table, including lithium, sodium, and potassium.
