What is the Periodic Table?

Back

A tabular arrangement of chemical elements, organized by increasing atomic number, where elements with similar properties are grouped together.

What does 'atomic number' represent?

Back

The number of protons in the nucleus of an atom, which determines the element's identity.

Front

What is a group in the Periodic Table?

Back

A vertical column in the Periodic Table that contains elements with similar chemical properties.

A horizontal row in the Periodic Table that indicates the number of electron shells in the elements.

Front

Which group contains the alkaline earth metals?

Back

Group 2.

Front

What is the significance of the position of an element in the Periodic Table?

Back

It helps predict the element's properties and reactivity based on its group and period.

Front

What are transition metals?

Back

Elements found in groups 3-12 of the Periodic Table, known for their ability to form variable oxidation states and colored compounds.

Front

What is the difference between metals and nonmetals?

Back

Metals are typically shiny, conductive, and malleable, while nonmetals are dull, insulative, and brittle.

Front

What is an isotope?

Back

Atoms of the same element that have the same number of protons but different numbers of neutrons.

Front

What is the role of valence electrons?

Back

Valence electrons determine how an element reacts chemically with other elements.
