Periodic Table Concepts and Electron Configuration

Front

What is a Group in the periodic table?

Back

A Group is a vertical column in the periodic table where elements have similar chemical properties.

Front

What is a Period in the periodic table?

Back

A Period is a horizontal row in the periodic table that indicates the number of electron shells an element has.

Front

Where are Valence electrons located?

Back

Valence electrons are located in the outmost shell of an atom.

Front

What are Valence electrons?

Back

Valence electrons are the electrons in the outermost shell of an atom that are involved in chemical bonding.

Front

How many Valence electrons does Aluminum have?

Back

Aluminum has 3 valence electrons.

Front

What is the significance of Valence electrons?

Back

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

Front

What element is in Group 9, Period 4 of the periodic table?

Back

Cobalt is in Group 9, Period 4.

Front

What is the atomic number of an element?

Back

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

Front

What is the relationship between Groups and chemical properties?

Back

Elements in the same Group have similar chemical properties due to having the same number of valence electrons.

Front

What is the difference between metals and nonmetals in the periodic table?

Back

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