Front

What is the Periodic Table?

Back

A tabular arrangement of chemical elements, organized by increasing atomic number, electron configuration, and recurring chemical properties.

What does the term 'Period' refer to in the Periodic Table?

Back

A horizontal row in the Periodic Table where elements have the same number of electron shells.

Front

What does the term 'Group' refer to in the Periodic Table?

Back

A vertical column in the Periodic Table where elements have similar chemical properties and the same number of valence electrons.

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 significance of the atomic number?

Back

The atomic number represents the number of protons in an atom's nucleus and determines the element's identity.

Front

What does the symbol 'Ra' represent?

Back

Radium, a radioactive element in the alkaline earth metals group.

Front

What are Halogens?

Back

Elements in group 17 of the Periodic Table, known for being highly reactive nonmetals.

Front

What is a noble gas?

Back

Elements in group 18 of the Periodic Table, characterized by their lack of reactivity due to having a full valence shell.

Front

What does it mean if an element is radioactive?

Back

It means the element's nucleus is unstable and can emit radiation as it decays.

Front

What is the difference between metals and nonmetals?

Back

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