Front

What is the reactivity trend of Group 1 metals?

Back

Group 1 metals are the most reactive metals, with reactivity increasing down the group.

Front

What are the characteristics of metals?

Back

Metals are typically shiny, silvery solids that are good conductors of heat and electricity.

Front

What is the definition of a Bohr Model?

Back

A Bohr Model is a simple diagram that shows the atomic structure of an atom, depicting electrons in defined orbits around the nucleus.

Front

What is the significance of the periodic table in chemistry?

Back

What are transition metals?

Back

Transition metals are 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, malleable, and good conductors, while nonmetals are usually dull, brittle, and poor conductors.

Front

What are noble gases and where are they located in the periodic table?

Back

Noble gases are located in Group 18 of the periodic table and are known for their lack of reactivity due to having a full valence shell.
