Periodic Table

Valence electrons are the electrons in the outermost shell of an atom that are involved in forming bonds with other atoms.

Elements in Group 2 have 2 valence electrons.

Group 1 is known as the alkali metals.

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

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

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

The periodic table organizes elements based on their atomic number, electron configuration, and recurring chemical properties.

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.

Metals are typically shiny, malleable, and good conductors, while nonmetals are usually dull, brittle, and poor conductors.

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.
