Key Concepts

Atomic Number

The atomic number represents the number of protons in the nucleus of an atom. It uniquely identifies an element and determines its position on the periodic table.

Protons

Protons are positively charged particles located in the nucleus of an atom. Their number, given by the atomic number, defines the identity of the element and contributes to the overall positive charge of the nucleus.

Electrons

Electrons are negatively charged particles that orbit the nucleus in various energy levels. In a neutral atom, the number of electrons equals the number of protons, balancing the overall electrical charge.

Alkali Metals

Alkali metals are a group of elements found in Group 1 of the periodic table. These elements, including sodium and potassium, are characterized by having one valence electron which makes them highly reactive and gives them distinct chemical properties.
