The atomic number (Z) of an atom represents the number of protons in its nucleus, defining the element's identity and determining its chemical properties.
The atomic number (Z) of an atom represents the number of protons in its nucleus, defining the element’s identity and determining its chemical properties.
It is essential for all atoms of the same element to have the same atomic number because it uniquely identifies the element by indicating the number of protons in the nucleus, which determines its chemical properties and distinguishes it from other elements.

The atomic number varies across different elements, increasing sequentially from one element to the next in the periodic table. It represents the number of protons in an atom's nucleus and determines the element's identity.

The atomic number of hydrogen is 1 because it has one proton in its nucleus, defining its identity. This unique characteristic distinguishes hydrogen from other elements in the periodic table.
The atomic number of hydrogen is 1 because it has one proton in its nucleus, defining its identity. This unique characteristic distinguishes hydrogen from other elements in the periodic table.
