Step 2:: Definition of Atomic Number
The atomic number represents the number of protons in the nucleus of an atom of a specific element. This is a fundamental characteristic that uniquely identifies each chemical element.
Step 3:: Significance in the Periodic Table
Z = \text{number of protons}
Where Z represents the atomic number, this number determines: - The element's identity - The element's position in the periodic table - The number of electrons in a neutral atom
Step 4:: Relationship to Atomic Structure
- Each proton carries a positive charge of $$+1$$ elementary charge unit
- In a neutral atom, the number of protons equals the number of electrons - The atomic number determines the chemical properties of the element
Step 5:: Examples
- Oxygen: $$Z = 8$$ (8 protons)
- Carbon: Z = 6 (6 protons)
Final Answer
The atomic number represents the number of protons in an atom's nucleus, which uniquely identifies the chemical element and determines its fundamental chemical properties.
