Here's why this is important:
* Identity of an element: The atomic number is the defining characteristic of an element. Every atom of a particular element has the same number of protons. For example, all carbon atoms have 6 protons, and all oxygen atoms have 8 protons.
* Number of electrons in a neutral atom: In a neutral atom, the number of protons is equal to the number of electrons. This is because protons have a positive charge and electrons have a negative charge, and they need to balance each other out.
* Position on the periodic table: The periodic table is organized by increasing atomic number. This means elements with similar chemical properties are grouped together.
