The atomic number of an element can be found by referring to the periodic table of elements. The atomic number represents the number of protons present in the nucleus of an atom of a specific element.
Here's how you can find the atomic number of an element:
Locate the element on the periodic table. The periodic table organizes elements in order of increasing atomic number.
The atomic number is typically displayed as a whole number above or below the element's symbol. For example, hydrogen (H) has an atomic number of 1, helium (He) has an atomic number of 2, and so on.
The atomic number uniquely identifies each element and determines its position in the periodic table.
It's worth noting that the atomic number is also equal to the number of electrons in a neutral atom of that element, assuming no charge or ionization has occurred.
