Key Points
- Atomic number
- It is the number of a chemical element in the periodic system, whereby the elements are arranged in order of increasing the number of protons in the nucleus.
- Accordingly, the number of protons, which is always equal to the number of electrons in the neutral atom, is also the atomic number.
- The atomic number (Z) of an element is the number of protons in the nucleus of each atom of that element. Hence, Option 2 is correct.
- This means that the number of protons is the characteristic that makes each element unique compared to all other elements.
- Elements are different because of their atomic number.
- The periodic table displays all of the known elements and is arranged in order of increasing atomic number.
- In this table, an element’s atomic number is indicated above the elemental symbol.
