No, we cannot use a single digit for the symbol of an atom's atomic number. The atomic number represents the number of protons in an atom's nucleus, and it is typically denoted by a whole number. Atomic numbers can range from 1 to 118, representing the different elements in the periodic table.
Each element has a unique atomic number, and it is an essential characteristic that distinguishes one element from another. For example:
- Hydrogen has an atomic number of 1.
- Carbon has an atomic number of 6.
- Oxygen has an atomic number of 8.
- Gold has an atomic number of 79.
- Uranium has an atomic number of 92.
These are just a few examples of elements and their corresponding atomic numbers. As you can see, all of these atomic numbers consist of more than one digit.
