54) The atomic number is the number of protons (55) in the atomic nucleus. It is unique for each (57) element.
The atomic number is the number of protons in the nucleus of an atom. It is unique for each element.
To determine the atomic number of an element, you need to know the number of protons in its nucleus.
The atomic number of an element corresponds to the number of protons present in the nucleus of an atom. Protons are positively charged particles that reside in the nucleus. So, to find the atomic number, you can count the number of protons.
For example, if we take the element hydrogen, the atomic number is 1. This means that there is one proton in the nucleus of a hydrogen atom. Similarly, if we consider the element carbon, the atomic number is 6, indicating that there are six protons in a carbon atom's nucleus.
Remember, the atomic number is unique to each element. It is what distinguishes one element from another on the periodic table.
