An example of atomic numbers is hydrogen, which has an atomic number of 1. Another example is oxygen, which has an atomic number of 8. Atomic numbers represent the number of protons in the nucleus of an atom.
The atomic number of boron is 5.
The numbers on the periodic table, known as atomic numbers, are ordered based on the number of protons in an atom's nucleus. This arrangement follows a pattern that groups elements with similar properties together. The atomic number increases from left to right and top to bottom across the periodic table.
The big numbers on the periodic table are called atomic numbers. They represent the number of protons in the nucleus of an atom, which determines the element's identity.
No. By definition isotopes of an element have the same number of protons (that is what makes them uranium, for example) but different numbers of neutrons (neutral particules in the nucleus which provide mass).
Isotopes are atoms with the same number of protons (atomic number) but different numbers of neutrons, resulting in different mass numbers. For example, carbon-12 and carbon-14 are isotopes of carbon.
