Neon, a noble gas, has an atomic number of 10. This means that a neutral neon atom has 10 protons in its nucleus. Since atoms are electrically neutral, the number of electrons in a neon atom is equal to the number of protons.
Therefore, a neon atom has 10 electrons.
These electrons are arranged in two energy levels or shells. The first shell, closest to the nucleus, contains 2 electrons, while the second shell contains the remaining 8 electrons. This electron configuration gives neon its stable and inert nature, making it a part of the noble gases group in the periodic table.
