Distribution of Electrons in an Atom of Element with Atomic Number 18
- The atomic number of the given element is 18, which means it has 18 electrons.
- The electrons are distributed in different energy levels or shells around the nucleus.
- The first shell can hold a maximum of 2 electrons, the second can hold 8, and the third can hold 8 as well.
- Therefore, the electron configuration of this element is 2, 8, 8.
- The first shell is completely filled with 2 electrons, the second shell is also completely filled with 8 electrons, and the remaining 8 electrons are in the third shell.
Special Nature of the Outer Shell of the Atom
- The outermost shell of the atom of this element is the third shell, which has 8 electrons.
- This outermost shell is also known as the valence shell.
- The valence electrons in the outermost shell of an atom are responsible for its chemical properties and reactivity.
- In the case of this element, the valence shell is completely filled with 8 electrons, making it stable and unreactive.
- Elements with completely filled valence shells are called noble gases.
- The noble gases are highly unreactive because they have no tendency to gain or lose electrons to form chemical bonds.
- Therefore, the special nature of the outer shell of the atom of this element is that it is completely filled with electrons, making it stable and unreactive like the noble gases.
In summary, the atom of the given element with atomic number 18 has 18 electrons distributed in different shells, with the outermost shell completely filled with 8 electrons, making it stable and unreactive like the noble gases.
