I am confused? Do I look at somewhere on the periodic table? For example for the noble gas items argon, radon, helium, and neon?
The number of shells in a noble gas can be determined by looking at its electron configuration. Each shell can hold a certain number of electrons, and the number of shells needed to hold all of the noble gas's electrons is the same as the number of shells in the noble gas.
The electron configuration of noble gases follows the pattern of 2, 8, 18, 32, etc. This means that the first shell can hold 2 electrons, the second shell can hold 8 electrons, the third shell can hold 18 electrons, and so on.
Noble gases have more shells compared to other elements because they are located in the last column of the periodic table. This means they have a full outer shell and can hold more electrons in lower shells.
No, the number of shells in a noble gas cannot change. This is because the number of shells is determined by the number of electrons in the noble gas and that is a fundamental characteristic of the element.
The number of shells in a noble gas directly affects its reactivity. Noble gases have a full outer shell, making them stable and unreactive. This is because they do not need to gain or lose electrons to achieve a stable electron configuration, unlike other elements.
