first energy level.
The first energy level can hold up to 2 electrons, the second energy level can hold up to 8 electrons, the third energy level can hold up to 18 electrons, and the fourth energy level can hold up to 32 electrons.
In the main energy level two (n=2), there are two sublevels: the 2s and 2p sublevels. The 2s sublevel can hold a maximum of 2 electrons, while the 2p sublevel can hold up to 6 electrons, allowing for a total of 8 electrons in the second energy level.
The first energy level can hold up to 2 electrons, the second can hold up to 8 electrons, the third can hold up to 18 electrons, and the fourth can hold up to 32 electrons, following the 2n^2 rule where n is the energy level number.
The s sublevel in the third main energy level is indicated by 3s.
The energy level within a shell corresponds to the main energy level of an electron in an atom. Electrons in the same shell have similar energy levels, which increase with distance from the nucleus. Each shell can hold a specific number of electrons based on its energy level.
A stairway is a good model for the energy levels in an atom because there is a 'main floor' ( the nucleus ) and steps ( the energy levels ). The nucleus is the start of the stairway of the energy levels, and the other energy levels go off of the nucleus. The first energy level can hold 2 electrons, the second energy level can hold 8. The third energy level can hold 18, and the fourth energy level can hold 32 electrons. In order for an element to be as stable as a noble gas, the outermost energy level has to be full, so sometimes an atom will gain or lose electrons to fill it's outer energy level. Other times it might share electrons with other atoms, so that they don't have to gain or lose a lot of electrons. An example of this would be H2O ( water ). There is one oxygen atom with two hydrogen atoms connected to it, and sharing their electrons with each other.
32 electrons
first energy level contains only S shell that can accomadate 2 electrons where as 2nd energy level contains S shell and P shell as well which can accomadate 2 and 6(3X2) electrons respectively..so the answer is 8 for 2nd energy level. (or) No.of electrons in any main energy level = 2n2 Here n = orbit (or energy level) number In our question , n = 2 No.of electrons in 2nd energy level = 2(2)2 = 8
The valence electron level with the greatest amount of reactive energy is typically the outermost shell, which corresponds to the highest principal energy level (n). This level can hold a maximum of 8 electrons, following the octet rule for main group elements, although the first energy level can only hold 2 electrons. Elements with fewer electrons in this level tend to be more reactive, as they seek to achieve a stable electron configuration. The reactivity generally increases as you move down a group in the periodic table, particularly for alkali and halogen elements.

To determine how many more elections are needed to fill the outermost energy level of an atom, you need to know the number of electrons already present in that level and the maximum capacity of that level. The outermost energy level can hold a maximum of 8 electrons (following the octet rule) for main group elements. Subtract the number of existing electrons from 8 to find out how many more are needed to fill the level. For example, if there are 5 electrons in the outermost level, 3 more are needed to fill it.
The third main energy level (n=3) can contain a maximum of 18 electrons. This is because the third energy level can have 2n^2 electrons, so for n=3, this would be 2 * 3^2 = 18 electrons.
