how many electrons fit in the fourth energy level?
43437
Thus, the fourth level can hold up to 32 electrons: 2 in the s orbital, 6 in the three p orbitals, 10 in the five d orbitals, and 14 in the seven f orbitals. The sublevels of the first four principal energy levels and the maximum number of electrons that the sublevels can contain are summarized in Table 5.1.

The maximum number of electrons at a given energy level depends on its number of orbitals. There are at most two electrons per orbital. Electrons in the outermost energy level of an atom are called valence electrons. They determine many of the properties of an atom, including how reactive it is.

The valence shell of carbon (for which n=2 ) thus contains 4 electrons.

After the 4s is full we put the remaining four electrons in the 3d orbital and end with 3d4. Therefore the expected electron configuration for Chromium will be 1s22s22p63s23p44s23d9.

How many electrons in an atom may have the following quantum numbers? (a) n = 4, (b) n = 3, l = 0. b) When n= 3, l=0 means 3s orbital which can have 2 electrons .

So you want to recall about electron configurations that for d orbitals maximally you can have 10 valence electrons and for the f orbitals you can have maximally 14 valence electrons.

There are seven electrons in the highest occupied energy level of a chlorine atom. These electrons occupy the s and p sublevels, and make up the valence shell.

As an example, let's use carbon tetrachloride, CCl4. The single carbon atom contains four valence electrons, and each of the four chlorine atoms contains seven valence electrons. Therefore, the number of valence electrons for this molecule is 4 + (4 × 7) = 32.

The five d orbitals can hold up to 10 electrons. Thus, the third level holds a maximum of 18 electrons: 2 in the s orbital, 6 in the three p orbitals, and 10 in the five d orbitals. The fourth and higher levels also have an f sublevel, containing seven f orbitals, which can hold a maximum of 14 electrons.

Answer and Explanation: Fourteen electrons can be represented by the values n = 4 and l = 3.

Note you are only looking at the orbitals with the specified n value, not those at lower energies. (a) When n = 2, there are four orbitals (a single 2s orbital, and three orbitals labeled 2p). These four orbitals can contain eight electrons.

The number of electrons in a 4f subshell can be anything between 0 (if it isn't filled) and 14 (2 electrons per orbital times 7 orbitals = 14 electrons). Note that a 4f subshell can also have fewer than 14 electrons, and all f subshells (not just n=4) can hold the same maximum number of electrons.

The first energy level has 2 electrons located in the 1s-orbital and the second energy level, which in fluorine's case is the outermost energy level, has 7 electrons, 2 in the 2s-orbital and 5 in the 2p-orbitals. This means that fluorine has a total of 7 valence electrons.

The highest energy electron in Ga is the single 4p electron, which can either be in the 4px , 4py , or 4pz orbital, and it can either be spin up or spin down. So, there are 2×3=6 possible sets of quantum numbers. For the 4p orbital: n=1,2,...,N⇒4 for the principal quantum number.

In K, L,M, N shells,in the N shell it can accommodate 32 electrons. So why the outermost shell can accommodate only 8 shells?

The fourth shell has 4 subshells: the s subshell, which has 1 orbital with 2 electrons, the p subshell, which has 3 orbitals with 6 electrons, the d subshell, which has 5 orbitals with 10 electrons, and the f subshell, which has 7 orbitals with 14 electrons, for a total of 16 orbitals and 32 electrons.

A: A neon atom has two electrons in energy level I and its remaining eight electrons in energy level II, which can hold only eight electrons. This means that is outermost energy level is full.
