2 electrons in the first shell 8 electrons in the second shell. Like an electron in an inner shell a valence electron has the ability to absorb or release energy in the form of a photon.

A maximum of 2 electrons can fit into the first shell but 8 electrons can fit into the second shell.
. 135 pairs of electrons 5th period. Electron configurations are a bit more complicated than we make them seem. Each orbital carries 2 electrons and you can actually find that 18 electrons can be shot in.
Same as the fourth 6th period. 1 pair of electrons 2nd period. The first energy shell can take 2 electrons the second energy shell can take 8 electrons and the third energy shell can take 18 electrons.
The third shell in its lowest state has room for 8 electrons but including the higher energy 3d electrons it has a capacity of 18 electrons. The fourth energy level has 18 electronsThe fourth energy level of the periodic table includes the 4s 3d and 4p orbitals. 13 pairs of electrons 3rd period.
Same as the second 4th period. The first shell can hold up to two electrons the second shell can hold up to eight 2 6 electrons the third shell can hold up to 18 2 6 10 and so on. Of electrons in any shell 2n2 where n is the shell number.
But if it is the last shell of an element it can hold maximum of 8 electrons. How many electrons does phosphorus have in its valence shell. There is a formula for obtaining the maximum number of electrons for each shell which is given by 2n2ldots where n is the position of a certain shell.
If someone could please explain the electron correct configuration that would be really helpful. The MAXIMUM POSSIBLE no. So sodiums 11 electrons are arranged this way.
This is known as atomic excitation. The highest-numbered shell is the third shell which has 2 electrons in the 3s subshell and 3 electrons in the 3p subshell. Each shell can contain only a fixed number of electrons.
If there are 14 total electrons 10 would be found in. How many electrons are allowed in the 4th Shell. According to formula 2n2 3rd shell can hold upto 18 electrons but if it is the outer most shell then it would only have maximum 8 electrons.
When the third level contains 8 electrons the next two go into the fourth level. The 3rd shell can hold 18 electrons but it fills 8 first then the other 10 later. The third energy level can hold up to 18 electrons meaning that it is not full when it has only electrons.
One way to remember it is as follows. Why are there 18 Electrons in the Third Shell. However in the fourth shell the 19th and 20th electrons go into the 4s2 not the third shell but the next 10 electrons go into the 3d orbitals that are part of the third shell but shown on the fourth shell level.
The general formula is that the nth shell can in principle hold up to 2n2 electrons. And 1 electron the valence electron in. How many shells can an atom have.
Answer 1 of 3. Electronic configuration of Ar 18 is1s2 2s2 2p6 3s2 3p6 whereas electronic configuration of Zn 30 is 1s2 2s2 2p6 3s2 3p6 3d10 4s2. The third shell can carry up 18 electrons but it is more stable by carrying only eight electrons.
This is because it is the 3rd shells full power and it does not say the order in which the electrons are filled. In this sense the third shell can hold a total of 18 electrons. The third shell is a bit more complicated but lets just say that it takes up to 8 electrons as well for now.
A s orbital a set of 3p orbitals and a set of 5d orbitals form the 3rd subshell. An energy gain can trigger an electron to move jump to an outer shell. In this sense the third shell can hold 8 electrons.
People also ask why does the third shell have 8 electrons. That gives a total of 5 electrons so neutral phosphorus atoms have 5 valence electrons. If the third shell is not the last shell of an element it can hold maximum of 18 electrons according to 2n2 rule.
- 1st shell of an atom holds 2 electrons - 2nd shell of an atom holds 8 electrons - 3rd shell of an atom holds 18 electrons- 4th shell of an atom holds 32 electrons - 5th shell of an atom holds 50 electrons. - 3rd shell of an atom holds 8 electrons - 4th shell of an atom holds the rest of the electrons left over And for the rest of the elements of the periodic table you must have the following.
