Why the 3rd main energy level can hold a maximum number of 18 electrons?

The third principal energy level has one s orbital, three p orbitals, and five d orbitals, which can each hold up to 10 electrons. This allows for a maximum of 18 electrons.

Does the third electron shell have a capacity of 8 or 18 electrons?

In this sense the third shell can hold 8 electrons. 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. So the third shell can be considered to hold 8 or 18 electrons but in total the third shell can hold 18 electrons.

Why does the third energy fit more electrons?

Why is the 3rd energy able to fit more electrons? Because 3 is a sacred number, just look at it! Q. What is the electron configuration for F?

What is AK shell electron?

Definition of K-shell : the innermost shell of electrons surrounding an atomic nucleus and constituting the lowest available energy level for the electrons — compare l-shell , m-shell.

Which energy level can hold 18 electrons?

third energy level
Note: The third energy level can actually hold up to 18 electrons, so it is not really filled when it has 8 electrons in it. But when the third level contains 8 electrons, the next 2 electrons go into the fourth level.

How many electrons are there in 3rd shell?

The second shell can hold a maximum of eight electrons. When this is filled, electrons go into the third shell, which also holds a maximum of eight electrons….Electron shells.

Energy shell	Maximum number of electrons
First	2
Second	8
Third	8

How many electrons are in the third shell of an atom?

32 electrons
The first shell (closest to the nucleus) can hold two electrons. The second shell can hold 8 electrons. The third shell can hold 32 electrons. Within the shells, electrons are further grouped into subshells of four different types, identified as s, p, d, and f in order of increasing energy.

How many electrons fit in the 3rd shell?

eight electrons
When this is filled, electrons go into the third shell, which also holds a maximum of eight electrons….Electron shells.

Energy shell	Maximum number of electrons
Third	8

Which of following energy levels can accommodate a maximum of 18 electrons?

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.
