How many electrons can the nth shell hold?
The general formula is that the nth shell can in principle hold up to 2 (n2) electrons. How many electrons can the 4th Shell hold? Why is 3rd shell 8 or 18?
How many electrons can go in the first shell?
The first shell (of all atoms) has 1 subshell of s-orbitals containing 1 s orbital. This means that the first shell can hold 2 electrons. The second shell has 2 subshells: 1 s-orbital and 3 p-orbitals.
First, we look at the n=1 shell (the first shell). It has: The 1s orbital An s-orbital holds 2 electrons. Thus n=1 shell can hold two electrons. The n=2 (second)shell has: The 2s orbital The 2p orbitals s-orbitals can hold 2 electrons, the p-orbitals can hold 6 electrons.
Thus n=1 shell can hold two electrons. The n=2 (second)shell has: The 2s orbital The 2p orbitals s-orbitals can hold 2 electrons, the p-orbitals can hold 6 electrons.
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.
Another thing we wanted the answer to was, how many electrons can be in each shell of an atom?
Each shell can contain only a fixed number of electrons: 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.
Because the first shell can only hold a maximum of 2 electrons, the third electron must go into the second shell. … The 2s subshell holds a maximum of 2 electrons, and the 2p subshell holds a maximum of 6 electrons. This means that the second shell can hold a maximum of eight electrons (2+6=8).
Why can the first shell only hold 2 electrons?
This first shell has only one subshell (labeled 1s) and can hold a maximum of 2 electrons. This is why there are two elements in the first row of the periodic table (H & He). Because the first shell can only hold a maximum of 2 electrons, the third electron must go into the second shell.
Moreover, why are there only two electrons in the 1s shell?
Let us figure it out. there are only two electrons in the first atomic shell, the 1s shell, for a rather odd reason. It’s because linear momentum is a bit more fundamental, and more specifically a bit more symmetric, than angular momentum.
How many electrons can an orbital hold?
As an orbital can contain a maximum of only two electrons, the two electrons must have opposing spins. What has 2 electrons in the first shell? How many electrons can the first and second shell hold?
