Why is 3rd shell 8 or 18?
The third shell of an atom has 18 electrons only not 8 electrons.
You might be confused because first the electrons of 4s are filled and then the 10 electrons of 3d shells are filled.
They are filled because of the n-l rule.
So after filling the 3s and 3p subshell with 8 electrons, the next shell to fill is the 4s one..
What is the maximum number of electron in a shell?
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. The general formula is that the nth shell can in principle hold up to 2(n2) electrons.
Why are shells named KLMN?
The names of the electron shells come from a fellow named Charles G. Barkla, a spectroscopist who studied the X-rays that are emitted by atoms when they are hit with high energy electrons. … This innermost shell is now called the K-shell, after the label used for the X-ray.
How many electrons are possible in all shells with N L 4?
Therefore in n=4, number of subshells=4, orbitals=16 and number of electrons =32.
How many electrons are possible in all shells with N L value 5?
Solution : (n+1)=5 has 5s, 4p and 3d orbitals with two, six and ten electrons respectively. Therefore, the total number of electrons present is 18.
What does number of electron shells mean?
The number of electrons in the outermost shell of a particular atom determines its reactivity, or tendency to form chemical bonds with other atoms. This outermost shell is known as the valence shell, and the electrons found in it are called valence electrons.
How many orbitals are in 4s?
And the 4 sublevel has 7 orbitals, so can contain 14 electrons max.
What are the 4 quantum numbers?
Four quantum numbers can describe an electron in an atom completely:Principal quantum number (n)Azimuthal quantum number (ℓ)Magnetic quantum number (mℓ)Spin quantum number (s)
How many electrons does L 5 have?
An atom has 2 electrons in the K shell, 8 electrons in the L shell and 6 electrons in the M shell.
How many orbitals are in the 5th Shell?
25 orbitalsSo, there are 25 orbitals in 5th shell.
How many orbitals are in 5g?
nine 5g orbitalsFor any atom, there are nine 5g orbitals.

Why are there 8 electrons in the outer shell?
The eight- electrons stability of an atom is stemmed from the stability of the noble gases or the elder name inert gases, which had long been known as unreactive or noble. … However, this rule is justified for elements of second row in the periodic table, which their outermost- shell capacity is 8 electrons.
What is an electron shell diagram?
For each electron shell atom diagram, the element symbol is listed in the nucleus. The electron shells are shown, moving outward from the nucleus. The final ring or shell of electrons contains the typical number of valence electrons for an atom of that element.
