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?

This means that every atom of potassium has 19 protons in its nucleus. In a neutral atom, the number of protons is equal to the number of electrons. So the electron configuration of potassium will involve 19 electrons. The full electron configuration of potassium is 1s22s22p63s23p64s1 .

In order to write the Potassium electron configuration we first need to know the number of electrons for the K atom (there are 19 electrons). When we write the configuration we'll put all 19 electrons in orbitals around the nucleus of the Potassium atom.

When we write the configuration we'll put all 19 electrons in orbitals around the nucleus of the Potassium atom. In writing the electron configuration for Potassium the first two electrons will go in the 1s orbital. Since 1s can only hold two electrons the next 2 electrons for Potassium go in the 2s orbital.

The electrons are arranged into shells.... And so the ion K+ must have 18 electrons: 1s22s22p63s23p6 , and this configuration is precisely the same as that possessed by argon.

So... for the element of BORON, you already know that the atomic number tells you the number of electrons. That means there are 5 electrons in an boron atom. Looking at the picture, you can see there are two electrons in shell one and three more in shell two.

The shell closest to the nucleus, 1n, can hold two electrons, while the next shell, 2n, can hold eight, and the third shell, 3n, can hold up to eighteen.

So... for the element of ALUMINUM, you already know that the atomic number tells you the number of electrons. That means there are 13 electrons in a aluminum atom. Looking at the picture, you can see there are two electrons in shell one, eight in shell two, and three in shell three.

This means that a neutral manganese atom must have 25 electrons surrounding its nucleus. Consequently, the manganese(II) cation, Mn2+ , which is formed when a neutral manganese atom loses 2 electrons, will have a total of 23 electrons surrounding its nucleus.

SImply put, two electrons of opposite spins can share one orbital (given by ml=1 ) per subshell (given by l ). Therefore, total of 8 electrons that can share those two quantum numbers.

X atom (means no radical) having 19 electrons will be sure potassium, according to the defination of atomic number. Now, the the valancy of an element is equivalent to the number of electrons present in its outermost shell.

A neutral atom of calcium, atomic number 20, contains 20 protons and 20 electrons. It has zero net charge. We calculate the number of neutrons in an atom from its mass number and atomic number: Potassium has a mass number of 39 and an atomic number of 19.

d- block elements have 1-10 electrons in the d- shell. but the (n+1)th S outer shell has either 2 or 1 electron so as to complete half filled or full filled states of the elements which have one electron less than completion of that state.
