In this video, we're going to discuss the design question.
00:04
Write the electron configuration for the following elements.
00:08
Draw atomic structure, including number of protons and neutrons.
00:12
So here, first element given here is sodium.
00:17
So for the electron configuration for this given element, sodium is here.
00:22
It has atomic number 11 and mass number 23.
00:28
So it has electronic configuration will be according to a first principle.
00:33
The it's the here the trick use here is 1 s 2 s 2p 3 s 3p 3d 4 s 4p and 4f so this is the electron configuration method for distribution of electron according to a first principle here so this is from lower to higher energy level like this.
01:23
So here we have given element is sodium having atomic number 11.
01:29
So on the basis of atomic number we can distribute electron in our sub -shell are atomic orbitals.
01:36
That here we have 1s2, 2s2, 2p6, 2p6 and 3s, 1 .1.
01:56
Number of atomic number here number of electrons number of proton is equal to number of electrons here 6 -7 8 9 10 11 so this belongs to period tree and block s and group 1 of the period table and next here is we will draw its structure like this is nucleus number of proton less number of neutron present in the nucleus and here the first shell, this is shell k, shell k contains two electrons.
02:41
And next is kl, kl.
02:47
Next is shell l contains eight electrons, eight electrons.
02:59
And last shell contains one electron here...
