The electron configuration is an abbreviated version of the orbital notation.
The orbital notation shows exactly where every electron is placed around the nucleus of the atom --> more specifically, what orbital and sublevel each electron is in and what the spin of the electron in an orbital is.
Remember the s sublevel only has 1 orbital and can hold 2 electrons with opposite spins.
the p sublevel has 3 orbitals each holding 2 electrons with a total of 6 electrons in the p sublevel.
the d sublevel has 5 orbitals each holding 2 electrons with a total of 10 electrons in the d sublevel.
the f sublevel has 7 orbitals each holding 2 electrons with a total of 14 electrons in the f sublevel.
n is the principal energy level (there are 7 maximum for a ground state electron)
l is the sublevel (there are 4 maximum for a ground state electron)
n l
1 1s2
2 2s2 2p6
3 3s2 3p6 3d10
4 4s2 4p6 4d10 4f14
5 5s2 5p6 5d10 5f14
6 6s2 6p6 6d10
7 7s2 7p6
Start with the first energy level, (the first row), and put a diagonal line through it then write it down: 1s2 Then go to the next energy level, (n = 2), and put a line through the 2s and write it down next to the 1s2: 1s2 2s2. Then finish the 2nd row by putting a line through the 2p and the 3s which is diagonally underneath it and write those down next to the 1s2 2s2: 1s2 2s2 2p6 3s2. Continue doing this until you have the entire electron configuration.
The order of electron configurations is:
1s2 2s2 2p6 3s2 3p6 4s2 3d104p6 5s2 4d10 5p6 6s2 4f14 5d10 6p6 7s2 5f14 6d10 7p6
The orbital diagrams have the same order but you will see each orbital in the s, p, d, and f sublevels:
This is for Al, Si, P, and S.
Notice that you still draw every orbital in a sublevel (look at 3p in Al), even if you don't fill up that sublevel.
Also, notice Si: It has 2 electrons in the 3p. You don't pair them up in an orbital because there are only 2. You don't start pairing them up until you have 4, 5, or 6 electrons in the p sublevel.

What is the electron configuration of an element?
The electron configuration of an element shows the number of electrons in their energy levels and orbitals. For example, the electron configuration of a neutral magnesium atom, Mg, with 12 electrons, is 1s22s22p63s2. This means that there are two electrons in the s orbital of the first energy level, two electrons in the s orbital and six electrons in the p orbital of the second energy level, and two electrons in the s orbital of the third energy level. The number in front of each letter represents the energy level, the letter represents the orbital, and the superscripts represent the number of electrons in the orbital.

The first period in the peroidical table represents elements that possese elements only the first energy level is orbital thefore this perid contains?
two elements, hydrogen and helium.
Why is there no p block elements in the first period of the periodic table?
The first period of the periodic table can hold a maximum of 2 electrons, which are filled in the s orbital. There are no p orbitals in the first period, which is why there are no p-block elements in the first period. The p-orbital becomes available in the second period.

How the first twenty elements were discovered?
The discovery of the first twenty elements was a result of experiments by various scientists over time. Elements like hydrogen and oxygen were known since ancient times, while others, like phosphorus and sulfur, were isolated from minerals in the 17th and 18th centuries. The discovery of new elements accelerated in the 19th century with advancements in analytical chemistry, leading to the isolation and identification of elements like sodium, potassium, calcium, and others.
