In beryllium the 1s and 2s orbitals are both filled, and beginning with boron the three 2p orbitals begin filling until, with neon, the first row of the periodic table is completed. The orbital structure of the first ten elements is given in Fig. 2-7. 5. If you have the electron configuration, add up all the numerical superscripts to get the total number of electrons.

When we solve examples you should always take them in ground state. Showing Electrons in Orbitals (sub shells) We show orbitals with following shape; Capacity of each orbital is two electrons. We can also show electrons in orbitals Which element is paramagnetic using the electron configuration?

Electron configuration 1s22s22p2 Since there are three 2 p orbitals and each orbital holds two electrons, the 2p sublevel is filled after six elements. The Table

Example: H ends in 1s1 (even though H is not a metal, it resides in this group because it also has one valence electron) Li ends in 2s1 (lithium is in period 2) Na ends in 3s1 ( sodium is in period 3)

5. If you have the electron configuration, add up all the numerical superscripts to get the total number of electrons. This number will be equal to the atomic number. Look up the atomic number on the periodic table to find the element.

What period the element is in determines the 1st number.

Notice that atomic numbers 57 through 70 on the periodic table below are in the 4f portion of the table. It is a common mistake to forget that the 4f sublevel is filled after the 6s sublevel and before the 5d sublevel.

electron configuration b. principal quantum number d The 1s2 is from the first period with Hydrogen and Helium. The 2s2 is from the second period Lithium and Beryllium. Now we move onto the p-block in period 2. This means that our element will start with 2p. Since nitrogen is the third element (behind boron and carbon), we have the exponent 3 after the 2p.
