Electronic Configuration of First 30 Elements

What is Electronic Configuration?

In chemistry, an electron configuration is a description of the arrangement of electrons in an atom. The electron configuration of an atom determined by the number of protons in the nucleus and the number of electrons in orbitals. Therefore the electron configuration of a neutral atom is written as a list of symbols, one for each electron, and enclosed in parentheses.

Understanding the Electronic Configuration of Atoms

• The electronic configuration of atoms is the distribution of electrons among the atomic orbitals. The electronic configuration of an atom can determined by its atomic number and by the configuration of the elements in the periodic table. The electron configuration of an atom can represented by a noble gas configuration.
• However the electron configuration of an atom can determined by its atomic number and by the configuration of the elements in the periodic table. Therefore the atomic number of an atom is the number of protons in the nucleus. The configuration of the elements in the periodic table can determined by the number of electrons in the outermost energy level.
• Also the electron configuration of an atom can represented by a noble gas configuration. The noble gas configuration is the electron configuration of the elements in the eighth period of the periodic table. The noble gas configuration can represented by the symbol of the noble gas and also the number of electrons in the outermost energy level.

Table Showing the Electronic Configuration of First 30 Elements

The table shows the electronic configuration of the first 30 elements. Each element represented by a box, and the electronic configuration of the element is shown inside the box. Therefore the first column of the table shows the number of the element. The second column shows the electron configuration of the element.

Facts on Electronic Configuration

The electronic configuration of an atom is the specific arrangement of electrons in its outermost energy level. The electronic configuration of an atom can determined by its electron configuration diagram. The electron configuration diagram of an atom also called its electron dot diagram.
