The '3' informs us that the element is in the 3rd Energy Level or row of the periodic table. The 'p' tells us that the element is found in the p-block which are all of the Groups to the right of the transition metals, columns The superscript '2' tells us that the element is found in the 2nd column of the p-block Group The supercripts 2, 2, 6, 2 and 2 are the number of electrons in each orbital. Simply add up these numbers, which will give you Now just look for the element on the periodic table with the atomic number of This is because the atomic number tells you the number of protons, and the number of electrons is equal to that of the protons unless the element has become an ion, of course, but since there is no information saying it is an ion, we'll assume it isn't. So, the element with the atomic number of 14 is Silicon! What element has the electron configuration 1s2 2s2 2p6 3s2 3p2? Chemistry Electron Configuration Electron Configuration. May 26, I hope this was helpful. Oct 3, Explanation: The supercripts 2, 2, 6, 2 and 2 are the number of electrons in each orbital. Related questions How do electron configurations in the same group compare?

The electron configuration of an atomic species neutral or ionic allows us to understand the shape and energy of its electrons. Many general rules are taken into consideration when assigning the "location" of the electron to its prospective energy state, however these assignments are arbitrary and it is always uncertain as to which electron is being described. Knowing the electron configuration of a species gives us a better understanding of its bonding ability , magnetism and other chemical properties. The electron configuration is the standard notation used to describe the electronic structure of an atom. Under the orbital approximation, we let each electron occupy an orbital, which can be solved by a single wavefunction. Hence, many of the rules that we use to describe the electron's address in the hydrogen atom can also be used in systems involving multiple electrons. When assigning electrons to orbitals, we must follow a set of three rules: the Aufbau Principle, the Pauli-Exclusion Principle, and Hund's Rule. Together, these four quantum numbers can be used to describe the location of an electron in Bohr's hydrogen atom.
