Here's how to determine that:

* Count the electrons: Add up the superscripts in the electron configuration (2 + 2 + 6 + 2 + 2 = 14). This tells you the element has 14 electrons.

* Atomic Number: The atomic number of an element is equal to the number of protons (and also the number of electrons in a neutral atom). Therefore, the element with 14 electrons has an atomic number of 14.

* Periodic Table: Look for the element with atomic number 14 on the periodic table. That element is Silicon (Si).
