using the format 1s^2 2s^2 2p^6 ... (put spaces between the quanta) write the electron configuration of: si…

Explanation:

Step1: Determine atomic number of Si

Silicon (Si) has an atomic number of 14, so it has 14 electrons.

Step2: Fill electron - subshells

We fill the sub - shells according to the Aufbau principle. First, the 1s sub - shell can hold 2 electrons (1s^2). Then the 2s sub - shell holds 2 electrons (2s^2), and the 2p sub - shell can hold 6 electrons (2p^6). After that, we move to the 3s sub - shell which holds 2 electrons (3s^2), and finally, we have 2 remaining electrons in the 3p sub - shell (3p^2).

Answer:

1s^2 2s^2 2p^6 3s^2 3p^2
