Question

complete the statement by entering a numbe a neutral si atom has valence electron(s)

Explanation:

Step1: Recall silicon's electron - configuration

Silicon (Si) has an atomic number of 14. Its electron - configuration is 1s²2s²2p⁶3s²3p².

Step2: Determine valence electrons

The valence electrons are in the outermost shell. For Si, the outermost shell is the third shell (n = 3), and it has 2 + 2=4 electrons in the 3s and 3p sub - shells.
