Tetraiodosilane is the chemistry name for Sil4.
Silicon is a non-metal, a metalloid. It would be expected to form covalent bonds. This is born out in practise, no compounds contain Si4+, no compounds contain Si4-, There are some cluster anions of silicon e.g. Si44- in NaSi, Na4Si4
In Cantonese, "bedtime" is said as "訓覺時間" (fan3 gaau3 si4 gaan3). The term "訓覺" (fan3 gaau3) means "to sleep," and "時間" (si4 gaan3) means "time." Together, they convey the idea of the time for sleeping.

A silicon atom can become a Si4+ ion by losing four valence electrons, resulting in a positive charge of 4+. This occurs when the silicon atom forms ionic bonds with other atoms by donating its electrons to achieve a stable electronic configuration, typically found in compounds such as silicon tetrachloride (SiCl4).
In Mandarin Chinese, 48 is pronounced si4 shi2 ba1. And, in Cantonese Chinese, 48 is pronounced si3 sap6 batt3.
Tetraiodosilane is the molecular compound name for Sil4.
