This question is about silicon and its compounds. An atom of silicon is represented as: 1430Si^{30}_{14}\text{Si}1430Si
How many protons, neutrons, and electrons are in this atom of silicon?
The structure of a silicon compound, disilane, is shown below: 
Complete the molecular formula of this silicon compound: Si‾H‾\text{Si}_{\underline{\quad}}\text{H}_{\underline{\quad}}SiH
Silane (SiH4\text{SiH}_4SiH4) exists as small molecules and has a very low boiling point. What is the reason for the low boiling point of silane? * Covalent bonds and intermolecular forces are weak. * Only covalent bonds are weak. * Only intermolecular forces are weak.
Like diamond, elemental silicon has a giant covalent structure. How many covalent bonds does each silicon atom form in this giant covalent structure? * 1 * 2 * 3 * 4
