D
B2Si6
Verified step by step guidance1
Step 1: Understand the naming convention for chemical compounds. The prefix 'hexa-' means 6, so 'hexaboron' indicates 6 boron atoms.
Step 2: The term 'monosilicide' means there is 1 silicon atom. The prefix 'mono-' is often omitted for the first element if it is singular, but it indicates one atom of silicon here.
Step 3: Combine the elements with their respective quantities: 6 boron atoms (B6) and 1 silicon atom (Si).
Step 4: Write the chemical formula by placing the element symbols with their subscripts indicating the number of atoms: B6Si.
Step 5: Verify that the formula matches the name: 'hexaboron monosilicide' corresponds to B6Si, confirming it is the correct formula.
