What is the role of prefixes in naming covalent compounds?

• Prefixes are used to indicate the state of matter of the compound.

• Prefixes are used to specify the number of atoms of each element in the compound.

• Prefixes are used to denote the charge of the compound.

• Prefixes are used to identify the type of bond in the compound.

What is the naming convention for covalent compounds?

• Covalent compounds are named using prefixes to indicate the number of atoms of each element present in the molecule. The first element retains its name, while the second element's name is modified to end in '-ide.'

• Covalent compounds are named by using the element's atomic number and adding '-ide' to the end of the first element's name.

• Covalent compounds are named by combining the names of the elements without any modifications.

• Covalent compounds are named using Roman numerals to indicate the charge of the elements.

How do you name the compound SF₄?
