In a chemistry class, Josue and Michael are learning about covalent compounds. They discover that covalent compounds are named by adding _______ to the element names.

• prefixes

• suffixes

• numbers

• symbols

Answer explanation

Covalent compounds are named using prefixes to indicate the number of atoms of each element present. For example, 'di-' for two and 'tri-' for three. Thus, the correct answer is 'prefixes'.

Yamilet and Treasure are learning about covalent compounds in their chemistry class. They discovered that the names of covalent compounds contain _______ that indicate the number of atoms that are present in each element in the covalent compound.

• prefixes

• suffixes

• symbols

• numbers

Answer explanation

The names of covalent compounds use prefixes to indicate the number of atoms of each element. For example, 'di-' means two, 'tri-' means three, etc. This is why 'prefixes' is the correct answer.

When Tony and Gustavo are writing covalent compounds for their chemistry project, they find that the _______ are determined directly from the prefixes in the name.

• subscripts

• coefficients

• charges

• masses

Answer explanation

In covalent compounds, the prefixes in the name indicate the number of atoms of each element. These numbers are represented as subscripts in the chemical formula, making 'subscripts' the correct choice.
