How do you write a covalent bond formula?

Answer 1

use the following prefixes in front of the element depending on how many atoms of the substance there are:

1.mono

2.di

3.tri

4. tetra

5. penta

6. hexa

7. hepta

8. octa

9. nona

10. deca

Also the last element with -ide

For example: P2O4 would be written as: Dipotassium Tetraoxide

Answer 2

To write a covalent bond formula, identify the elements involved and determine the number of valence electrons for each. Then, combine the elements using prefixes to indicate the number of atoms for each element. Lastly, use a subscript to indicate how many atoms of each element are bonded together.
