Write the formulas for silicon dioxide.
SiO2 so how am i suppose to write formula(s) for it? like how ?
I don't understand your confusion.
Silicon dioxide is SiO2. That's how you're supposed to write it.
To write the formula for silicon dioxide (SiO2), you need to understand the valence or oxidation numbers of the elements involved. Silicon (Si) has a valence number of +4, indicating that it can form four bonds, while oxygen (O) has a valence number of -2, indicating that it can form two bonds.
To write the formula for silicon dioxide, the total valences of silicon and oxygen should balance each other out. Since the valence of silicon is +4, and the valence of oxygen is -2, two oxygen atoms (2 x -2 = -4) are needed to balance out the +4 valence of silicon.
Therefore, for every silicon atom, you need two oxygen atoms. This relationship is represented by the formula SiO2, indicating that two oxygen atoms are bonded to one silicon atom.
So, to summarize:
- Silicon has a valence of +4.
- Oxygen has a valence of -2.
- The formula for silicon dioxide is SiO2, indicating that two oxygen atoms are bonded to one silicon atom.
