A molecular formula is a representation of a molecule that uses chemical symbols to indicate the types of atoms followed by subscripts to show the number of atoms of each type in the molecule. A subscript is used only when more than one atom of a given type is present. Molecular formulas are also used as abbreviations for the names of compounds. The structural formula for a compound gives the same information as its molecular formula the types and numbers of atoms in the molecule but also shows how the atoms are connected in the molecule. The structural formula for methane contains symbols for one C atom and four H atoms, indicating the number of atoms in the molecule Figure 1. The lines represent bonds that hold the atoms together. A chemical bond is an attraction between atoms or ions that holds them together in a molecule or a crystal.

Going back to school after summer vacation is not the easiest thing to do. In fact, it takes more mental…. How to Spend the Last Days of Summer. Dread it, run from it, the end of summer arrives all the same. And now it's here. College and University is a time in your life when you find your passions and your interests and you study….

This error means that the formula in the cell doesn't match the pattern of the formulas nearby. Doing that lets you see the formulas in all cells, instead of the calculated results. Compare the inconsistent formula with ones before and after it, and correct any unintentional inconsistencies. That will switch you back to showing the calculated results of all cells. Compare the blue arrows or ranges in blue. Then correct any problems with the inconsistent formula.

Today we double-clicked a cell, to edit the formula, but did not change anything we tested on other cells to check. When hitting enter, or clicking another cell after getting the cell in edit-mode, the cell stopped showing the formula result and instead showed the formula. I believe this has a tendency to "leak over" if adjacent cells have it.

To determine the correct subscripts in a chemical formula, you have to solve how many atoms you need to balance the charge. How do I know this?
