State symbols are used to show the physical state of reactants and products in a reaction, at the reaction temperature. This means the temperature at which the reaction takes place. State symbols are shown in subscript, just like when we use numbers to show how many atoms are in a molecule such as diatomic oxygen (O₂).

Nov 21, 2017 · So its state symbol will be $\text{(aq)}$. Hydrogen on the other hand is a gas (at room temperature and above) and highly insoluble in water: it will leave the reaction as gas and its state symbol will be $\text{(g)}$. So without knowing the physical/chemical properties of the reagents/reaction products, the state symbols cannot be determined.
Solid, Liquid, Gas & Aqueous. State symbols are written after each formula in chemical equations to show which physical state each substance is in. Brackets are used and they are not usually subscripted although you may come across them written in this way.

A fully detailed chemical equation will show the state (or phase) of matter that the atoms or molecules are in. These states are: Solid, given the symbol (s) Liquid, given the symbol (l) Gas, given the symbol (g) Aqueous, meaning dissolved in water, and given the symbol (aq)
Its Lewis symbol would therefore be: Fluorine, for example, with the electron configuration [He]2s 2 2p 5, has seven valence electrons, so its Lewis dot symbol is constructed as follows: Figure 8.1.2. Lewis used the unpaired dots to predict the number of bonds that an element will form in a compound. Consider the symbol for nitrogen in Figure 8 ...
