The following Topics and Sub-Topics are covered in this chapter and are available on MSVgo:
A chemical symbol is a one-or two-letter notation that represents an atom in a chemical element.
In the analysis of elements, a symbol is quite important. For example, the symbol Cl stands for chlorine: the chemical element. A single atom of chlorine has an atomic mass of 17 a.m.u.
The valency of an atom or radical refers to its ability to combine with other atoms or radicals. The number of hydrogen atoms that can join with or displace one atom of the element or radical is known as valency.
There are some significant features of a chemical reaction’s occurrence:-
The responding entities are written on the chemical equation’s left-hand side, whereas the compounds produced by the chemical reactions are written on the right-hand side.
It’s also worth noting that each of the symbols for the respective reactants and products has a coefficient associated with it. The precise value of stoichiometric number for each individual is represented by the coefficients of entities in a chemical equation.
In this chapter, we learned how chemistry is represented. We learned about the Chemical Reactions & Equations and their occurrence.
