These are the steps you should use for balancing equations.:
1)Take the unbalanced equation and make a note of the elements present in each side of the equation.
2)Now, count the number of molecules of each element present on both sides of the equation.
3)Here comes the task of balancing the chemical equations. You should see that same numbers of molecules of all elements are present on the reactants side as well as the products side. The equation should follow law of conservation of mass i.e. matter is neither created nor destroyed.
4)While balancing the equations you should only change the co-efficient of the chemical formula but not the subscripts. Changing the subscripts will change the components.
Start by balancing one element at a time. 5)Finally check if all the elements are balanced. By ( Motaz Ahmed)

Valence electrons – electrons on the outer / last shell
Ground state – not excited, all electrons are in their normal Bohr orbit spots.
Atomic #83 and above are unstable and radioactive
Compounds with a transition metal produce color
Elements found only in a compound in nature are highly reactive elements.
• Nonmetals toward the top of the periodic table tend to be gases and become liquid and solid at STP as we go down a group/ family / column.
