4Na+O2= 2Na2O
The chemical formula indicates the types and quantities of atoms in a molecule or compound. Each element is represented by its symbol, with subscript numbers indicating the number of atoms present. When writing chemical equations, reactants and products are connected by plus and arrow symbols to show the transformation of atoms during a chemical reaction.
All atoms of one kind share common properties
The subscript 2 in H2O indicates that there are 2 hydrogen atoms in each water molecule. This is important for balancing chemical equations and understanding the composition of compounds.
H2SO4.
Subscripts in a compound are used to indicate the number of atoms present for each element in the compound. They show the ratio at which the elements are combined to form the compound. Each subscript number represents the number of atoms of the element that follows it.

8 seasons, plus 2 movies and a musical.
These atoms have a very similar electronegativity.
All atoms of one kind share common properties
There are 8 children, hence the TV show, Jon and Kate Plus 8.
molecule
They show how many atoms of each element are in a molecule.For instanceSF6is sulfur hexafluoride. It has one atom of sulfur and six of fluorine; the subscripted 6 shows the number of fluorine atoms.
Yes, chemical formulas show the number of atoms in a compound. Water is H2O -- two hydrogen atoms bonded to one oxygen atom. Carbon dioxide is CO2 -- one carbon and two oxygen atoms.
Oxidation Number
The electronegativities of it's two atoms are similar.
The difference between the electronegativities of the atoms is near zero.
