Atomic Mass is the answer
The atomic number of an element tells you how many protons an atom of that element contains. This number is unique to each element and is found on the periodic table. The number of protons in an atom determines the element's identity.
The atomic number of an element is the number of protons in the nuclei of its atoms. Each element has a unique atomic number.
same number of each element
I think it's the substance. Had this as a science Question...
it tells you what charge the element will be
The type and the number of atoms of each element present.
number of protons in the atoms tells us to what chemical element atoms belongs. in other words :different number of protons means different element. also protons together with neutrons make most of the atoms weight.
In this case, the equation is balanced.
each element has one atom of the element's name
The prefixes in a covalent compound name indicate the number of each element present in the compound. The prefixes are used to determine the subscripts in the chemical formula, specifying how many atoms of each element are bonded together.
It is important to know the relative number of atoms of each element in a compound for the chemical composition.
In this case, the equation is balanced.
