by the number of atomic numbers in the element and the amount of mass numbers in the element. these are the numbers on the top and bottom of each element.eg. Helium (Symbol He) has a mass number of : 4 and an atomic number of:2
Isotopes of an element have different numbers of neutrons.
neutrons
The numbers of the elements on the periodic table correspond to the number of protons the element has. For example, Oxygen has atomic nuber 8, which means it has 8 protons.
The numbers preceding the element or compound in a chemical equation are coefficients.For example, 2Mg + 3Al means that there are two magnesium atoms (or two moles of magnesium) and three aluminum atoms (or three moles of aluminum). Most importantly, the 2 and 3 reflect the ratio of magnesium to aluminum in the equation.

True
It is the set of natural numbers.
False
A set "A" is said to be a subset of of set "B", if every element in set "A" is also an element of set "B". If "A" is a subset of "B" and the sets are not equal, "A" is said to be a proper subset of "B". For example: the set of natural numbers is a subset of itself. The set of square numbers is a subset (and also a proper subset) of the set of natural numbers.

No, the natural numbers are not closed under division. For example, 2 and 3 are natural numbers, but 2/3 is not.
I think so yah
No. Every real number is not a natural number. Real numbers are a collection of rational and irrational numbers.
Natural numbers are a special kind of Rational numbers. Rational numbers can be expressed as a fraction. (Positive) fractions with the same (nonzero) numerator and denominator are natural numbers, for example 9/9 = 1.
