atomic mass is the sum of a number of neutrons and protons that are present in a particular nucleus of an element. while the atomic number is the number of protons present in an atom. the basic Difference Between Atomic Mass And Atomic Number is that atomic mass is the average weight of an element and it is always a smaller value than the mass number. on the other hand, atomic number is the total number of protons in the atom’s nucleus. isotopes have different mass numbers. the atomic number helps in the classification of an element.
Difference Between Atomic Mass And Atomic Number in tabular Form
|Atomic Mass||Atomic Number|
|the number of protons and neutrons present in the nucleus of an element represents the atomic mass of such an element.||the number of protons only present in the nucleus of an element represents the atomic number of such an element.|
|known as the average weight of the element.||gives the idea of the total number of protons in the atom’s nucleus.|
|It is denoted by A.||It is denoted by the capital letter Z.|
|it does not give evidence of the type of element.||it does not give evidence of the type of element but only helps to classify and identify an element.|
|differentiate the type of isotopes present in the same element.||only those isotopes are share that possesses the same atomic number.|
|we use the atomic mass unit (AMU) as a standard unit to measure the atomic mass||it is a digital value that can be placed in the periodic table to represent the particular element.|
|the isobars have the same atomic mass.||the isobars have different atomic numbers.|
|always have a greater value than atomic number.||always have a smaller value than atomic mass.|
|impacted by the number of neutrons.||do not impact by the number of neutrons.|
The atomic mass of an element is the sum of a number of neutrons and protons that are present in a particular nucleus and is also known as the atomic weight of an element. It is the weighted average mass of an atom of an element based on the relative natural abundance of that element’s isotopes. It is a decimal number.
In fact, the number of protons indicates that what atom we are looking at, for example, all atoms with 6 protons are carbon atoms. For example, Hydrogen has three natural isotopes: 1H, 2H, and 3H. Each isotope has a different mass number. It is denoted by A.
We use the atomic mass unit (AMU) as a standard unit to measure the atomic mass. It always has a greater value than the atomic number. The oxygen atom contains 8 electrons and protons.
The atomic number is the number of protons only present in the nucleus of an element represents the atomic number of such an element. Every element on the periodic table has its own atomic numbers. You can distinguish one element from another by this number.
The atomic number is simply the number of protons in an atom. The atomic number is also known as the proton number. it is denoted by the letter Z. Atomic numbers are always whole numbers because protons are units of matter. The atomic number of an element is so important because you identify the elements of an atom. In the modern periodic table, the elements are organized according to increasing atomic numbers.
It is a key factor in determining the properties of an element. Note that the number of valence electrons determines chemical bonding behavior. A carbon atom contains 6 protons and its atomic number is 6.
