Why is atomic mass for an element an average on the periodic table?

The Atomic Mass is an average because most atoms have isotopes sometimes up to 10 or more. These all have different numbers of neutrons and subsiquently different weights. For this reason an average of these weights needs to be used for the atomic mass.

What is the difference between average atomic mass and atomic mass?
What element on the periodic table weighs 19.32?
No element has an atomic weight of 19.32 on the periodic table.
What is the average atomic mass for cobalt?
Cobalt is a meta element. Atomic mass of it is 59.
Can you find the atomic number of an element on the periodic table?
Atomic number of an element can be found on the periodic table. It is located at the upper left-hand corner of the table.
What element is the first on the periodic table?
Hydrogen is the first element on periodic table. Its atomic number is 1.
What is the weighted average of the atomic masses of an element's naturally occurring isotopes is called the?
The atomic weight that is listed on the periodic table for each element is the weighted average of the atomic masses of an element's naturally occurring isotopes. So you are describing atomic weight as it is used on the periodic table.
What does the periodic table contain?
The four pieces of information in each box of most periodic tables are the element's name, the element's symbol, the element's average atomic weight and the element's atomic number. Other periodic tables have other information, but standard periodic tables almost always have those four.
What is the difference between average atomic mass and atomic mass?
What is the atomic number on the periodic table?
The atomic number on the periodic table is the number of protons for the element.
An average of the masses of all the naturallly occurring isotopes of an element?
The weighted average for all isotopes that occur in nature for an element is its atomic weight listed on the Periodic Table of the elements.
What element on the periodic table weighs 19.32?
No element has an atomic weight of 19.32 on the periodic table.
What is the weighed-average mass of all the known isotopes for an element called?
Average Atomic Mass, or Atomic Weight of an element (the one shown on the Periodic table).
What is the average atomic mass for cobalt?
Cobalt is a meta element. Atomic mass of it is 59.
Can you find the atomic number of an element on the periodic table?
Atomic number of an element can be found on the periodic table. It is located at the upper left-hand corner of the table.
Is the atomic number of each element included in the periodic table?
YES!!! The atomic No. is the postition of the element in the periodic table. It also indicates the number of protons in the element and electrons in the neutral element. The Atomic Mass is also included in the periodic table. The Atomic Mass is the sum of all the protons and neutrons of an element in the periodic table. Here are some examples. Hydrogen ; [1/1]H The first element in the table Carbon ; [12/6]C The sixth element in the periodic table Oxygen ; [16/8]O The eighth element in the periodic table et.seq., The first number given is the Atomic Mass and the second number is the Atomic Number.
What element is the first on the periodic table?
Hydrogen is the first element on periodic table. Its atomic number is 1.
What is the isotope number used for on the periodic table?
There is not an isotope number on the Periodic Table of Elements. There is an atomic number (# of protons) and the average atomic mass. The average atomic mass is the weighted average of all the naturally occurring isotopes for each element. This number is not a whole number, because it is an average of all the isotopes for a particular element.
