An atom's Atomic Mass is usually thought of as the total number of protons and neutrons together. Each has a relative mass of 1, so the count of each equals the atom's atomic mass. For example, 1 ordinary atom of sodium (Na) has 11 protons and 12 neutrons. Its atomic mass therefore is 23.
The overall atomic mass of an element, however, is a weighted average of its isotopes, which occur in consistent ratios throughout the universe.

Subtracting the Atomic number from the atomic mass?
It gives the number of neutrons in the particular atom.
What is the atomic mass of water?
The relative atomic mass of hydrogen is 1 and for oxygen it's 16. This gives water (which has the formula H2O) a molecular mass of 18.
How do you use atomis mass in a sentence?
The atomic mass gives the mass of the atom. It is one of the physical property of the atom.
If fluorine has an atomic number of 9 and an atomic mass of 19 how many electrons does fluorine contain?
The number of electrons is always the same as the atomic number. That gives you the number of protons and electrons. The atomic mass has nothing to do with it. What is the atomic number? That is your answer.
Phosphorus has an atomic mass of 31 and an atomic number of 15 the number of neutrons must be?
Mass number = no. of protons + neutrons Atomic number = no. of protonsThus (mass number - atomic number) gives you no. of neutrons.Therefore for phosphorus, the number of neutrons would be 16.
Subtracting the Atomic number from the atomic mass?
It gives the number of neutrons in the particular atom.
What is the relation of atomic mass with atomic no 6 and atomic mass 12 of carbon?
Carbon has 6 protons. With carbon-12 (the most common isotope) there are 6 protons + 6 neutrons, which gives the atomic mass of 12.
What is the atomic mass of water?
The relative atomic mass of hydrogen is 1 and for oxygen it's 16. This gives water (which has the formula H2O) a molecular mass of 18.
How do you use atomis mass in a sentence?
The atomic mass gives the mass of the atom. It is one of the physical property of the atom.
The number of protons plus the number of neutrons gives the atomic?
Mass
If fluorine has an atomic number of 9 and an atomic mass of 19 how many electrons does fluorine contain?
The number of electrons is always the same as the atomic number. That gives you the number of protons and electrons. The atomic mass has nothing to do with it. What is the atomic number? That is your answer.
If an atom has the atomic number of 4 and the atomic mass of 9.012 how many electrons will it have?
Atomic mass is protons + neutrons, and the atomic number (4) gives you the number of protons. Thus, this atom would have 5 neutrons.
How are the mass number and the atomic number of an elment different?
The atomic number denotes the number of protons in an atom where the mass number gives the sum of protons and neutrons.
What does the atomic mass give you the number of?
It gives the number of nucleons = protons + neutrons.
Relation between subatomic particles and atomic mass unit?
protons and neutrons are subatomic particles and adding the two amounts together gives you the atomic mass unit
What is the difference between mass and atomic numbers?
The atomic number gives you a hint of how many protons are in the atom. While mass is the weight of the whole atom( including protons, electrons, and neutrons).
How can you determine the number of neutrons in an atom if its mass number and its atomic number are known?
It is impossible to determine the number of neutrons from the mass number and atomic mass, since the two are essentially same value. However, with the atomic number and the mass number, one can calculate the number of neutrons by subtracting the atomic number from the mass number.
