By the sum of protons and neutrons we obtain the mass number of the atom which is written at the top of the atom periodic number. We can also obtain the mass number by adding the atomic number and the number of neutrons because the atomic number and the number of protons are same. You know that scientists have discovered some particles which are smaller than protons and neutrons and these are known as quartz.
What else can I help you with?
An atoms what number is the sum of protons and neutrons?
The sum of protons and neutrons in an atom is called mass number.
What is the number on the periodic table that indicates the number of protons and neutrons in the nucleus of one atom of an element?
The number on the periodic table that indicates the number of protons and neutrons in the nucleus of an atom is the atomic mass number, which is typically located on the top of the element's symbol. It is the sum of the number of protons and neutrons in the nucleus of an atom.
In periodic table of elements it is the sum of the number of protons and neutrons of an atom.?
The sum of protons and neutrons is the atomic mass.
What indicates the total number of protons and neutrons in an atom?
The mass number of an isotope indicates the total number (the sum) of protons and netrons in an atom.The number of protons is determined by the atomic number.The number of neutrons can be found by subtracting the atomic number from the mass number.
What does the protons and neutrons tell you about the oxygen atom?
protons will tell the atomic number (8) the sum of protons and neutrons will give the mass number of the element
The mass number of an atom indicates the number of what?
The mass number is the sum of protons + neutrons.
What makes up nearly all of the atom's mass?
The sum of all Protons and Neutrons.
What term best indicates the total number of neutrons and protons in a particular isotope of an element?
The atomic mass number is the sum of the protons and neutrons of an element. The protons are given by the atomic number, so the neutrons can be found by subtracting the mass number by the atomic number. Both the mass and atomic numbers can be found on the periodic table.
What is the sum of protons neutrons in an atom?
Mass number = Protons+Neutrons

What is the mass number and what does it indicates?
The mass number of an atom is the sum of the numbers of protons and neutrons in the nucleus of the atom. It also indicates the total positive charge on the nucleus.
Is the is the sum of the numbers of protons and neutrons in an isotope of the element?
Isotopes involve different atomic masses. It is sum of number of protons and neutrons.
