The mass number for an atom of an element when stated with the element's symbol indicates that you have an?
You think probable to an isotope.
An atom has an atomic number of 56 yet has a mass number of 137 amu evalution of data indicates that the element is?
barium
What number represents the mass number?
The mass number indicates the sum of the number of protons and neutrons of the isotope. The mass number, nucleon number or atomic mass indicated about the respective chemical symbols in the periodic table are average figures based on the different isotopes and their relative abundance. That is why there are decimals in mass numbers in the periodic table. It can be used to compare the relative atomic masses of different atoms.
The mass number of an atom indicates the number of what?
The mass number is the sum of protons + neutrons.
What does the number below each symbol represent?
The average Atomic Mass
What does the number beneath carbon indicates?
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 is a number in parenthesis on a periodic table?
The number in parenthesis indicates the atomic mass of the most stable isotope of the element.
The sum of the protons and the neutrons indicates the .?
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.
Why atomic mass is always greater than atomic number?
Atomic number indicates the number of protons in the nucleus of a given element, whereas atomic mass results from protons and neutrons.

What is the N in 2N h2so4?
N stands for molality and it indicates the number of moles of a substance in a unit mass of the solution.
Why does the atomic number of an atom differ from the atomic mass?
Because the atomic number indicates the number of protons per nucleus while the mass number is the sum of the number of protons and the number of neutrons per nucleus, and all atoms except hydrogen-1 have neutrons in their nuclei.
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.
The mass number of an atom indicates the number of what?
The mass number is the sum of protons + neutrons.
