Best Answer

The mass number of this atom is (10 + 11 =) 21.

Remember:

  1. Mass number is the sum of (the number of) neutrons (= 11) and protons.
  2. Atomic number is equal to the number of protons (= 10)

This atom is the least abundant isotope of neon, 2110Ne (< 0.3%)

The mass number is determined by the sum of the number of protons and neutrons in an atom. In this case, with an atomic number of 10 (which represents the number of protons), adding the 11 neutrons to it results in a mass number of 21.

What is the number of neutrons in an atom affects the atomic what?

The number of neutrons in an atom affects the atomic mass of an element. Neutrons contribute to the overall mass of the atom but do not affect its chemical properties.


Atomic mass is determined by the number of protons plus the number of?

neutrons in an atom's nucleus. It is measured in atomic mass units (amu) and provides the total mass of an atom. The atomic mass is approximately equal to the sum of the protons and neutrons in the nucleus, as the mass of electrons is negligible.


How is the number of neutrons in an atom found?

The number of neutrons in an atom can be found by subtracting the number of protons (which is the atomic number) from the mass number. The mass number is the sum of protons and neutrons in the nucleus of an atom.


How do you tell how many neutrons are in an atom with the atomic number of 12?

To find the number of neutrons in an atom with an atomic number of 12 (which is the number of protons), you would subtract the atomic number from the atomic mass number. The atomic mass number is the sum of the protons and neutrons in the atom. For an atom with an atomic number of 12, the number of neutrons can be calculated by subtracting 12 from the atomic mass number given for that specific atom.


What do you have when you subtract the atomic no from atomic mass?

Atomic number is number of protons in an atom while atomic mass is the sum of protons and neutrons in an atom when you subtract you will get the number of neutrons in an atom.


Subtracting the Atomic number from the atomic mass?

To find the number of neutrons in an atom, you would subtract the atomic number (number of protons) from the atomic mass (sum of protons and neutrons). The difference between the atomic mass and the atomic number gives you the number of neutrons in the atom.


What number is the atomic mass equal to?

The atomic mass of an element is equal to the sum of the number of protons and neutrons in its nucleus. It is not directly related to the atomic number, which represents the number of protons in an atom.


How do you find the number of neutrons from the mass number?

To find the number of neutrons from the mass number, subtract the atomic number from the mass number. The atomic number represents the number of protons in an atom, and by subtracting it from the mass number, you can determine the number of neutrons present.


The number of neutrons in the nucleus of an atom can be calculated by what?

The number of neutrons in the nucleus of an atom can be calculated by subtracting the number of protons (atomic number) from the atomic mass of the atom. Atomic mass - Atomic number = Number of neutrons.


What do you get if you subtract the atomic number from the mass number for a particular atom?

You get the number of neutrons in the atom. The mass number represents the total number of protons and neutrons in the nucleus, while the atomic number represents the number of protons. Subtracting the atomic number from the mass number gives you the number of neutrons because the difference accounts for the protons.


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.


Is atomic mass the amount of neutrons in the nucleus in the atom?

atomic mass = number of neutrons + number of protons.
