The mass number of an atom indicates the number of what?
The mass number is the sum of protons + neutrons.
The mass number of an element is equal to the total number of?
The mass number is the average atomic mass of all the isotopes that are found in nature.
What is an element made up of?
An element is made from atoms. Atoms contain protons, neutrons and electrons. Protons and neutrons contain quarks and gluons.
What is the mass number for element A?
The mass number is the sum of neutrons and protons in an atomic nucleus.
How many protons neutrons and electrons are in k40?
K always has 19 protons, because that is what defines it as an element.40, the atomic mass is the sum of protons and neutrons. So if you subtract the number of protons from the atomic mass, you get the number of neutrons.40-19=21 neutrons
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.
The mass number of an atom indicates the number of what?
The mass number is the sum of protons + neutrons.
An atoms mass number equals the combination of what two things?
The mass number of an element is equal to the sum of the elements neutrons and protons.
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 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.
The atomic mass is equal to the sum of?
The Atomic Mass number of an element is the sum of the protons and neutrons in the nucleus of an atom of that element.The relative atomic mass is the average atomic mass number of all the known isotopes of an element.
Atoms of the same elements that differ only in the number of neutrons are known as?
Atoms of the same element that have different numbers of neutrons are called isotopes. An isotope is known by its mass number, which is the sum of the protons and neutrons in its nucleus.
How do you find the mas number of an element?
The mass number is the sum of protons and neutrons.
How do you find the mazz number of an element?
The mass number is the sum of protons and neutrons.
What is mass number made of?
The atomic mass of an element is the sum of its protons and neutrons.
What is the sum of the protons and nuetrons in an atomic number?
atomic number is the number of protons. the sum of protons and neutrons is known as mass number
The mass number of an element is equal to the total number of?
The mass number is the average atomic mass of all the isotopes that are found in nature.
