What particles make up the atomic mass number of an element?
The atomic mass number of an element is determined by mass of the nucleus of an atom. Therefore the particles that make up the nucleus determine the mass number. These particles are protons and neutrons.The mass of the protons and neutrons do not vary between elements, but the number of each in the nucleus varies between elements and between isotopes of the same element.
When you subtract the atomic number from the atomic mass of any element you get what?
Atomic mass= Atomic no. + no. of neutrons So when the atomic no. is subtracted from the atomic mass, the result would be equal to the number of neutrons present in the nucleus of the atom of the element.
What two factors determines the atomic mass of a element?
The atomic mass is determined by the neutrons and the protons, found in the elements' nucleus.
The difference between the atomic number of an element and its atomic mass?
Atomic mass is the mass of an atom in atomic mass units, and includes protons, neutrons, and electrons; and atomic number is the number of protons in the nucleus of the atom.
Where is the atomic mass located?
the atomic mass is the number of neutrons plus protons/electrons in an element. it is found under the sybol on an element's card.
What is the atomic mass in an element?
The atomic mass in an element is the total number of protons and neutrons in an atom's nucleus.
What particles make up the atomic mass number of an element?
The atomic mass number of an element is determined by mass of the nucleus of an atom. Therefore the particles that make up the nucleus determine the mass number. These particles are protons and neutrons.The mass of the protons and neutrons do not vary between elements, but the number of each in the nucleus varies between elements and between isotopes of the same element.
What information could you use to determine the atomic number of an unknown element that has a mass number of 22?
the only element with a mass number of 22 is sodium (Na) which has an atomic number of 11. This is because the atomic number only represents the number of protons in the nucleus, while the mass number represents the number of protons and neutrons in the nucleus.
How is the nucleus related to the periodic table?
The nucleus contains the protons and neutrons. The number of protons determines the atomic number of the element and the number of protons and the number of neutrons together determine the atomic mass.
When you subtract the atomic number from the atomic mass of any element you get what?
Atomic mass= Atomic no. + no. of neutrons So when the atomic no. is subtracted from the atomic mass, the result would be equal to the number of neutrons present in the nucleus of the atom of the element.
Distinguish between the atomic number and mass number of an element?
The atomic number of an element is the number of protons in the nucleus of each atom of the element. Mass number is a property of a particular isotope of the element rather than of the element itself: The mass number is the sum of the numbers of protons and neutrons in the nucleus of each atom of the isotope.
How do you calculate the number of neutrons an element has in its nucleus?
You need to find the atomic number, and the atomic mass. The atomic number i the number of PROTONS in the nucleus, the atomic mass, or mass number, is the number of PROTONS and NEUTRONS in the nucleus. To find the number of neutrons you subtract the atomic number from the mass number.
What is the mass number for element A?
The mass number is the sum of neutrons and protons in an atomic nucleus.
How is the atomic number and mass number different?
The atomic number is the number of protons in the nucleus of an atom of any given element. The mass number is the number of protons and neutrons in the nucleus of an atom of an isotope of an element.
What are the atomic number and atomic mass number of?
The atomic number of an element is the number of protons in the nuclei of its atoms. Mass number is the sum of protons and neutrons in the atomic nucleus of a particular isotope of an element.
What two factors determines the atomic mass of a element?
The atomic mass is determined by the neutrons and the protons, found in the elements' nucleus.
How do you find the mass number on an element?
The mass number is the sum of protons and neutrons in the atomic nucleus.
