How can you find the mass from the number of atoms?
protons plus the number of neutrons.
Can an atom of two different elements have the same mass number?
Yes. The mass number is basic to the different elements, even more useful than the atomic number. (Unless it is an isotope. Isotopes have a different amount of neutrons than the basic element atom which makes a difference in mass number too. So, a difference in mass numbers doesn't always mean it is a different element.)
Where are the nuetrons found on the periodic table?
Neutrons are sub-atomic particles. The Periodic Table is an arrangement of the elements (atoms) made from these subatomic particles. Thus Neutrons by themselves have no place in the Periodic Table. However as all elements/atoms (except Hydrogen) contain some Neutrons, it is possible to find out how many using the information presented on the Periodic Table. The number of Neutrons present in an element/atom can be determined by subtracting the atomic number of an element/atom from its atomic mass.
How many neutrons are in atom of sodium?
A sodium atom typically has 12 neutrons. This is because the atomic number of sodium is 11, which represents the number of protons in the nucleus. The total mass number of sodium is around 23, so subtracting the atomic number from the mass number gives us the number of neutrons.
Is the number of protons equal to the number of neutrons in an atom?
The number of neutrons in an atom CAN be equal to the number of protons and electrons, BUT IT IS NOT ALWAYS. You can find the number of neutrons in an atom by subtracting the atomic number from the mass number. The number is often the same among the lighter elements, but the ratio of neutrons to protons quickly grows larger than one (on average) as you go further along the periodic table.
How do yo find an atoms mass number?
The mass number of an atom is determined by adding together the number of protons and neutrons in the nucleus of the atom. This information can be found on the periodic table of elements where the mass number is typically listed underneath the symbol of the element.
Do you count neutrons to find an atoms identity?
If by its identity you mean its atomic number, no. Neutrons only count towards the Atomic Mass Number, or AMU.
Where do you find neutrons?
You find the neutrons with the protons, inside the nucleus.Most neutrons are in the nucleus of atoms.
How do you find neutrons in an element?
In order to find the number of neutrons in the atoms of an element, you must specify the isotope that you are interested in. Isotopes are specified according to their mass number. For example carbon-12 is the isotope of carbon that has a mass number of 12, and carbon-14 is the isotope of carbon that has a mass number of 14. All atoms of the same element, regardless of mass number, have the same number of protons, which is the element's atomic number. To determine the number of neutrons in an isotope, you subtract the atomic number from the mass number. For example, the atomic number of carbon is 6, which means that all carbon atoms contain 6 protons in their nuclei. So, to find the number of neutrons in a carbon-12 atom, subtract 6 from 12, and you get 6 neutrons in the atoms of carbon-12. To find the number of neutrons in a carbon-14 atom, subtract 6 from 14, and you get 8 neutrons in the atoms of carbon-14.
What does the mass number?
By knowing mass number of the elements we can easily find out the number of neutrons presen in the nuclei.Physical properties of elements somewhat depends on mass number.
What is the term for atoms of the same element that differ in their mass numbers?
We can find atomic mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
How to find the number of protons atomic number and the mass number with 12 as the number of electrons and 10 as the number of neutrons?
To find the number of protons (atomic number), you can use the number of electrons, in this case 12 electrons. Since atoms are electrically neutral, the number of protons is equal to the number of electrons, which is 12. To find the mass number, you add the number of protons and neutrons together. In this case, you have 12 protons and 10 neutrons, so the mass number would be 22.
