How is the atomic mass of an element used to determine the number of nuetrons in its atom?
Different isotopes of the same element have different numbers of neutrons but the same number of protons. The sum of the protons and neutrons is called the mass number. If you know the mass number and the number of protons (which is the atomic number), then you simply subtract the protons (or atomic number) from the mass number and the result is the number of neutrons.
Example:
Carbon-14 has a mass number of 14. Carbon's atomic number (and number of protons) is 6. So, 14 - 6 = 8 neutrons.
What else can I help you with?
How do you calculate the amount of protons or neutrons in an element?
well you look at the periodic table of elements. the atomic number equals the number of protons. Then subtract the number of protons from the atomic mass (both protons and nuetrons have atomic mass units of 1 and electrons equal 0). That will give you the number of nuetrons.
Which particle determines the atomic number of an element?
The atomic number of an element is determined by the number of protons.
Which mass number or atomic number determine what element an atom is?
The identity of the element is determined solely by the atomic number, which is the number of protons.
What is atomic number same as?
The atomic number is the same as the number of protons.
How many nuetrons does an einsteinium element have?
99 protons 99 electrons Number of neutrons = Atomic mass of an isotope - Atomic number of the element Einsteinium's atomic number is 99 but Es has 19 known isotopes.Einsteinium has 99 protons.
How do you determine the number of nuetrons in an atom?
Number of Neutrons = Mass number - Atomic Number
How do you find the atomic mass number of an atom of an element?
add the number of protons and nuetrons together
Which element has thea mass number of 23 and12 nuetrons?
Sodium is a metal element. Atomic mass number of it is 23.
How do you calculate the amount of protons or neutrons in an element?
well you look at the periodic table of elements. the atomic number equals the number of protons. Then subtract the number of protons from the atomic mass (both protons and nuetrons have atomic mass units of 1 and electrons equal 0). That will give you the number of nuetrons.
Which particle determines the atomic number of an element?
The atomic number of an element is determined by the number of protons.
What is the relationship between mass number and atomic numbers?
The mass number is the sum of protons and neutrons in an atom's nucleus, while the atomic number is the number of protons in the nucleus. The atomic number uniquely identifies an element, while the mass number helps determine the atom's mass.
How does a neutral atom change when its number of protons electrons or nuetrons change?
The element becomes a new element becuase the atomic number would change. For example if you added a proton to Hydrogen-atomic number 1, it would become helium-atomic number 2
Which mass number or atomic number determine what element an atom is?
The identity of the element is determined solely by the atomic number, which is the number of protons.
What is the atomic mass for the element carbon is 12.011?
the atomic mass of just pure carbon would be twelve. the atomic mass is only effected by the number of protons and numbers of nuetrons
How many nuetrons does the element sulfur have?
I don't have a periodic table, but round its atomic mass to a whole number and subtract the amount of protons which equal the atomic number. So if the atomic mass is 24 and the atomic number is 12, 24-12=12.- example
If the atomic number of element D is 20 then what is the atomic number of element R?
34
How can you determine the number of electrons in an element?
To determine the number of electrons in an element, you can look at the atomic number of the element on the periodic table. The atomic number represents the number of protons in the nucleus of an atom, which is equal to the number of electrons in a neutral atom.
