How can the number of protons electrons and neutrons be calculated when giving the mass number?
The atomic number must be known along with the mass number. Then the number of protons or electrons is the same as the atomic number, and the number of neutrons is the difference between the mass number and the atomic number.
The number of neutrons in the nucleus of an atom can be calculated by what?
Subtracting the atomic number from the isotope mass number.
How do you calculate how many neutrons there are in an atom?
The number of neutrons in an atom is easily calculated by taking the mass number and subtracting the atomic number. Take for example, Uranium: the mass number on the periodic table is 238, while the atomic number is 92. Take the difference of 238 and 92 and that will be equal to the number of neutrons. 238-92=146
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.
How do you determine electron density given atomic density?
The electron density is simply deduced from the atomic density as follows : if ne denotes the electron density and na the atomic density then : ne= z na with z being the number of valence electron per atom.
How Mendeleev calculated atomic number in 17 th century?
Mendeleev calculated atomic number by increasing atomic number, which match the number of protons in an atomic nucleus of a single element
What does the formula atomic mass minus the atomic number equal?
By subtracting the mass number and the atomic number, the number of neutrons can be calculated.
How is the number of neutrons in an atom found?
The number of neutrons can be calculated if the atomic number and mass number of an element is known. The number of neutrons = Mass number - atomic number.
How do you calculated electrons?
electron equals the atomic number
Can the number of neutrons in the nucleus be calculated by subtracting the atomic number from the mass number?
Yes.
How is the atomic mass calculated for neon?
Neon is a non meta element. Atomic mass of it is 20. Atomic number of it is 10.
Neutrons in the nucleus of an atom calculated?
Mass number minus atomic number = number of neutrons
What is equal to the total number of protons and neutrons?
If you add the number of protons to the number of neutrons in an atom, you have calculated that atom's atomic mass.
Protons are the same as the mass or the atomic?
The atomic number is the number of protons. For example, the atomic number of Hydrogen is 1, because it has 1 proton. The mass is calculated using protons, neutrons, and electrons.
How can the number of protons electrons and neutrons be calculated when giving the mass number?
The atomic number must be known along with the mass number. Then the number of protons or electrons is the same as the atomic number, and the number of neutrons is the difference between the mass number and the atomic number.
How do you calculate nutrons?
neutron can be calculated by subtracting the atomic number of the particular atom from its mass number.
How is atomic mass mass number and atomic number calculated?
Allthese can NOT be calculated being physical properties of each specific element. They can be found in 'periodic tables' eg. by typing in the element name in a wikipedia-search
