For a given atomic number. Then that neutrally charged element has the same number of protons and electrons.
e.g. Carbon ; Atomic Number 6, has 6 protons and 6 electrons.
For a given Atomic Mass , the the number of neutrons can be found, by subtracting the mass from the atomic no.
e.g. Carbon ; Atomic Mass 12, has 12 - 6 = 6 neutrons.
Most elements can exhibit different atomic masses , known as ISOTOPES. , This is when the given element has a different number of neutrons.
e.g. Carbon ; atomic mass 13 , has 13 - 6 = 7 neutrons , described as Carbon -13 or C-13
Similarly Carbon again ; atomic mass 14, has 14 - 6 = 8 neutrons, described as Carbon-14 or C-14.
A further example is hydrogen. It exhibits three isotopes.
protium ; 1 proton, 0 neutrons and 1 electron Mass = 1 (H-1 or H)
deuterium ; 1 proton, 1 neutron and 1 electron Mass = 2 (H-2 or D)
tritium ; 1 proton 2 neutrons and 1 electrons. Mass = 3 (H-3 or T)
Notice in all three isotopes the number of protons remains the same, so it is still the same element.

∙ 13y agothe number of protons and electrons is equal. if there are 3 protons there are 3 electrons and the atomic mass is protons plus neutrons so to find them
atomic mass - atomic number= number of neutrons

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.
What is the number of protons electrons and neutrons in n-14?
Nitrogen-14: 7 Protons, 7 Electrons, 7 Neutrons To work this out in the future for other elements: Protons = Atomic Number Electrons = Atomic Number Neutrons = Atomic Mass - Atomic Number Hope this helps!
How do you determine the number of protons electrons and neutrons present in an element by identifying its atomic and mass numbers from the periodic table?
Atomic number means number of protons present in an atom. Atomic number= number of protons. mass number = number of neutrons+ number of protons. So if you subtract the number of protons you get neutrons and if you subtract neutrons you get protons. mass number - protons= neutrons Mass number - neutrons = protons.
How many protons neutrons and electrons does si-28 have?
Silicon 28 (28Si) has 14 protons, neutrons and electrons.
How do you calculate the number of protons neutrons and electrons of an atom?
The charge of an ion can be calculated by adding up the protons and subtracting the electrons. When oxygen with 8 protons has 8 electrons it is neutral, when it has 7 electrons it is positively charged.
What is the number neutrons for samarium?
Because the atomic number is 62, the element Samarium has 62 electrons and 62 protons. Since the number of neutrons is calculated by subtracting the atomic number from the atomic mass, and Samarium's atomic mass is 150, it has 88 neutrons.
What are the number of protons neutrons and electrons in an element?
Number of protons = Number of electrons = Atomic number Number of neutrons = Atomic number - Number of protons
Atomic particles located in the nucleus?
Neutrons and protons.
How many protons and neutrons in the fluorine?
Fluorine has an atomic number of 9. Therefore it has 9 protons and electrons. It has an atomic mass of 19 amu. Therefore, the number of neutrons present can be calculated by subtracting the number of protons from its mass, i.e., 19-9=10. thus, fluorine has 9 protons and 10 electrons.
How many protons neutrons and electrons are found in phosphorous?
Phosphorus has an atomic no. of 15 and its atomic mass is 31.=we know,atomic no.=number of protons==also, atomic mass=no.of protons+no. of neutrons==this implies, 31=15+no. of neutrons= 31-15=no. of neutrons= 16=no. of neutrons==also,no. of protons=no, of electrons=so, total no. of protons=15total no. of electrons=15total no. of neutrons=16
What is the number of protons in the necleus?
# of protons = # of electrons # of protons/ electrons + # of neutrons = 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 many protons neutrons electrons atomic number and atomic mass does bromine have?
Protons - 35 Neutrons - 43 Atomic Number - 35 Electrons - 35
How are protons and neutrons related?
For a stable atom, no. of protons= no. of electrons no of neutrons= Atomic Mass- no. of protons
Where are protons neutrons and electrons located?
Protons, neutrons and electrons are located in the atom. The protons and neutrons are located in the atomic nucleus; the electrons are around the nucleus, arranged in shells.
What is the number of protons electrons and neutrons in n-14?
Nitrogen-14: 7 Protons, 7 Electrons, 7 Neutrons To work this out in the future for other elements: Protons = Atomic Number Electrons = Atomic Number Neutrons = Atomic Mass - Atomic Number Hope this helps!
