How do you calculate how many protons neutrons and electrons are in an atom?

The number of protons is given to you-- it's the atomic number. The number of electrons always equals the number of protons. To calculate the number of neutrons, subtract the number of protons from the atomic mass number given.


Calculate the number of protons of the atom whose mass number is 19 and whose number of neutrons is 10?

Mass number 19 means a total of 19 protons and neutrons. If it has 10 neutrons, that leaves 9 protons, which is Fluorine.


How do you calculate protons and neutrons?

Protons = element numberNeutrons = mass number of isotope - element number


How do you calculate the atomic mas based on the number of protons and neutrons of an atom?

Atomic mass is simply the sum of the number of protons and the number of neutrons. If an atom has "A" protons and "B" neutrons, its atomic mass is A + B.


How do you calculate the number of protons neutrons and electrons of an atom?

In the neutral atom the number of electrons and protons is equal to the atomic number.The number of neutrons is mass number-number of protons.


How can you calculate the number of neutrons in the atom?

To calculate the number of neutrons in an atom, subtract the atomic number from the atomic weight. That will give you the number of neutrons. The atomic number is the number of protons. The atomic weight consists of the number of protons plus the number of neutrons. (The electrons add very little to the atomic weight.)


How can you calculate the number of neutrons in atoms?

equal to number of protons


How can one calculate the number of neutrons in the nucleus of an atom?

Simply take the atomic mass (number of protons and neutrons) and subtract the atomic number. (number of protons)


How you calculate the the number of neutrons in an atom?

The number of neutrons is the difference between mass number and the number of protons.


Calculate the number of protons electrons and neutrons in helium-6?

Helium-6 has two protons and electrons and four neutrons.


The mass number is used to calculate the number of what?

The number of protons and neutrons in the nucleus


What equation tells you the how to calculate the number of neutrons in an atom?

This equation is:Mass number - number of protons = number of neutronsMass number is the sum of protons and neutrons and has a value near the atomic mass of an isotope.


How do you get the number of neutrons?

The isotope number and the atomic number can be used to calculate the number of neutrons. Consider carbon-14. The atomic number for carbon is 6 (i.e., the number of protons is 6). The isotope number of carbon-14 (i.e., 14 = protons + neutrons). Subtract the atomic number from the isotope number calculate the number of neutrons (8 for carbon-14).


How do you calculate the number of protons neutrons and electrons in a neutral atom?

The number of electrons in an atom is always equal to the number of protons in that same atom. Since the atomic mass of a periodic element equals the weight of the atoms protons AND its neutrons, the following equation can be used to calculate the number of any given particle in an atom: number of neutrons = atomic mass - atomic number


How do you calculate mass number?

Add the number of protons and neutrons, to get atomic mass number.


What must you add to calculate the mass number of an element?

The number of protons and the number of neutrons.


How do you calculate how many neutrons there are in a atom?

The atomic weight minus the number of protons = the atom's neutrons.


How do you calculate how many neutrons are in a element?

You have to know the mass number of the isotope. The number of neutrons is the mass number minus the atomic number (no. of protons).


Mass number used to calculate the number of?

the mass number of an atom is used to calculate the number of neutrons and protons in the nucleus of an atom


How do you calculalte the number of neutrons in an atom?

One doesn't generally "calculate" the number of neutrons. The number of neutrons in an atom is always equal to the number of protons, and the number of protons can be found on the Periodic Table of Elements, which can easily be found on the internet or in a science textbook.


How can you calculate the number of proton in an atom?

A^E_Z , Z = number of protons A = number of nucleons ( number of protons + number of neutrons) a. f. i. 12^C_6


How do you calculate the overall charge of an atom?

Add the number of protons and neutrons.


How do you calculate the number of neutrons in the nucleus?

You subtratct the number of protons (atomic number) from the atomic mass


How do you calculate the atomic number of the given element?

protons plus neutrons = atomic number


What equation tell you how to calculate the number of neutrons in an atom?

The number of neutrons is the difference between the mass number (n+p) and the number of protons.
