the 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
In a neutral atom of 243Am (Americium), there are 95 protons (which corresponds to its atomic number), approximately 148 neutrons (which can be calculated by subtracting the atomic number from the atomic mass), and 95 electrons (equal to the number of protons in a neutral atom).
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.
Potassium-43 has 19 protons, 24 neutrons, and 19 electrons. The number of protons and electrons is determined by the element's atomic number (which is 19 for potassium), while the number of neutrons is calculated by subtracting the atomic number from the isotope mass number.
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.
The number of protons in the nucleus of an atom determine its atomic number, while the number of neutrons and electrons can vary based on the specific isotope. In a neutral atom, the number of electrons is equal to the number of protons. The number of neutrons can be calculated by subtracting the atomic number from the atomic mass.

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.
Number of protons = Number of electrons = Atomic number Number of neutrons = Atomic number - Number of protons
The atomic mass of the element with eight protons and nine neutrons is 17 atomic mass units. This is calculated by adding the number of protons and neutrons together, as electrons contribute negligible mass to the overall atomic mass.
Neutrons and protons.
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
# of protons = # of electrons # of protons/ electrons + # of neutrons = atomic mass
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.

In a neutral atom, the number of electrons is equal to the number of protons. The number of neutrons can be calculated by subtracting the atomic number from the atomic mass.
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.
