Proton + Nuetron = Atomic Mass
What else can I help you with?
How do you determine neutrons in an atom of sodium-20?
the atomic mass
How do you determine the numbers of the three types of particles in each atom?
In an atom, no. of protons = no. of electrons=atomic no. no. of neutrons=atomic mass-atomic no.
Which of the following particles is used to determine the mass of an atom?
Mass of an atom is determined by the no. of protons+ no. of neutrons in the atom.
How you can determine the number of protons electrons and neutrons an atom has from an atom's mass number and its atomic number?
To determine the number of protons, look at the atomic number. The number of electrons is also the atomic number.To find the number of neutrons subtract the atomic number from the Atomic Mass number.
How do scientists determine the number of neutrons and isotopes in an atom?
Atomic mass minus atomic number. This is rather simplified but the atomic mass of an element is the total of all the protons, neutrons, and electrons in an atom. Each proton and neutron has an atomic mass of approximately 1 AMU (atomic mass units) while an electron has an atomic mass of about 0.0005 AMU. So, you don't need to worry about the electrons. The atomic number of an element is simply the number of protons in the atom. So, atomic mass (number of protons and neutrons) minus atomic number (number of protons) equals number of neutrons in an atom.
To determine the number of neutrons in an atom, what must be done?
To determine the number of neutrons in an atom, subtract the atomic number (number of protons) from the atomic mass number (rounded mass of the atom). Neutrons are particles found in the nucleus of an atom and carry no charge.
What is an atomic mass number?
Atomic mass and atomic number are two different things. Atomic mass is the mass of an atom compared to that of hydrogen. The atomic number is the atom's position in the periodic table. It's also the number of protons it has.
What are counted in an an atom to determine mass number?
Atomic Mass: protons AND neutrons atomic number: just protons
How do you determine the atomic mass number of any atom?
protons plus neutrons
What does one determine an atoms atomic mass?
If you mean "how does one determine an atoms atomic mass?", then the answer would be to find a periodic table of elements where the whole numbers indicate atomic number and the other indicating atomic mass. Atomic number is generally described as the number of protons in a naturally occurring atom of a given element, and the atomic mass is the number of protons + number of neutrons in an atom.
Does an atom of aluminum and an atom of gallium have the same atomic mass?
No, an atom of aluminum and an atom of gallium do not have the same atomic mass. Aluminum has an atomic mass of approximately 26.98 atomic mass units, while gallium has an atomic mass of approximately 69.72 atomic mass units.
How do you determine the number of nuetrons in an atom?
Number of Neutrons = Mass number - Atomic Number
