What particles make up the mass of an atom?
The number of protons
What is the total number of protons and neutron's in an atom called?
mass number = protons + nuetrons
What is the sum of the number of protons and the number nuetrons in an atom?
mass number
What is the sum number of protons and nuetrons in the nucleas of a atom?
The Mass Number.
What is the number of protons an atom has?
most of the time there are two but if you have a positively charged atom there are just more protons than electrons or neutrons MASS IS ALWAYS PROTONS PLUS NUETRONS SO IF YOU KNOW THE MASS # AND THE NUETRON # AND SUBTRACT NUETRONS FROM MASS YOU GET THE PROTON # ALSO THE PROTON # = TO THE ELECTRON # AND THE ATOMIC #
How do you determine the number of nuetrons in an atom?
Number of Neutrons = Mass number - Atomic Number
How many nuetrons are in zinc?
it has 35 nuetrons, 30 protons, and 30 electrons with a mass of 65
What is the total number protons and neutrons in an atom called?
mass number = protons + nuetrons
What is the sum of a proton and nuetrons in the nucleus of an atom?
Its the mass number of an atom.The mass of an atom is concentrated in the nucleus. Both protons and neutrons which are collectively known as nucleons are found within the nucleus.Mass of electrons are not considered to be contributing towards the mass no. of an atom as their size is small and thus their mass is negligible.
How do you find the atomic mass number of an atom of an element?
add the number of protons and nuetrons together
How are atoms different from one another?
They are different because of the number of electrons in there electron cloud. True, the number of electrons are specific to the type of atom but so are the number of protons. The atomic number of the atom is directly related to the number of protons and electrons it has. So carbon for example is given the atomic number 6. Thus it has 6 protons and 6 electrons. It's atomic mass is 12.0107 amu. This we can round to 12. To aquire the atomic mass of a given element you add the number of protons and nuetrons together since the electrons are so infinitely small they are not considered to have any mass. We know from the atomic number that carbon has 6 protons, it's atomic mass is 12, so that means the number of nuetrons must also be 6. This doesn't exactly answer the question though. The obvious things that differentiate one atom from another are their atomic number, the number of protons and electrons inside an atom, and their atomic mass.
The number of protons and nuetrons in the nucleus of an atom?
The number of protons in the nucleus determines the element's identity, while the sum of protons and neutrons gives the atom's mass number. The nucleus contains nearly all of an atom's mass and is surrounded by a cloud of electrons.
