Which of these makes up an atom's mass number?
The mass number of an atom is determined by the total number of protons and neutrons in the nucleus of the atom. It does not take into account the number of electrons, which are negligible in terms of contributing to the mass of an atom.
Why we sum protons and neutrons for the atomic mass why we don't take neutrons?
Protons and neutrons together make up virtually all of the mass of an atom, so we count them to figure out the mass. Counting protons alone will tell us what element and isotope the atom is, but counting neutrons alone tells us nothing.
What is the number of neutrons in elements of the periodic table?
you take the atomic mass of an atom say, 16 for oxygen, and subtract the atomic number, 8 for oxygen. 16-8= 8. so there are eight neutrons in the typical oxygen atom.
How are neutrons in an atom calculated?
As an example, take Americium 241 - 241 is the atomic weight. It is Atomic number 95 in the periodic table and so there are 95 protons. There are thus 241 -95 = 146 neutrons. That principle applies to all the elements.
Which take up the most space electrons protons or neutrons?
Electrons take up the least amount of space compared to protons and neutrons. Protons and neutrons are much larger in size compared to electrons and make up the majority of an atom's volume due to their mass.
How many neutrons does the nucleus of a nitrogen atom contain?
there are 7 neutrons because when you take away the number of protons, which is 7 as well, from the atomic mass, which is 14 when rounded, you get 7 which is the number of neutrons in nitrogen.
Can fission take place in the nucleus of hydrogen atom?
No, it cannot. Fission is the "splitting" of an atom, and a hydrogen atom will not fission. Some hydrogen atoms have a neutron stuck to the proton in their nucleus. Some even have two neutrons stuck to that proton. These neutrons can be "knocked loose" in something like a nuclear chair reaction in a weapon. The neutrons then can contribute to the building of the nuclear chain reaction. But fission doesn't happen to hydrogen.
How do you calculate the number of nuetrons in an atom?
The simplest way to do this is to find a periodic table which shows the mass of the atom, (the best choice is to find one which doesn't use relative atomic mass, have decimals), and take away the proton number, (it will be to bigger number take away the smaller number). This is because the mass of the atom takes into account usually only the protons and the neutrons. Therefore, if you take away the proton number, you are left with the mass of the neutrons.
Which of these makes up an atom's mass number?
The mass number of an atom is determined by the total number of protons and neutrons in the nucleus of the atom. It does not take into account the number of electrons, which are negligible in terms of contributing to the mass of an atom.
What are the subatomic particles found in the nucleus of the atom are?
The three subatomic particles found in an atom are the Protons, Neutrons, and Electrons. But the subatomic particles found in the nucleus of an atom are the Protons, and Neutrons. The Electrons surround the nucleus and take up most of the volume.
What does it take for an atom to be neutral or uncharged?
To have an equal number of protons and electrons, it has nothing to do with the number of neutrons!
Why we sum protons and neutrons for the atomic mass why we don't take neutrons?
Protons and neutrons together make up virtually all of the mass of an atom, so we count them to figure out the mass. Counting protons alone will tell us what element and isotope the atom is, but counting neutrons alone tells us nothing.
Why do you say electrons most affect an atom's size while protons and neutrons most affect an atom's mass?
because the electron are on the out side and orbit around the nucleus (aka protons and neutrons) and take up the space
How many nuetrons are on an atom?
it depends on which atom it is but you can figure out the number by looking at the periodic table. for example, sodium Na has an atomic mass of 11 (top no.) and a relative atomic mass of 23 (bottom no.), the top number represents the number of protons (and electrons as they are in equal amount) and the bottom number represent the number of neutrons and protons, so, if you take these away from each other you will be left with the number of neutrons the atom has. hope this helps :)

What particles take up most of the mass of an atom?
Protons and neutrons make up most of the mass of an atom. Electrons weigh almost nothing by comparison.
