Where is the most of the volume of an atom found at?
If we are talking about an atomic nucleus, it very much depends on which element in the periodic table. However, the volume of an atomic nucleus is so very small compared to the volume of the entire atom that it is next to nothing and the actual numbers are rather meaningless. An atomic nucleus has a diameter of somewhere around 1 to 10 femtometres (ten to the power minus 15 metres) and if considered as a sphere, the volume would be calculated using the formula 4/3 times pi times (half the diameter) cubed. Mind-bogglingly small.
What is smaller electron or nucleus?
Atomic nuclei are much-much smaller than cell nuclei.Why? Because a cell nucleus contains an enormous number of molecules, each molecule built from a number of atoms, with every single atom containing a tiny little (atomic) nucleus. For instance, an oxygen atom (which is a common component of living cells - think about water, H2O) is about 20 thousand times larger in diameter than its (atomic) nucleus.Actually, if you magnified a typical cell nucleus (6 μm of diameter for average mammalian cells) to the size of the Earth (diameter of Earth: 12756.2 km), then the oxygen's atomic nucleus (actual diameter: 5.4 fm) would look like a half-inch (12.8 mm) ball at the same magnification.That means that - as far as size is concerned - the atomic nucleus compares to the cell nucleus as a blueberry (or a smaller hazelnut) compares to our planet.
Where is most of the mass located in an atom?
By far it is in the nucleus. Neutrons are very slightly more massive than protons, but not all atoms have neutrons. All atoms will have at least one proton. Protons and neutrons are both much, much more massive than electrons. Relatively speaking.
The volume of an atom is determined by the size of its?
It can be determined by the size of it's electron. The reason for this being is because of the mass that is calculated by the protons to the neutrons of the atoms within the nucleus.
Is the density of the nucleus higher than that that of the whole atom?
The nucleus of an atom has a phenomenally high density! Consider the nucleus of Hydrogen, (a proton). This has a mass of approximately 1.67 x 10-27kg, and the radius of this nucleus is approximately 10-15 m. Therefore, on the assumption that the nucleus is spherical, the volume of the nucleus is given by the volume of a sphere; Volume = (4/3)(PI)r3 , Mass = 1.67 x 10-27 kg, Density = Mass/Volume Therefore Density = [1.67 x 10-27 kg]/[(4/3)(PI)r3] substituting in; PI = 3.1416, r = 10-15 m This yields; Density = 4 x 1017 kg m-3 !!!! This is almost equal to a million million million kg m-3 or a thousand million million tonnes m-3 !!!!
How does the volume of a nucleus to the volume of an atom?
the volume of atom is much greater than that of nucleus
How does the volume of a nucleus compare to the volume of an atom?
the volume of atom is much greater than that of nucleus
How much of the atom does the nucleus make up?
verry verry small amount
What is the mass of the nucleus compared to the mass of the entire atom?
The difference between the mass of the nucleus and the mass of the atom is virtually negligible.The atom is mainly empty space! The radius of the atom is ~10 000 times the radius of the nucleus.That means that the volume of the atom:volume of the nucleus = 1000 000 000 000:1 or= 1012:1Think about the volume of a grain of sand to the volume of a football stadium if the stadium was a complete three dimensional sphere type structure.
Which is a true statement about the atomic nucleus. It takes up most of the volume of the atom. It contains protons neutrons and electrons. It contains most of the mass of the atom?
The first two statement are false. The other one is true. There are electrons outside the nucleus, but they are much lighter than the particles in the nucleus.

Is the electron cloud the most massive part of the atom?
No, it is not. Almost all of the mass of an atom is located in the nucleus. The proton, that carrier of the positive electrical charge, is some 1836 times more massive that the negatively charged electron that it attracts to "build" an atom. If we take a look, we'll find that in a simple hydrogen-1 atom, a single proton is in the nucleus and a lone electron makes up the electron cloud. And the nucleus is about 1836 times more massive than the "rest" of the atom. In a helium-4 atom, two protons and two neutrons form the nucleus and a pair of electrons form the electron cloud. In this case, the nucleus is about 7,444 times as massive as the electrons. As we move up the periodic table, the figure gets even more lopsided.
An electron is much larger than an atom?
an electron is much much smaller than an atom. An electron is a portion of the nucleus in an atom.
How much bigger is an atom compared to its nucleus?
The atom is about 10,000 times as big as the nucleus.
What subatomic particle occupies the most volume in the atom?
the vast majority of the volume of an atom is filled with absolutely nothing there is a central heavy nucleus and "whizzing" round it are a number of much lighter much smaller electrons. from the outermost reaches of the electrons orbits to the centre of the nucleus there is an awful lot of "nothing" an analogy is to consider the earth we are a heavy central body - compare us to the nucleus of an atom whizzing round us are various satellites - the moon and many small artificial ones we have put up - compare them to the electrons in between and making up by far the bulk of the volume occupied by the "earth and its satellites" is a lot of nothing - just like in an atom
What is larger a carbon atom or nucleus?
the nucleus is a very small object at the center inside an atom. the atom is much larger. this is true for all elements, not just carbon.
Is the nucleus light or heavy?
The nucleus is pretty much light. But it contains the most mass of an atom.
