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 density around a partial positive electron atom compare to the density of a partial negative?
The density around a partial positive electron atom is higher compared to a partial negative electron atom. This is because in a partial positive atom, electrons are being pulled towards the nucleus due to the partial positive charge, leading to a higher electron density around the atom. In contrast, in a partial negative electron atom, electrons are being pushed away from the nucleus, leading to a lower density around the atom.
How does the nucleus of a copper atom compared to the nucleus of a nickel atom?
copper has more protons than nickel
Electrons farther from the nucleus are said to be of?
Electrons farther from the nucleus are said to be of higher energy levels or higher orbitals. This means they have more energy and are less tightly bound to the nucleus compared to electrons closer to the nucleus.
Why is the density of an oxygen nucleus much greater than that of oxygen gas?
Almost all of the mass of an atom is concentrated in the nucleus (a nucleon weighs about 2000 times more than an electron) and almost all of an atom is empty space; the nucleus is much smaller than an atom. And a gas also is composed almost entirely of empty space between the atoms or molecules. So the density of an oxygen nucleus is vastly greater than that of oxygen gas.
What is the dense center of the atom called?
the denser part of an atom is the nucleus. about 99% of the mass of an atom is concentrated within the atom.
What statement best describes the density of an atom's nucleus?
The nucleus of an atom is highly dense, containing nearly all of the atom's mass in a tiny volume. It consists of protons and neutrons packed tightly together. The density of the nucleus is about 100,000 times greater than the overall density of the atom as a whole.
How does the density around a partial positive electron atom compare to the density of a partial negative?
The density around a partial positive electron atom is higher compared to a partial negative electron atom. This is because in a partial positive atom, electrons are being pulled towards the nucleus due to the partial positive charge, leading to a higher electron density around the atom. In contrast, in a partial negative electron atom, electrons are being pushed away from the nucleus, leading to a lower density around the atom.
What best describes the nucleus of an atom?
It’s the most massive part of the atom
Why is the density of the nuclear mass more than that of atomic mass?
The density of the nuclear mass is higher than that of the atomic mass because atoms are mostly empty space with the majority of their mass concentrated in the nucleus, which is extremely dense. The nucleus contains protons and neutrons tightly packed together, leading to a much higher density compared to the overall atomic mass spread out over the atom's volume.
What is the term for the region of very high density in the center of the atom?
that is the nucleus. It is in the middle
Can an atom lose its nucleus?
Atoms can lose part of their nucleus, but they can't lose their whole nucleus.
What is true of an atom's nucteus?
A nucleus of an atom is at its center, it consists of protons and neutrons. The nucleus is roughly 10,000 times smaller than the whole atom.
Why is iron heavy while sodium is light?
The density of an element depends on the number of the nucleons (protons and neutrons) in the atom nucleus.
Why an excited atom is electrically neutral?
An excited atom is electrically neutral because the number of protons in the nucleus is equal to the number of electrons surrounding the nucleus. When an atom becomes excited, its electrons move to higher energy levels but the total negative charge from the electrons is still balanced by the positive charge from the protons, maintaining the atom's neutrality.
What is the center to an atom?
The center of an atom is the nucleus containing protons and neutrons. The nucleus is surrounded by electrons in the electron cloud, but the nucleus is roughly 10,000 times smaller than the whole atom. In theory, most of an atom is empty space.
Is an atom in the nucleus higher and more polluttive than metane?
Sorry, don't understand your question. An atom is not in the nucleus, but an atom is composed of a nucleus and electrons surrounding it. What do you mean by metane? Please rethink question and resubmit
How does the nucleus of a copper atom compared to the nucleus of a nickel atom?
copper has more protons than nickel
