8x10^-15-1x10^-12
The nucleus of an atom only makes up a tiny fraction of the total volume of the atom, typically less than 1%. The majority of an atom’s volume is composed of the electron cloud surrounding the nucleus.
Adding a neutron increases the atom's mass by about 1 AMU assuming it remains stable.
Im assuming you mean protons because phosphorus is its own atom... but anyway phosphorus has 15 protons in its nucleus
Oxygen has 8 electrons (assuming its charge is 0), and in the first shell ("closest" to the nucleus) there are 2 electrons. :)
The center of the atom, where protons and neutrons are located, is called the nucleus. It contains most of the mass of the atom and is positively charged. The electrons orbit around the nucleus in energy levels.
The nucleus has a width on the order of 10^(-15) meters, while an electron is (on average) a distance of 10^(-10) meters from the nucleus. If you were to magnify the nucleus to the size of a baseball, the electrons would be orbiting at a distance of around 1000 meters. That is, there are about 50,000-100,000 nucleus diameters to the electron's average radius.
Assuming you mean "nucleus", the answer will depend on what what nucleus you are talking about (atomic nucleus, the nucleus of a cell, etc.).
Assuming you mean "nucleus", the answer will depend on what what nucleus you are talking about (atomic nucleus, the nucleus of a cell, etc.).
The answer will depend on what nucleus the question refers to. The nucleus of a cell is quite different from a nucleus of an atom. which differs from the nucleus of an organisation.
Assuming that's the nucleus of an atom, the answer is "electrons". They are in "clouds", sort of, around the nucleus of atoms.
Assuming you mean a nucleus, yes, all living organisms have a nucleus, which is the centre of a cell and is the control centre of it.
The size of a nucleus may be measured by firing sub-atomic particles at the nucleus and counting the proportion that bounce off the nucleus rather than miss it entirely. Assuming that the nucleus is spherical in shape, the ratio allows its size to be estimated.
Assuming you're referring to the epithelial lining of an animal that does indeed have cheeks, the cell is eukaryotic because it has a nucleus. Prokaryotic cells have no nucleus.
Assuming that "plus 19" refers to exactly 19 protons, the answer is Potassium.
Protons and (mostly) also neutrons (same or more in number), all together in the nucleus.Electrons (same number as protons) orbiting around the centered nucleus in shell's with discrete diameters
The nucleus of an atom is much smaller than the volume of the entire atom. The nucleus makes up only a tiny fraction of the total volume, with the electrons surrounding the nucleus occupying the majority of the space.
Assuming the initial speed of the neutron was the same (and assuming they really bounce, which I am not quite sure): less. When bouncing off a hydrogen nucleus, more momentum will be transferred to the hydrogen, because of its lower mass. Most of the momentum will be transferred, in fact, since the masses are more or less equal.
