The radius of a nucleus has quite a range completely dependent on the element or isotope under consideration. naturally, an element like uranium 235 (with 235 neutrons and 92 protons) will have a larger nucleus than hydrogen 0 (1 proton 0 neutrons). the range of these radii values however is normally somewhere of magnitude 10^-15 meters.

The radius of an isolated, neutral atom will range between 30 and 300 trillionths of a meter, or between 0.3 and 3 ångströms.

The atomic radius to the distance from the nucleus of an atom to?
The atomic radius is the distance from the nucleus of an atom to the outermost orbital of electron.
What is the atomic radius?
The atomic radii is an estimation of the radius of an atom. The value of the atomic radii is based off an approximation of the distance from the atom's nucleus to the edge of the atom's electron cloud.
Diameter of hydrogen atom compared to nucleus?
The ratio (for the covalent radius of the atom) is cca. 1/25000.
Which has lower ionization energy an atom with a small radius or an atom with a large radius?
Lower ionization energy would be associated with the larger atom, as the outer most electrons would be further from the nucleus, and not held as tightly.
What is used to represent the size of an atom using the distance from the nucleus to the outermost electron orbit?
Radius
The atomic radius to the distance from the nucleus of an atom to?
The atomic radius is the distance from the nucleus of an atom to the outermost orbital of electron.
Which neucleus is not within the radius of an atom?
A free proton is the nucleus of hydrogen atom and free alpha particle is the nucleus of helium atom and they may exist out side the atomic radius.
Measurement of an atom from the nucleus to the edge?
Atomic radius?
What is the atomic radius?
The atomic radii is an estimation of the radius of an atom. The value of the atomic radii is based off an approximation of the distance from the atom's nucleus to the edge of the atom's electron cloud.
Diameter of hydrogen atom compared to nucleus?
The ratio (for the covalent radius of the atom) is cca. 1/25000.
What is atomic center and atomic radius?
Atomic center is the center of the atom, also called as Nucleus. Atomic Radius is the distance between the center of the nucleus and outermost shell of the atom. It is nearly about 1.2 * 10-10 m.
The single proton that forms the nucleus of the hydrogen atom has a radius of approximately 1.0x10-13cm.The hydrogen atom itself has a radius of approximately 52.9 pm.What fraction of the space within?
The units for this question are 1.0x10-13 cm and the radius of the atom is 52.9 pm (pico meters) (the nucleus is -13 not -12).
Which has lower ionization energy an atom with a small radius or an atom with a large radius?
Lower ionization energy would be associated with the larger atom, as the outer most electrons would be further from the nucleus, and not held as tightly.
What is used to represent the size of an atom using the distance from the nucleus to the outermost electron orbit?
Radius
Does magnesium have a smaller radius than helium?
Atoms do not have a radius. A helium atom has a nucleus composed of at least two protons and maybe one or two neutrons. A magnesium atom nucleus (and every other atom on the periodic table other than hydrogen) is BIGGER than a helium nucleus. So if you look at it that way...magnesium is larger than helium
Where the protons neutrons and electrons are in an atom?
In an atom- the protons and neutrons are in the nucleus(aproximately centre) which makes the middle positively charged. The electrons are around the nucleus. The electrons are attracted to the nucleus because the nucleus is positively charged.
What is the center of an atom called?
The center of an atom is called a nucleus (nucleifor plural).Center of an atom is called the "Nucleus".
