in order of largest to smallest it is;
# neuron (cell in the brain) # molecule (made of multiple atoms)
# atom (made of protons, electrons, neutrons) # proton # neutron # electron
Atoms consist of, among other things, protons, neutrons, and electrons. Electrons are much smaller than protons which, in turn, are smaller than neutrons - though not by much.
An element theoretically can consist in nature as one atom. However, many elements in their pure form exist in nature as more than one atom. For example, pure Oxygen usually exists in nature as O2; pure Hydrogen usually exists as H2.
A compound is a substance which is made of two or more elements and can be separated into those elements by a chemical reaction.
So, bottom line, the things listed in the question in order of size from smallest to largest would be: electron, proton, neutron, atom, element, compound.
In order from largest to smallest:
- molecule (more than one atom)
- atom
- proton (part of an atom)
Compared to the (charge/mass) ratio of the electron:-- The (charge/mass) ratio of the proton is much smaller; although the proton charge is equal to the electron charge, the proton mass is much larger, by a factor of more than 1,800.-- The (charge/mass) ratio of the neutron is zero, because the neutron charge is zero.
The emission of a Beta particle has the effect of decaying a neutron into a proton and an electron. This increases the atomic number and the electron is ejected energetically. The number of neutrons are decreased by one and the number of protons increase by one, changing the atom to a different element.
The neutron is 0.16% larger than a proton.
an atom is larger than an element
(Chlorine, Fluorine, anything that gains an electron when it ionizes) For example: when F becomes F−, it gains one electron but has the same number of protons, meaning the attraction of the protons to the electrons is weaker, creating a larger radius.
Yes it is.
No, an electron is MUCH smaller than a neutron. About 1/1836 or something like that. Just Google "mass of an electron".
Helium
Compared to the (charge/mass) ratio of the electron:-- The (charge/mass) ratio of the proton is much smaller; although the proton charge is equal to the electron charge, the proton mass is much larger, by a factor of more than 1,800.-- The (charge/mass) ratio of the neutron is zero, because the neutron charge is zero.
Any compound will have a much larger mass than an electron. The mass of an electron is around 1/2000th that of a proton or a neutron. Compounds are made up of multiple atoms, which in turn are made up of multiple protons and neutrons (except in the case of hydrogen), so there is a considerable mass difference. It's interesting to note, however, that most of an atom's volume is actually made up of the electron cloud, which is the area within which electrons move about the nucleus. The nucleus, made up of protons and neutrons, is tiny in volume by comparison, even though it contains nearly all an atom's mass.
Platinum; it has two more electron shells than nickel.
A white dwarf is much larger than a neutron star.
The emission of a Beta particle has the effect of decaying a neutron into a proton and an electron. This increases the atomic number and the electron is ejected energetically. The number of neutrons are decreased by one and the number of protons increase by one, changing the atom to a different element.
Yes, a nebula is far larger than a neutron star. A neutron star is a few miles across. A nebula is light years across.
That's right, an electron microscope can produce more magnification than a compound light microscope.
The neutron is 0.16% larger than a proton.
An atom is larger than a neutron; a neutron is a part of any atom except a hydrogen atom.
