What is the difference between diffusion and ion implantation?
Diffusion is the mixing of two materials by the natural movement
of the particles.
Implantation is a forced action for the introduction of an item (or partcle) in other object (material).
diffusion is high temperature process while ion implantation is low temperature process
Ion implantation can be the effect of ion irradiation.
Doping levels can be precisely controlled since the incident ion beam can be accurately measured as an electric current.
The Diffusion Potential is the potential difference across the boundary b/w two electrolytic solutions of different compositions The Nernst Potential is the diffusion potential across a membrane that exactly opposes the net diffusion of a particular ion through the membrane
It would actually just be facilitated diffusion and diffusion. Facilitated diffusion needs an ion pump or a protein channel, but diffusion doesn't need anything like that. Materials that use general diffusion can cross the cell membrane without energy or any special attention from the cell.
Ion channels can act as gated channels which help facilitated diffusion occur.
What is the difference between ammonia gas and an ammonium ion?
I actually don't think it does. Diffusion is normally controlled by mass, and sodium atoms being less massive than chlorine atoms should diffuse more rapidly (the difference in mass between the neutral atom and the ion isn't enough to matter).
An ion has a charge, a molecule doesn't.
When it comes to Aquaporin proteins, it allows polar water molecules to get past the hydrophobic middle of the cell membrane. Also, when it comes to Ion channels, Membrane proteins create a tunnel through ehich can pass them. However, Ion Channels allow charged ions to get6 past the hydrophobic center.
Facilitated diffusion, or diffusion through ion channels, is not a form of active transport. It is a spontaneous passive transport.
The chloride ion has the formula Cl-, and is a monatomic ion. The chlorate ion has the formula ClO3-, and is a polyatomic ion.
The sulfate ion is SO42- The sulfite ion is SO32- and is more basic that sulfate.
An ion is an atom that has lost or gained an electron.
Sulphate is SO42- ion sulphide is S2- ion
Nitrate ion is NO3-1 while Nitride is N-3.
NO2−, nitrite ion NO2+, nitronium ion
Chlorite is ClO2- ion whereas chloride is Cl- ion
All are ions: - hydrogen ion H+ - hydroxide ion OH- - hydronium ion H3O+ , which is a type of oxonium ion
They are both types of passsive transportation.

The ion biphosphate is (HPO4)2-. The ion pyrophosphate is (P2O7)4-.
An n-type semiconductor is formed by doping a pure semiconductor (silicon or germanium, for example) with atoms of a Group V element, typically phosphorus or arsenic. The dopant may be introduced when the crystal is formed or later, by diffusion or ion implantation.
when an atom loose electron it become negative ion and when it gains electron it become positive ion
The difference between the number of protons in all the atoms contained in the ion and the number of all the electrons contained in the ion.
A hydrated ion, is an ion that is surrounded by water molecules. The water molecules are attracted to the opposite pole of the ion. Such as negative to positive.
What is the difference between carrier proteins in facilitated diffusion and carrier proteins that act as pumps?
Carrier proteins in facilitated diffusion need a concentration gradient. For example if you need the ion A+ in a cell, then there has to be a lower concentration there then the media from which you extract it. Carrier proteins that act as pumps are usually used when a higher concentration is for example in the cell as opposed to the media from which it is extracted. Also pumps act 2-ways (eg: Na+-K+ pumps), meaning as… Read More
The difference between a simple radical and an ion is that a radical has an unpaired electron, but does not carry a charge. Ions are atoms or molecules with net electric charge from gaining or losing electrons.
A chlorine ion has one less electron, giving it a +1 charge.
Its an active transport and use sodium channel generally _____ Diffusion is itself a pathway of travel across a cell membrane. Diffusion can be "simple diffusion" which is simply an ion moving across the membrane anywhere, or "fascilitated diffusion", where an ion moves across the membrane in a specific channel. Either way, diffusion involves the movement of that ion along its concentration gradient and requires no energy. Active transport is not the same as diffusion… Read More
a molecule is two or more atoms combined. a molecular ion has a valence charge. an example of a molecular ion is sulfate ion or ammonium ion. they both have a charge.
An ion is a particle with only one charge, either positive or negative. A dipole has both.
The Phosphide ion has 3 electrons more than the Phosphorus atom
NADPH has a Hydrogen ion and NADP+ does not.
The number of electrons.
Diffusion occurs in the human body in a variety of ways. Examples of diffusion are through respiration, ion movement and the diffusion of nutrients in the kidney and small intestine.
Chlorate is the polyatomic ion ClO3-, chloride is the monatomic ion Cl-.
the ion has one less electron. Na^0 vs Na^+1
The pH value of a particular solution is equivalent to -log[hydrogen ion concentration].
Sodium ions have a +1 charge, whereas calcium ions have a 2+ charge.
An ion is a compound or an element with an electric charge.
positive ion forms when any electron removes from an atom and an anion called negative ion forms when an atom accepts an additional electron
Sulfate is a polyatomic ion with the formula SO42- Sulfite is a polyatomic ion with the formula SO32- Sulfide is a monatomic ion with the formula S2-
A liquid junction potential is a potential difference between two solutions caused by the diffusion of an ion faster than the other. Salt bridges between these solutions containing high concentration of salts (eg. KCl, KNO3, NH4NO3) with ions that diffuse at the same rate minimising this effect.
Facilitated diffusion occurs against the osmotic potential/concentration gradient and requires energy at the expense of the ATP hydrolysis. There are several way in which this diffusion could occur in the cells. The first one being the ion exchangers. The ion exchangers are coupled with ATPase activity and they exchange ion(s) across the membrane. The most classical example of ion exchanger is the Na+/K+ ion exchanger and Ca+ ATPase. Other way of the facilitated diffusion in… Read More
an ion has a different number of electrons and an isotope has a different number of neutrons then listed on the periodic table or your sample
Chloride is an ion of chlorine plus one electron. In solution, calcium is an ion missing two electrons.
Covalent is when electrons are shared. Ionic is when the negative ion gives an electron to the positive ion.
A carbonate ion is CO3 with a anion of 2- whereas a hydroxide ion is OH with an anion of - Hope this helps.
