What is an ion?

Answer 1

An ion is a charged atom or molecule. It is charged because the number of electrons do not equal the number of protons in the atom or molecule. An atom can acquire a positive charge or a negative charge depending on whether the number of electrons in an atom is greater or less then the number of protons in the atom. The web source below has some pictures explaining this too.

Answer 2

It's the positive lump of a chemical compund once an electron has been knocked off of it. So ionic water (molecule H20) is ion H30+. Alternative definition is a pub in Sawbridgeworth,Herts which has had a letter missing on the Bell St sign for ages and rather than being the White Lion is the White ion.

Answer 3

An ion is an atom that has the wrong number of electrons. Either it has too few electrons for teh number of protons in it's nucleus, or too many.

For example, Lithium has 3 protons in it's nucleus, and 3 electrons in it's outers shells. But it can easily bond with Flourine, with 9 electrons, donating one of it's own to the Flourine, and losing one. It would be an IONIC bond, where Lithium would end up with only 2 electrons in it's shell, and Flourine would end up with 10. The Lithium would end up with a net positive charge of +1e (the unit of charge held by the electron/proton,) and the Flourine would end up with a net negative charge of -1e, while the two of them would remain neutral when taken together. Another example is Sodium and Chlorine, which ionically bond together to form table salt.

It's also possible for an ion to be created without an ionic bond. A high-energy particle could collide with an atom, knocking off one of the outermost electrons. This would result in a naked ion that has a net charge on it's own.

Answer 4

An ion is an atom or group of atoms, normally electrically neutral, that has lost or gained one or more electrons. The simplest ions are the proton (a hydrogen ion, H+, positive charge), and alpha particle (helium ion, He2+, consisting of two protons and two neutrons). An ion consisting of a single atom is called a monatomic ion, and an ion consisting of multiple atoms is called a polyatomic ion. Larger ions containing many atoms are called molecular ions. The process of converting electrically neutral atoms or molecules into ions and the state of being ionized is called ionization. The recombining of ions and electrons to form neutral atoms or molecules is called recombination.

Answer 5

An Ion is an atom with either a n electron removed or an extra one.
This typically happens when an "Ionic Salt" is dissolved.
As an example common salt (Na Cl) consists of an atom of Sodium (Na) and Chlorine(Cl) when in a dry salt they are arranged in a Chrystal latice. Sodium has a group of electrons whizzing around the nucleus plus one spare one; whereas Chlorine is missing one electron from its outer electron group.
So while in the crystal latice they fool each other by sharing the odd Sodium electron; however when salt is dissolved the Chlorine runs off with the odd electron from the Sodium.
This means that the Chlorine atom has a negative charge caused by the extra electron, and conversely the Sodium has a positive charge by the lack of an electron.
Hope that helps

Answer 6

that quite often relies upon on the quantity of cost each and each ion incorporates...right here we assume that the two ions in question CAN certainly combine....... for eg. a million. if a favorable ion with a single cost combines with a unfavorable ion with a single unfavorable cost, you get a independent molecule, i.e. it has no cost. 2. if a dipositive ion( with 2 beneficial fees) combines with a unfavorable ion with a single cost, you get a molecule with a single beneficial cost.( certainly, even this is declared as a favorable ion, because of fact it incorporates cost) you will locate that the quantity of cost( a million+, 2+, a million-, 2- and so on) governs what you "get" after reaction.

Answer 7

Ion is an atom or group of atoms that carries a positive or negative charge as a result of having lost or gained one or more electrons. I hope this is helpful.

Answer 8

An ion is a positively or negatively charged atom.

Answer 9

As the subject is covered, an ion is what my mum uses to take the creases out of my clothes.

Answer 10

an ion is either a positively or negatively charged particle or atom
