Question

Please explain ions to me

Answer 1

It is an atom or molecule which has either more electrons or less electrons in it depending on the charge.
(remove) We Ionize atoms by shooting photons with a certain amount of energy (corresponding to the e-level for a specific electron) which will ''eliminate'' that electron and the excess photons will be released as energy (which we then usually can see in the visible emission spectra)

Does that help?

Answer 2

can u plz show like a picture of an ion, ionic bond, and ionic bonding

Answer 3

hmm, do you know how Electron configuration looks like?

Answer 4

no

Answer 5

let's take an example:
Cr has 24 electrons. It's electron configuration is \[[AR]3d ^{5}4s ^{1}\]
\[Cr ^{2+}\] is an ion of Cr. It's charge is 2+ positive.
Since Cr 2+ is positive that means that we remove 2 electrons from it. making the electron configuration :
\[[Ar]3d ^{4}\] We have now removed 2 electrons from Cr making it an ion of Cr.

Does this help or do you need pictures?

Answer 6

Ar is Argon, it's atomic number (A) is 18.
From this we can see that argon has 18 electrons and 18 protons. So we start of with AR instead of doing the 1s, 2s, 2p, orbitals

Answer 7

pics plz and i didnt leran that stuff yet i need to know how to tell the Cr+ from looking at pics.

Answer 8

could u plz make a pic. of chemical bonds? how do i use both words in a sentence

Answer 9

chemical bonds and valence electrons

Answer 10

hello?

Answer 11

hmm... okey.
Well, there are different ways...

here you have just ''normal'' Cr without any ''charge''. We do the Aufbau principle(also know as buss seat rule) so that the orbitals with lower energy level gets filled first, therefore we put 1e- into 4s.
When we ionize Cr we remove 2 electrons, it's important to note that when we talk about ions the 4s orbitals will have increased level in energy, thus making it higher than 3d, and easier to remove.
As you can see 4s is higher in energy than that of 3d, so we remove an e from 4s, but there are no more e- to remove from that so we take one from 3d. We usually take the e- which is highest in energy.
