which combinations of atoms tend to form ions? why? what types of elements form ionic bonds? how?

Question

could you explain this please? thanks

Answer 1

metals and non metals form ionic bonds... NaCl (sodium chloride) for example forms an ionic bond. All atoms want to gain a valence of 8 electrons in their outer electron orbital. In order for Sodium to do this, Sodium must donate one electron to become Na(+) and Chlorine must gain one electron to become Cl(-).

Answer 2

The note reliable isn't helpfull i'm afraid. What you're saying contained in the 0.33 paragraph is on the fringe of the truth. All atoms/ions opt for an entire outer shell, to attempt this sodium needs to lose an electron and change into Na+ it may try this via forming an ionic bond with a collection 7 element like chlorine. with slightly of success you'll do a touch experiments the position you inspect crew one metals at GCSE, you may discover from sodiums reactions with water it isn't what you would call "reliable", NaCl is the significant constituent of table salt although and is extra "reliable" yet in case you dissolve it there are nevertheless some reactions it may participate in. in words of the merely accurate tip you ask for the fashion of electrons in an aspects outer shell is an similar because the crew that is in (it really is real for the first 20 aspects untill the transition metals commence yet you merely problem about the first 20 at GCSE, a minimum of you probably did 2 years in the past when I did it, the merely different exception is helium. It has 2 electrons in its outer shell yet because it really is the first shell and is for this reason finished that is often seen as inert (or perhaps reliable :-P) and so is put in a similar crew because the noble gases.
