positive ion + negative ion =?

Question

if a positive ion and a negative ion is combined, what does it become?

Answer 1

a compound held together with an ionic bond

eg. Na becomes Na+ PLUS e-
Cl PLUS e- becomes Cl-

Na+ PLUS Cl- becomes NaCl

Answer 2

that largely depends on the amount of charge each ion carries...here we assume that the 2 ions in question CAN actually combine.......

for eg.
1. if a positive ion with a single charge combines with a negative ion with a single negative charge, you get a neutral molecule, i.e. it has no charge.

2. if a dipositive ion( with 2 positive charges) combines with a negative ion with a single charge, you get a molecule with a single positive charge.( actually, even this is called a positive ion, since it carries charge)

you can see that the amount of charge( 1+, 2+, 1-, 2- etc) governs what you "get" after reaction.

Answer 3

It has to do with the amount of electrons in their outer energy level. For example, O has 6 electrons in its outer shell, so in order to have a full outer energy level it can either gain 2, or lose 6. Obviously its easier to gain 2, so it will make a negative ion. You can predict the behavior by calculating how many electrons an atom will have to lose or gain to have a full shell.

Answer 4

a normal molecule as long as it is +1,-1 or +2,-2, ect

Answer 5

A salt

Answer 6

an ionic compound with a crystal lattice structure.

Answer 7

an ionic salt

Answer 8

they become UBER ION MAN!!! striking fear into the heart of all non covalent bonded atoms!!!

Answer 9

an ionic crystal

Answer 10

ionic bond,

usually salt. but not always salt
