How are ionic compounds formed?

Answer 1

All compounds are either positive or negative. Alkaline compounds are negative and acid compounds are positive. Look in the Periodic Table to find the compounds' chemical formula you are looking for. You want to form ionic compounds; so say you wanted to work out the formula for zinc nitrate. Zinc is Zn2+ and nitrate is NO3-. You use the Zn and take the 2 out. You don't with the nitrate because there is nothing to swap; the 3 is already converted so you don't swap that. You can't literally add the 2 from the zinc onto the 3 so you have to use brackets. Zn goes at the front of the formula because it isn't in brackets. So... Zn(NO3)2. The 2 goes outside the brackets because it cant be literally added on.

Answer 2

• packed together in a regular pattern
• oppositely charged ions attract one another strongly
• each + ion is placed next to - ion
• have a formula unit to show the ratio of ions

Ionic compound has a giant ionic structure in which there are strong ionic bonds between cations (positively charged ions) and anions (negatively charged ions).

[Ionic bonds are the strong non-directional electrostatic attractive forces between cations and anions. An ionic bond can be formed by the transfer of outermost shell electrons from one atom or a group of atoms to another.]

Answer 3

Ionic compounds form a definite crystal structure.

Answer 4

the compounds formed by ionic/electrovalent bonding are called ionic bonds .. was this what you needed ? or u need to know what is ionic/electrovalent bond ?

Answer 5

Ionic compounds are formed when two oppositely charged particles are attracted to each other.

Answer 6

they form a salt structure like a lattice and they use it for good purposes

Answer 7

Ionic compounds which consist of crystal lattices.

Answer 8

Molecules
