•oppositely charged ions attract.
•two atoms share two electrons.
•two atoms share more than two electrons.
•like-charged ions attract.

2. Which pair of elements is most likely to form an ionic bond?
•hydrogen and helium
•lithium and potassium
•potassium and iodine
•iron and zinc

3. Ionic compounds are normally in which physical state at room temperature?
•solid
•liquid
•gas
•plasma

Respuesta :

1. Oppositely charged ions attract.
2. Potassium and iodine (because ionic bonds are nonmetal + metal).
3. Ionic compounds are normally solid at room temperature.

Ionic substances are formed by transfer of electrons from one atom to another.

Ionic bond is formed when one atom (usually a metal) donates an electron to another atom (usually a nonmetal) to form an ion pair. This implies that an ionic bond is formed when oppositely charged ions attract.

Ionic bonds are commonly formed between metals and nonmetals because metals loose electrons easily and nonmetals accept electrons easily. Hence, potassium and iodine will easily form an ionic bond.

Ionic compounds are mostly solid crystals which have high melting and boiling points. At room temperature. the physical state in which ionic substances are found is mostly solid.
