What are the properties of ionic bonding?

they form crystals

They have high melting and boiling points

They are hard and brittle

Conduct electricity when dissolved in water

Good insulators

Ionic Compounds have high boiling and melting points as they're very strong and require a lot of energy to break.

Explanation:

The electrostatic forces of attraction between oppositely charged ions lead to the formation of ions.

Ionic compounds form crystals. These compounds are brittle and break into small pieces easily.

it is to be noted that an alpha particle is an helium nucleus. so it contains 2 protons 2 neutrons and has a mass number of 4. when alpha decay particles are ejected from the nucleus it gets transformed into an atom which has atomic number less than 2 and a mass number less than 4.

an equation that could represent alpha decay is radium 226 decay of alpha particle forms radon 222.
