How would you predict the properties of sodium chloride compare with those of its constituet elements?

Sodium is a metal. Chlorine is a non-metal.

Sodium chloride should be an ionic compound.

IThe physical properties of sodium chloride should be

•solid

•high melting and boiling points

•brittle

•poor conductor of electricity

•aqueous solutions should be good conductors of electricity

The physical properties of sodium are

•solid

•metallic lustre

•malleable and ductile

•good conductor of electricity

The physical properties of chlorine are

•pale green gas

•low melting and boiling points

•poor conductor of electricity

hey your not cool]      

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.
