which is the reason that ionic compounds are brittle?

the bonds between the anions and cations are weak and therefore easily broken.

a strong repulsive force is created when cations suddenly align.

they involve positive metal ions in a sea of delocalized electrons.

they share electrons, which makes the bond brittle.

Astudent made the lewis dot diagram of a compound shown. what is the error in the lewis dot diagram? a)an o atom should transfer all of its six electrons to mg because the formula is mgo b) both electrons of mg should be transferred to one o adam because the formula is mgo c) the electrons should be transferred from each o add him to capital mg because mg has fewer electrons d) the number of dots around mg should be four because it has to transfer two electrons to each o

What must happen before a body cell can begin mitotic cell division

Which is a characteristic of the electron sea model for metallic bonding? molecular orbitals overlap to produce bands. electrons flow easily between metal nuclei. electrons are in fixed positions in the orbitals. atomic nuclei are arranged in an irregular pattern.
