Form crystals.HIgh boiling point and melting pointsBad conductors of electricityHigh hardness

Explanation:

Just a brief introduction to remember what the ionic compounds are. Ionic compounds are the compounds formed by ionic bonds, i.e. the eletrostatic attraction between cations (positivie ions) and anions (negative ions). The ionic compounds are mostly either oxides or salts. An example of an ionic oxide is CaO, and an example of an ionic salt is NaCl.

The strength of the ionic bonds is responsible for most of the characteristics of these compounds. These are the most common characteristics that solid ionic compounds share:

They form cristals: the ionic compounds form long networks of atoms very organized, instead of individual units. That is why you must not refer to these compounds as molecules.HIgh boiling and melting points: because high energy is required to separate the ions, and form the new state.Bad conductors of electricity: since the ions are in fixed position, they do not carry charges (the charges are not moving), so in solid state, the ionic compounds are bad conductors (but in aqueous solution they are very good conductors).Hardness: crystals are relatively hard and when they are hammered they brake apart.

odds are decent that your handwriting right now looks a little bit different than it did five years ago, and will look different again in five more. when i look back through my notebooks from middle school to now, i see a long, slow progression from meticulous and teeny letters to bigger, sloppier ones, plus a few side detours: sometime in high school, for example, i decided those loopy cursive lowercase f’s were just the coolest, adopting them as the lone rep for cursive in my otherwise all-print handwriting.

I’d have to say no because without oxygen in the water the fish would all be dead. so if you want to fish for dead fish, pick the ponds with the lowest oxygen concentrations.
