tract as in the dolichosaurs, are also noticeable in the aigialosaurs, though to a weaker extent; but what the aigialosaurs always lack is the deflection or folding-over of the tail which is common in the dolichosaurs.
Sodium chloride is an ionic compound that is produced by the bonding of sodium cations to chloride anions. This salt dissolves readily in water and forms crystals when in solid form. Uses of sodium chloride can be both commercial and biological.
Yes it does have an ionic bond. Yes, sodium chloride does have an ionic bond. Sodium chloride, table salt, NaCl is an ionic compound formed by the elements Sodium - Na and Chlorine - Cl. For both elements to obtain a full outer shell (8 electrons) and form an ion, Sodium would have to LOSE an electron and Chlorine would have to GAIN an electron.
