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.
Sodium chloride, which is also known as salt, is a white color crystal with the molecular formula NaCl. Sodium chloride is an ionic compound. Sodium is a group 1 metal, thus forms a +1 charged cation. Its electron configuration is 1s 2 2s 2 2p 6 3s 1.odium and potassium are group 1 metals, which have the capability to make +1 cations. Chloride is the -1 anion made by group 7 element, chlorine. Since group 1 elements are electropositive and group seven elements are electronegative, their electronegativity difference is larger. So they form ionic bonds.
