metal - Which has more metallic character: aluminium …

2013/10/6· These properties are harder to predict: In this case, however, A l has a more metallic character compared to M g. Mg is more metallic than Al due to its tendency to lose electrons. As a result, the electropositivity decreases as we go across periods. Electropositivity is related to metalic character and vice versa.

Sodium Carbide | AMERICAN ELEMENTS

Carbides are compounds in which the anion is one or more carbon atoms. Most metals form carbide compounds, though not all: Indium and Gallium , for example, do not. Like diamond, a pure carbon substance, carbide compounds tend to be extremely hard, refractory and resistant to wear, corrosion and heat, making them excellent candidates for coatings for drills and other tools.

How do the atoms coine in CaCl2 or Calcium Chloride?

Answer. An ionic bond is formed in a molecule when one atom in the molecule transfers its one or more electrons from itself to its neighboring atom in the molecule. In this molecule, calcium transfers its two electrons to its two neighboring chlorine atoms and hence C aC l2. . is an ionic compound.
