Alkaline Earths

The Alkaline Earth Metals are the second group of the periodic table of the elements. They are highly reactive and share many properties with each other. In this category, there are ANY questions that have to do with the alkaline earths, or their elements: Beryllium, Magnesium, Calcium, Strontium, Barium, and Radium.

Does beryllium form only covalent bond?

A covalent bond is a bond between 2 non metals or semi-metals.

Beryllium can form ionic compounds with nitrates forming Be(NO3)2

So no beryllium does not form only covalent bonds.

Why is the ionization energy of boron less than beryllium?

The rise in ionisation energy is not regular. To explain this we must remember that the second shell of electrons is actually subdivided into 2s and 2p. The most easily removed electron in Boron is that in the 2p orbital, higher in energy than the 2s electrons in Beryllium. It therefore needs less energy for total removal than does the 2s electron of Boron. This outweighs the effect of the increased nuclear charge of Boron, which tends to make its outer electron harder to remove.

more reactive

Is beryllium fluoride polar?

BeF2 is non-polar as it is (strangely) covalent in nature and as such, the molecule has a linear shape which produces a non-polar molecule.

Alkaline-earth metal do not react with oxygen?

Yes, they do. Actually, they react violently when heated and in the presence of oxygen.

Is the alkali metal more reactive than an alkaline-earth metal?

Yes, alkali metals are more reactive than alkaline-earth metals. All atoms want to have 8 electrons in their outer shells. Alkali metals have to give one electron away, where as alkaline-earth metals need to give two away which is less energetically favorable.

Why is the first ionisation energy of beryllium lower than the second?

The p orbital is slightly higher in energy than the s orbital. That why, it's easier to remove the 2p1 elecrtron from B, therefore the 1st ionisation energy in B will be lower
