1. The results of determining the alkaline and alkaline earth metals in the treated gasoline showed there was no loss of metals from the catalysts.

2. Strontium Chemical element, one of the alkaline earth metals, chemical symbol Sr, atomic number 38.

3. Beryllium : Chemical element , lightest of the alkaline earth metals, chemical symbol Be, atomic number 4.

4. In this paper, chemical storage materials of hydrate of alkaline earth metals at low temperatures are rported by differential scanning calorimetry (DSC).

5. The high sustainability against coke formation may be partly due to the mobile oxygen as well as due to the presence of alkaline earth metals in the perovskite supports.

6. More broadly, ammonium hydroxide (see ammonia) and soluble hydroxides of the alkaline earth metals are also called alkalies.

7. But the fact that the excess bariums are responsible for electron emission may be reconciled with the deficiency of alkaline earth metals during life by the dynamical surface emission center model.
