SQL Server automatically converts the data from one data type to another. For example, when a smallint is compared to an int, the smallint is implicitly converted to int before the comparison proceeds. Note that the query optimizer may generate a query plan to perform this conversion at any time.
The heaviest known alkaline earth metal is radium, atomic number 88... It's from Mastering Chemistry and I have tried multiple times but I cannot seem to get it... Please help me (:
This is due to the similar electronic configuration (more importantly the number of valence electrons). Among the two groups given here, choice (b) Mg, Sr and Ba are alkaline earth elements (part of group IIA) in the periodic table. Other elements of this group are Be, Ca and Ra. All these elements form the alkaline earth metal group of the periodic table. All these elements have 2 valence electrons, which they can give up to attain a +2 charge as cations. They have certain common properties, including shiny and silver-white appearance.
