7th period because atomic size down the group increases.
And Alkali Earth metals are found only in Group 1.
The element is in Group 1 and period 7
Alkaline earth metals are in the 2nd column of the periodic table. They can lose up to 2 electrons without having to pull electrons out of an inner shell, and so alkaline earth metals almost always have a charge of +2
The injuries she had from a traffic accident, which prevented her from having children. Also the infidelity of her husband Diego.
Transition state metals include a wide variety of metals; they include iron, gold, and mercury which all have strikingly different properties (hard, soft, and liquid, for example). Nonetheless, a comparison can be made between the transition state metals and the alkali and alkaline earth metals; transition state metals are not as chemically active (some transition state metals are actually inert, such as platinum).
