Mg (magnesium)
The element that would have properties most similar to the new element would be an element that lies in the same group as the new element. Specifically, the element with the most similar properties will lie directly above or below that element in the group.
Neon (Ne) would have properties most like helium (He) because they are both noble gases in the same group of the periodic table, with similar electron configurations and chemical reactivity.
Mg (magnesium)
Strontium (Sr) would react most like calcium (Ca) because they are both in the same group (Group 2) of the periodic table and share similar chemical properties.
Ge Germanium

Mg (magnesium)
the most important properties in an element is state at room tempreture
Mg (magnesium)
Those elements that are also is group II of the Periodic Table, namely Be, Mg, Sr, Ba and Ra.

nonmetals
Calcium is an element that behaves most like magnesium due to their similar chemical properties. They are both alkaline earth metals, have similar reactivity, and form similar compounds.
