Mg
Silicon, which is just below carbon, and Germanium are the two elements that are most like carbon.
Helium is the second lightest element and the second most abundant element in the observable universe.
It is subjective to determine the most powerful element in the world, as each element has unique properties and uses. However, in terms of sheer destructive power, nuclear elements like uranium and plutonium are some of the most powerful due to their ability to release vast amounts of energy in nuclear reactions.
Strontium has chemical properties most like calcium as they belong to the same group (group 2) in the periodic table, known as the alkaline earth metals. They both share similar reactivity, solubility, and ability to form white precipitates with sulfate ions.
For example alkali metals because the differences of electronegativities are high.
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.
That would be the noble gases
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.
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.
