The most common element in Earth's first atmosphere was likely hydrogen, along with helium and traces of other elements. These gases were likely present during the planet's formation and early evolution.
Sodium (Na) is the element that would most likely form an ionic compound with fluorine (F). Sodium readily gives up an electron to fluorine to achieve a stable electron configuration, forming sodium fluoride (NaF) which is an ionic compound.
Element A and element B are the most likely to have similar properties because they belong in the same family, because if you know an element's family you can tell the number of valance electrons and the elements they react with. In periods, the properties are not alike, they slowly change in a pattern.
The dearest element is likely astatine due to its rarity and high production cost, making it one of the most expensive elements to produce and acquire.

Potassium is the element that is most easily reduced because it has a low ionization energy and readily loses an electron to form a +1 cation.
A new element is most likely metal because it gives people the most boners
There will most likely be more wildlife in that area.
Someone would most likely receive a shock through the element of electricity.
Answer this question… Fe3+
Chlorine is the element most likely to react with aluminum, forming aluminum chloride through a chemical reaction.
Arsenic.
Chlorine is the most reactive gas element. Chlorine is in the halogen family.
Reduction potential indicates an element's tendency to gain electrons and undergo reduction. Elements with higher reduction potentials are more likely to be reduced and are considered more stable in their reduced form, while elements with lower reduction potentials are less stable and more likely to be oxidize or lose electrons.
