Which of the following statements is true? A. Lithium will react to give up an electron however that electron can only be used to make an anion of a metal B. Lithium is most easily oxidized of the metals listed on the activity series and therefore it will most easily give electrons to metal cations C. Lithium is least easily oxidized of the metals listed on the activity series and therefore it is least likely to give electrons to metal cations D. Lithium will only react with metal ions that require the addition of one electron because of the fact that lithium only gives up one electron

The following statements are true:

Explanation:

When a neutral atom loses an electron then it forms a positive ion due to the decrease in number of electrons. This positive ion is also known as cation.

For example, atomic number of lithium is 3 and its electronic configuration is . It will attain stability by losing an electron.

Whereas when a neutral atom tends to gain electrons then it acquires a negative change and hence leads to the formation of a negative ion. This negative ion is also known as anion.

As the atomic size of lithium is very small as compared to other elements of its group. So, it is difficult to extract an electron from lithium atom hence, it is not easily oxidized.

Therefore, we can conclude that the following statements are true:

its weight is greatest on earth

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.
