What are the general properties of the elements in the first two groups on the right side of the modern periodic table?
telo118 [61]
They have free electron(s) on their outermost energy levels making them good conductors.
They have metallic bonds in their chemical structure.
They readily lose the electrons on their outermost energy levels, to bond with non-metals in ionic bonds to form chemical compounds called "salts"

An ionic bond forms between atoms of​
Svetllana [295]
Ionic bonds form between nonmetals and metals.

The reason ionic bonds are formed is because nonmetals and metals usually have high electronegativities, which essentially means that metals pull on nonmetals' electrons.
When a metal takes an electron from a nonmetal, the metal becomes negatively charged and the nonmetal becomes positively charged. Because opposite charges attract, the two atoms will stick together, thus forming an ionic bond

What happens when a metal is reduced. Give an example of a metal being reduced
AlexFokin [52]

Answer:

The oxidation number of the metal decreases

2 Al  + Fe₂O₃ → Al₂O₃ + 2 FeO

The metal element iron, is reduced from Fe⁺³ in Fe₂O₃ to Fe⁺² in FeO

Explanation:

When an element gains electron, the element becomes reduced, hence when a metal is reduced, the metal gains electrons, which reduces the oxidation number of the metal

An example of a metal being reduced is;

2 Al  + Fe₂O₃ → Al₂O₃ + 2 FeO

In the above reaction, the iron (III) oxide is reduced to iron (II) oxide by aluminium metal.
