 Which of the following statements about the chemical properties of Group 13 elements is true?

Option: 1

They tend to form covalent bonds with nonmetals


Option: 2

They exhibit an oxidation state of -3 in their compounds


Option: 3

They are generally unreactive with other elements

 


Option: 4

They have high electron affinities

Group 13 elements have three valence electrons in their outermost shell, which makes them more likely to form covalent bonds with nonmetals. This is because they can share these electrons with other elements to achieve a stable octet configuration. Group 13 elements allow them to form strong covalent bonds with smaller nonmetal atoms. Therefore, option (1) is correct.

Option (2) is incorrect because Group 13 elements can exhibit oxidation states of +3 or +1 in their compounds, but not -3.

Option (3) is also incorrect because Group 13 elements are generally reactive with other elements.

Finally, option (4) is incorrect because Group 13 elements have relatively low electron affinities and do not easily accept additional electrons.
