Rethink 17. In general, only the outside shell electrons are involved in forming bonds.

All the others are correct?

11. The statement "Semiconductors (metalloids) have properties of both metals and nonmetals" is true. To confirm this, you can research and study the properties of semiconductors. Semiconductors are elements that have properties in between those of metals and nonmetals. They can conduct electricity under certain conditions like metals, but they can also act as insulators under other conditions like nonmetals.

13. The statement "Covalent bonding occurs when electrons are transferred from one atom to another" is false. Covalent bonding is a type of chemical bonding where electrons are shared between atoms, rather than being transferred. In covalent bonds, atoms share electrons in order to fill their outermost energy levels and achieve stability.

17. The statement "Bonding involves all the electrons in an atom" is true. When two or more atoms come together to form a chemical bond, the bonding involves the interactions of the electrons in their outermost energy levels. These electrons play a crucial role in determining the type and strength of the bond formed between the atoms.

20. The statement "Nonpolar bonds form when electrons are shared unevenly" is false. Nonpolar bonds form when electrons are shared equally between atoms, resulting in a balanced distribution of charge. In polar bonds, on the other hand, electrons are shared unequally, creating partial positive and partial negative charges on the atoms involved.
