Why do covalent compounds share electrons?

This video tutorial explains how to identify covalent compounds, which form when electrons are shared between two nonmetals or anions. The video covers the role of electronegativity in electron sharing, criteria for identifying covalent compounds, and provides examples, including the exception of hydrogen. The tutorial emphasizes that nonmetals are located on the right side of the periodic table and have similar electronegativity, leading to electron sharing rather than electron transfer.

What is a key characteristic of covalent compounds?

• They are formed by the gain of electrons.

• They are formed by the transfer of electrons.

• They are formed by the sharing of electrons.

• They are formed by the loss of electrons.

Why do nonmetals share electrons in covalent compounds?

• Because they have a small difference in electronegativity.

• Because they have a large difference in electronegativity.

• Because they have no electronegativity.

• Because they have the same electronegativity.

Which of the following is true about nonmetals in covalent bonding?

• They are located on the left side of the periodic table.

• They are not found on the periodic table.

• They are located on the right side of the periodic table.

• They are located in the middle of the periodic table.

Which element is an exception to the location rule for nonmetals?

• Hydrogen

• Carbon

• Nitrogen

• Oxygen

What type of charge do nonmetals typically have?

• Neutral

• Positive

• Variable

• Negative
