주요 개념

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Ionic Bonding

Ionic bonding occurs when one atom donates one or more electrons to another atom, resulting in the formation of charged ions. Typically, this involves a metal atom losing electrons to become a positively charged cation, while a nonmetal atom gains those electrons to become a negatively charged anion. The electrostatic attraction between these oppositely charged ions creates a strong bond, characteristic of ionic compounds.

Covalent Bonding

Covalent bonding involves the sharing of electron pairs between atoms, usually between nonmetals. In this type of bond, atoms achieve stability by sharing electrons, which allows them to fill their outer electron shells. Covalent bonds can be single, double, or triple, depending on the number of shared electron pairs, and they can vary in polarity based on the electronegativity of the bonded atoms.

Nonpolar Covalent Bonding

Nonpolar covalent bonding occurs when two identical nonmetal atoms share electrons equally, resulting in no charge separation. This type of bond typically forms between atoms with similar electronegativities, such as in diatomic molecules like O2 or N2. Because the electron distribution is symmetrical, nonpolar covalent bonds do not create dipoles, making these molecules generally nonpolar in nature.

The following ball-and-stick molecular model is a representation of thalidomide, a drug that causes birth defects when taken by expectant mothers but is valuable for its use against leprosy. The lines indicate only the connections between atoms, not whether the bonds are single, double, or triple. (Red = O, gray = C, blue = N, ivory = H). Give the formula of thalidomide, and indicate the positions of multiple bonds and lone pairs.
