A student studies three different substances. Substance X forms when one atom transfers electrons completely to another atom forming oppositely charged ions. Substance Y forms when two atoms share electrons between their nuclei. Substance Z consists of positive metal ions surrounded by a mobile cloud of electrons. Based on this information, which option correctly identifies the bonding present in these substances?

In ionic compounds, the force holding the particles together arises due to the electrostatic attraction between oppositely charged ions formed after electron transfer, whereas in covalent compounds the bonding force results from the attraction between shared electrons and the nuclei of bonded atoms. Which conclusion correctly describes this difference?

A chemistry teacher explains that metallic bonding occurs in metals where valence electrons are not attached to a particular atom but move freely throughout the metal lattice. The attraction between this mobile electron cloud and positive metal ions keeps the structure intact. What is this type of attraction called?

When sodium reacts with chlorine, sodium transfers one electron to chlorine forming Na⁺ and Cl⁻ ions. The strong attraction between these oppositely charged ions forms a stable crystal lattice. Which type of bonding is responsible for holding the ions together?

Two hydrogen atoms combine to form a hydrogen molecule by sharing a pair of electrons between their nuclei. The bond formed results from the electrostatic attraction between the shared electrons and the two nuclei. What type of bond is present in this molecule?

Which of the following statements best distinguishes metallic bonding from ionic bonding in terms of electron behavior?

A compound shows strong attraction between ions arranged in a crystal lattice structure due to electrostatic forces between cations and anions. Which property is most directly related to this type of bonding?

In a metallic structure, atoms lose their valence electrons which become delocalized and move freely throughout the metal lattice. What role do these delocalized electrons play?

Which statement correctly compares the forces responsible for bonding in ionic and covalent compounds?

A metal wire can be bent without breaking because metal atoms are held together by the attraction between positive metal ions and a sea of mobile electrons. Which bonding model explains this property?

Which of the following descriptions best represents the structure of a typical ionic compound?

A scientist observes that electrons in a substance are free to move throughout the structure rather than remaining associated with specific atoms. Which bonding type is most consistent with this observation?

Which of the following situations best represents the formation of a covalent bond?

In metallic bonding, metal atoms contribute their valence electrons to a common electron cloud that surrounds all metal cations in the lattice. What is the main force holding the structure together?

Which comparison correctly summarizes the nature of bonding forces in ionic, covalent, and metallic substances?
