Which type of bond is formed when atoms share electrons?
In a covalent bond, atoms share pairs of electrons to achieve a full outer shell and gain stability.
What type of bond is created when one atom donates an electron to another atom?
An ionic bond forms when one atom transfers an electron to another atom, resulting in oppositely charged ions that attract each other.
What type of bond involves the electrostatic attraction between delocalized electrons and positively charged metal ions?
Metallic bonds involve the attraction between free-floating valence electrons and the positively charged metal ions, giving metals their characteristic properties.
Which of the following molecules is held together by a polar covalent bond?
In a water molecule (Hâ‚‚O), the electrons are shared unequally between oxygen and hydrogen atoms, creating a polar covalent bond with partial charges.
Which of the following best describes a hydrogen bond?
A hydrogen bond is a weak interaction that occurs between a hydrogen atom bonded to a highly electronegative atom (such as oxygen, nitrogen, or fluorine) in one molecule and an electronegative atom in another molecule.
