Ionic And Covalent Bonding Flashcards
What type of bond is formed when electrons are transferred from one atom to another?
Ionic bond
True or False: Covalent bonds involve the sharing of electron pairs between atoms.
True
Fill in the blank: In ionic bonding, the resulting charged particles are called __________.
ions
What is the primary characteristic of ionic compounds?
They form crystalline structures and have high melting and boiling points.
Which type of bond typically occurs between metals and nonmetals?
Ionic bond
True or False: Covalent bonds can form between two nonmetals.
True
Which of the following is an example of an ionic compound? A) H2O B) NaCl C) CO2
B) NaCl
What is the shape of molecules formed by covalent bonds?
Varies depending on the number of bonds and lone pairs (e.g., linear, bent, tetrahedral).
Fill in the blank: The bond formed by the electrostatic attraction between oppositely charged ions is called __________.
ionic bond
What is the primary force holding ionic compounds together?
Electrostatic forces between ions.
True or False: Ionic compounds are generally soluble in water.
True
What are valence electrons?
Electrons in the outermost shell of an atom that are involved in bonding.
Which type of bond is typically stronger, ionic or covalent?
Covalent bonds are generally stronger than ionic bonds.
What is the result of an ionic bond between sodium (Na) and chlorine (Cl)?
Formation of sodium chloride (NaCl).
Fill in the blank: The ability of an atom to attract electrons in a bond is called __________.
electronegativity
What type of bond is formed in molecules like O2 and N2?
Covalent bond
Which of the following is NOT a property of ionic compounds? A) High melting point B) Conduct electricity in solid state C) Brittle
B) Conduct electricity in solid state
True or False: Ionic bonds are formed through the sharing of electrons.
False
What happens to the electrons in a metallic bond?
They are delocalized and free to move throughout the metal structure.
Which type of bond typically has lower melting and boiling points, ionic or covalent?
Covalent bonds
