covalent and ionic bonding

What is a covalent bond?

• A type of bond where atoms transfer electrons.

• A type of bond where two atoms share one or more pairs of electrons.

• A bond that occurs between metal and non-metal atoms.

• A bond that involves the attraction between charged ions.

What type of bond is formed in ammonium (NH4)?

• Ionic bond

• Covalent bond

• Metallic bond

• Hydrogen bond

Which subatomic particle is primarily responsible for bonding?

• Protons

• Neutrons

• Electrons

• Photons

What is an example of an ionic compound?

• Sodium chloride (NaCl)

• Calcium carbonate (CaCO3)

• Glucose (C6H12O6)

• Iron(III) oxide (Fe2O3)

Can covalent bonds form between two nonmetals?

• Yes, covalent bonds typically form between two nonmetals.

• No, covalent bonds can only form between metals.

• Covalent bonds do not exist between nonmetals.

• Covalent bonds can only form in ionic compounds.

What type of bond is formed between potassium and chlorine in potassium chloride?

• Covalent bond

• Metallic bond

• Ionic bond

• Hydrogen bond

What is the charge of an ion formed by gaining an electron?

• The ion will have a positive charge.

• The ion will have a neutral charge.

• The ion will have a negative charge.

• The ion will have a variable charge.

What happens to electrons in an ionic bond?

• Electrons are shared between atoms.

• Electrons are lost by both atoms.

• Electrons are transferred from one atom to another.

• Electrons remain stationary and do not move.

What is an example of a covalent compound?

• Water (H2O)

• Sodium Chloride (NaCl)

• Calcium Oxide (CaO)

• Iron (Fe)

What is an ionic bond?

• A type of bond formed by sharing electrons between atoms.

• A type of chemical bond formed through the electrostatic attraction between oppositely charged ions.

• A bond that occurs only in metals.

• A weak interaction between molecules.
