Building Molecules

What is chemical bonding?

• The process of separating atoms to form molecules or compounds

• The process of converting molecules into atoms

• The process of rearranging atoms within a molecule

• The process by which atoms are held together to form molecules or compounds.

Name the two main types of chemical bonding.

• Metallic bonding and hydrogen bonding

• Polar bonding and nonpolar bonding

• Single bonding and double bonding

• Ionic bonding and covalent bonding

What is an ionic bond?

• A bond that results from the transfer of protons between atoms

• A chemical bond that involves the electrostatic attraction between oppositely charged ions.

• A bond that involves the attraction between two nonpolar molecules

• A bond formed by sharing electrons between atoms

What is a covalent bond?

• Sharing of neutron pairs between atoms

• Exchange of proton pairs between atoms

• Sharing of electron pairs between atoms

• Attraction of opposite charged ions

How do atoms form ionic bonds?

• By releasing neutrons from the nucleus

• By transferring electrons from one atom to another

• By sharing protons between atoms

• By absorbing photons from the environment

How do atoms form covalent bonds?

• Exchanging positrons with each other

• Absorbing neutrons from each other

• Donating protons to each other

• Sharing pairs of electrons between each other

What is a molecule?

• A group of two or more atoms held together by chemical bonds.

• A type of plant species

• A unit of measurement for weight

• A type of rock formation

Give an example of a molecule.

• Salt (NaCl)

• Carbon dioxide (CO2)

• Water (H2O)

• Oxygen (O2)

Explain how molecules are formed.

• Atoms bond together to form molecules.

• Molecules are formed by heating up atoms until they combine.

• Molecules are formed by breaking down larger particles into smaller ones.

• Molecules are formed by mixing different types of liquids together.

Why is understanding chemical bonding important in building molecules?

• To make molecules look pretty

• To impress other scientists

• To waste time and resources

• To predict the behavior and properties of molecules
