2.1 Review Flashcard

Front

What is formed when atoms join together through a covalent bond?

Back

A molecule.

Front

How do Van der Waals forces compare to ionic and covalent bonds in terms of strength?

Back

Van der Waals forces are weaker than ionic and covalent bonds.

Front

What is the composition of a deuterium atom?

Back

A nucleus of one proton and one neutron, which is orbited by one electron.

Front

What can be said about the properties of sodium chloride compared to its constituent elements, sodium and chlorine?

Back

The properties of sodium chloride are very different from those of sodium and chlorine.

Front

What type of bond forms when electrons are shared between atoms?

Back

A covalent bond.

Front

What is the definition of a covalent bond?

Back

A covalent bond is a chemical bond that involves the sharing of electron pairs between atoms.

Front

What are ionic bonds?

Back

Ionic bonds are formed when one atom transfers electrons to another atom, resulting in the formation of charged ions that attract each other.

Front

What are the characteristics of Van der Waals forces?

Back

Van der Waals forces are weak attractions between molecules or parts of molecules that result from transient local partial charges.

Front

What is an isotope?

Back

An isotope is a variant of a chemical element that has the same number of protons but a different number of neutrons.

Front

How does the mass number of an atom relate to its isotopes?

Back

The mass number is the total number of protons and neutrons in the nucleus of an atom, which varies among isotopes of the same element.
