Al₂O₃

Front

What is the total number of electrons in the atom with the electron configuration 1s² 2s² 2p⁶?

Back

10

Front

Which of these is a covalent compound: NaCl, Pb(NO₃)₂, CO₂, AlCl₃?

Back

CO₂

Front

Define ionic bond.

Back

An ionic bond is a chemical bond formed through the electrostatic attraction between oppositely charged ions.

Front

What is a covalent bond?

Back

A covalent bond is a chemical bond formed when two atoms share one or more pairs of electrons.

Front

What is the octet rule?

Back

The octet rule states that atoms tend to form bonds in such a way that they have eight electrons in their valence shell, achieving a stable electron configuration.

Front

What is the difference between polar and nonpolar covalent bonds?

Back

Polar covalent bonds have unequal sharing of electrons, while nonpolar covalent bonds have equal sharing of electrons.

Front

What is a Lewis structure?

Back

A Lewis structure is a diagram that shows the bonding between atoms of a molecule and the lone pairs of electrons that may exist.
