Periodic Trends and polarity recap

Front

What is electronegativity?

Back

Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons when the atom is in a compound.

Front

What type of molecule is CCl4?

Back

CCl4 is a nonpolar molecule.

Front

What region of the periodic table contains atoms that form covalent bonds?

Back

The right side of the periodic table contains atoms that form covalent bonds.

Front

Is F2 a polar or nonpolar molecule?

Back

F2 is a nonpolar molecule.

Front

Define a polar molecule.

Back

A polar molecule is a molecule that has a net dipole moment due to the presence of polar bonds, resulting in a partial positive charge on one end and a partial negative charge on the other.

Front

Define a nonpolar molecule.

Back

A nonpolar molecule is a molecule that does not have a net dipole moment, meaning the charges are evenly distributed.

Front

What is the difference between polar and nonpolar molecules?

Back

Polar molecules have an uneven distribution of charge, while nonpolar molecules have an even distribution of charge.

Front

What is the significance of molecular polarity in chemistry?

Back

Molecular polarity affects physical properties such as boiling point, melting point, and solubility.

Front

What is the trend of electronegativity in the periodic table?

Back

Electronegativity increases from left to right across a period and decreases from top to bottom within a group.

Front

What is ionization energy?

Back

Ionization energy is the energy required to remove an electron from an atom in its gaseous state.
