Semester 1 Chemistry Final review

Front

What is electronegativity?

Back

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

Front

What happens to electronegativity across a period in the periodic table?

Back

Electronegativity increases from left to right across a period.

Front

What happens to electronegativity down a group in the periodic table?

Back

Electronegativity decreases down a group.

Front

Define ionization energy.

Back

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

Front

What is the trend of ionization energy in the periodic table?

Back

Ionization energy increases from left to right and decreases from top to bottom.

Front

What is the atomic mass of Fluorine (F)?

Back

The atomic mass of Fluorine (F) is 19.

Front

What is an ionic bond?

Back

An ionic bond is formed through the transfer of electrons from one atom to another.

Front

What is the formula for Lead Chloride?

Back

The formula for Lead Chloride is PbCl2.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons, while covalent bonds involve the sharing of electrons.

Front

What are the characteristics of ionic compounds?

Back

Ionic compounds typically have high melting and boiling points, are soluble in water, and conduct electricity when dissolved.
