Semester 1 Final Review

Front

What is ionization energy?

Back

The amount of energy required to remove an electron from an atom.

Front

Which element has the highest ionization energy among F, Cl, Br, and Cs?

Back

Fluorine (F) has the highest ionization energy.

Front

What is the basis of a metallic bond?

Back

The attraction between positive metal ions and free floating electrons.

Front

How many valence electrons do noble gases have, excluding Helium?

Back

Noble gases have 8 valence electrons.

Front

What is a general chemical characteristic of metals?

Back

Metals tend to lose electrons.

Front

Define electron affinity.

Back

The amount of energy released when an electron is added to a neutral atom.

Front

What is the atomic radius?

Back

The distance from the nucleus of an atom to the outermost shell of electrons.

Front

What is effective nuclear charge?

Back

The net positive charge experienced by an electron in a multi-electron atom.

Front

Explain the trend of ionization energy across a period in the periodic table.

Back

Ionization energy generally increases across a period due to increasing nuclear charge.

Front

Explain the trend of atomic radius down a group in the periodic table.

Back

Atomic radius generally increases down a group due to the addition of electron shells.
