Periodic Table and Trends Review

Front

What is the periodic table?

Back

A tabular arrangement of chemical elements, organized by increasing atomic number, electron configuration, and recurring chemical properties.

Front

What is ionization energy?

Back

The energy required to remove an electron from an atom in its gaseous state.

Front

Which element has a higher ionization energy: Neon (Ne) or Arsenic (As)?

Back

Neon (Ne) has a higher ionization energy than Arsenic (As).

Front

What trend is observed in atomic radius as you move down a group in the periodic table?

Back

Atomic radius increases as you move down a group due to the addition of electron shells.

Front

What trend is observed in atomic radius as you move across a period from left to right?

Back

Atomic radius decreases as you move across a period due to increased nuclear charge pulling electrons closer.

Front

What are halogens?

Back

Halogens are a group of elements in Group 17 of the periodic table, known for their reactivity and tendency to form salts.

Front

Which element has a smaller atomic radius: Potassium (K) or Bromine (Br)?

Back

Bromine (Br) has a smaller atomic radius than Potassium (K).

Front

What is the significance of protons in determining atomic size?

Back

As the number of protons increases, the positive charge of the nucleus attracts electrons more strongly, resulting in a smaller atomic size.

Front

What is the general trend of electronegativity across a period?

Back

Electronegativity increases across a period from left to right.

Front

What is the general trend of electronegativity down a group?

Back

Electronegativity decreases down a group.
