Chem in the Earth System IS3T1: Periodic Trends

Front

What is electronegativity?

Back

Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons. It is a key factor in determining how atoms interact in chemical bonds.

Front

Which element has a higher electronegativity than arsenic (As)?

Back

Carbon (C) has a higher electronegativity than arsenic (As).

Front

What are the vertical columns in the Periodic Table called?

Back

The vertical columns in the Periodic Table are called groups.

Front

What is the relationship between elements in the same group?

Back

Elements in the same group have similar physical and chemical properties due to having the same number of valence electrons.

Front

Which element has a higher ionization energy than arsenic (As)?

Back

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

Front

What is 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 electronegativity across a period in the Periodic Table?

Back

Electronegativity generally increases across a period from left to right due to increasing nuclear charge.

Front

What is the trend of ionization energy down a group in the Periodic Table?

Back

Ionization energy generally decreases down a group due to increased distance between the nucleus and the outermost electrons.

Front

What is a period in the context of the Periodic Table?

Back

A period is a horizontal row in the Periodic Table, indicating elements with the same number of electron shells.

Front

What is the significance of noble gases in the Periodic Table?

Back

Noble gases are located in Group 18 and are characterized by having a full valence shell, making them very stable and unreactive.
