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 concept in understanding chemical bonding and reactivity.

Front

Which element has a higher electronegativity: Carbon (C) or Arsenic (As)?

Back

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

Front

What is the trend of electronegativity across a period in the periodic table?

Back

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

Front

What is the trend of electronegativity down a group in the periodic table?

Back

Electronegativity decreases down a group due to increased distance between the nucleus and the valence electrons.

Front

Which element has the highest electronegativity?

Back

Fluorine (F) has the highest electronegativity of all elements.

Front

What is ionization energy?

Back

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

Front

How does ionization energy change across a period?

Back

Ionization energy increases across a period from left to right.

Front

How does ionization energy change down a group?

Back

Ionization energy decreases down a group due to increased atomic size and shielding effect.

Front

Which element has the lowest ionization energy in Period 3?

Back

Sodium (Na) has the lowest ionization energy in Period 3.

Front

What is the relationship between electronegativity and ionization energy?

Back

Generally, elements with high electronegativity also have high ionization energy.
