Periodic Trends

Front

What is the periodic trend for 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 energy levels.

Front

What is the nucleus of an atom?

Back

The nucleus is the core of an atom where most of the mass exists, containing protons and neutrons.

Front

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

Back

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

Front

What happens to the size of atoms as you move from left to right across a period?

Back

Atomic size decreases from left to right across a period due to increased nuclear charge pulling electrons closer.

Front

What is electronegativity?

Back

Electronegativity is the ability of an atom to attract electrons in a chemical bond.

Front

Which element has a larger atomic radius: Strontium (Sr) or Zinc (Zn)?

Back

Strontium (Sr) has a larger atomic radius than Zinc (Zn).

Front

What is the trend in ionization energy as you move down a group?

Back

Ionization energy decreases as you move down a group due to increased distance of the outer electrons from the nucleus.

Front

What is the significance of the electron shell in an atom?

Back

Electron shells are regions around the nucleus where electrons are likely to be found, and they determine the atom's energy levels.

Front

Which element has the highest electronegativity?

Back

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

Front

What is the relationship between atomic size and the number of energy levels?

Back

As the number of energy levels increases, the atomic size increases.
