Periodic Trends and Classification

Front

What is electronegativity?

Back

Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons.

Front

Which element has a higher electronegativity: Nitrogen (N) or Carbon (C)?

Back

Nitrogen (N) has a higher electronegativity than Carbon (C).

Front

What happens to atomic size as you move across a period in the periodic table?

Back

Atomic size decreases as you move from left to right across a period due to increasing nuclear charge.

Front

What is the trend 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

Which element in Period 3 has the lowest electronegativity?

Back

Sodium (Na) has the lowest electronegativity in Period 3.

Front

What is the atomic radius of Francium compared to other alkali metals?

Back

Francium has the largest atomic radius among alkali metals.

Front

Which element has a larger atomic radius: Strontium or Zinc?

Back

Strontium has a larger atomic radius than Zinc.

Front

What is the relationship between the number of protons and atomic size across a period?

Back

As the number of protons increases across a period, the atomic size decreases.

Front

Define atomic radius.

Back

Atomic radius is the distance from the nucleus of an atom to the outermost shell of electrons.

Front

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

Back

Electronegativity generally decreases as you move down a group.
