Periodic Trends

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 in Period 3 has the lowest electronegativity?

Back

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

Front

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

Back

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

Front

What trend occurs in electronegativity as you move down Group 16?

Back

Electronegativity decreases as you move down Group 16.

Front

What is the relationship between electronegativity and the ability to hold onto electrons?

Back

Atoms with high electronegativity hold onto their electrons more tightly.

Front

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

Back

Atomic size decreases as you move across a period due to an increase in the number of protons.

Front

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

Back

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

Front

How does the number of protons affect electronegativity?

Back

An increase in the number of protons generally leads to higher electronegativity.

Front

What is the significance of the periodic table in understanding trends like electronegativity?

Back

The periodic table organizes elements in a way that reveals trends in properties such as electronegativity, atomic size, and ionization energy.

Front

What is the general trend of electronegativity across a period from left to right?

Back

Electronegativity generally increases from left to right across a period.
