Periodic Trends

Front

What is the trend in ionic radius as you move down a group in the periodic table?

Back

Ionic radius increases as you move down a group due to the addition of electron shells.

Front

Which element has the highest electronegativity?

Back

Fluorine (F) has the highest electronegativity.

Front

What is electronegativity?

Back

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

Front

How does atomic radius change across a period from left to right?

Back

Atomic radius decreases from left to right across a period due to increasing nuclear charge.

Front

What is the relationship between atomic size and ionization energy?

Back

As atomic size decreases, ionization energy generally increases.

Front

Which group of elements is known for having low reactivity?

Back

Noble gases are known for having low reactivity.

Front

What is the trend in reactivity for alkali metals?

Back

Reactivity increases as you move down the group in alkali metals.

Front

Which element in Period 3 has the highest electronegativity?

Back

Chlorine (Cl) has the highest electronegativity in Period 3.

Front

What is the trend in metallic character as you move across a period?

Back

Metallic character decreases as you move from left to right across a period.

Front

What is the significance of the octet rule in relation to periodic trends?

Back

The octet rule explains the tendency of atoms to gain, lose, or share electrons to achieve a full outer shell.
