periodic table trends

Front

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

Back

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

Front

What is the trend in ionization energy as you move across a period from left to right?

Back

Ionization energy generally increases as you move from left to right across a period due to increasing nuclear charge.

Front

What are groups in the periodic table?

Back

Groups are vertical columns in the periodic table that contain elements with similar chemical properties.

Front

What are periods in the periodic table?

Back

Periods are horizontal rows in the periodic table that indicate the number of electron shells in the elements.

Front

What is the significance of the atomic number in the periodic table?

Back

The atomic number represents the number of protons in an atom and determines the element's identity.

Front

What is electronegativity?

Back

Electronegativity is a measure of an atom's ability to attract and hold onto electrons.

Front

How does electronegativity change across a period?

Back

Electronegativity increases as you move from left to right across a period.

Front

How does electronegativity change down a group?

Back

Electronegativity decreases as you move down a group in the periodic table.

Front

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

Back
