Periodic Trends Flashcard

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 is atomic radius?

Back

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

Front

How does atomic radius change 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 atom has the largest atomic radius: Magnesium (Mg), Sodium (Na), or Potassium (K)?

Back

Potassium (K) has the largest atomic radius among the three.

Front

Which has the smaller atomic radius: Rubidium (Rb) or Lithium (Li)?

Back

Lithium (Li) has a smaller atomic radius than Rubidium (Rb).

Front

What trend is observed in atomic radius across a period from left to right?

Back

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

Front

Which element has the largest atomic radius: Potassium (K), Rubidium (Rb), Francium (Fr), or Cesium (Cs)?

Back

Francium (Fr) has the largest atomic radius among these elements.

Front

What is the trend of electronegativity as you move across a period?

Back

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

Front

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

Back

Ionization energy decreases as you move down a group.
