Periodic Trends

Front

What is metallic character in elements?

Back

Metallic character refers to the level of reactivity of a metal. It increases down a group and decreases across a period from left to right.

Front

Which element has more metallic character, Barium (Ba) or Aluminum (Al)?

Back

Barium (Ba) has more metallic character than Aluminum (Al).

Front

What trend occurs in electronegativity as you move from left to right across a period?

Back

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

Front

How many valence electrons does Phosphorus (P) have?

Back

Phosphorus (P) has 5 valence electrons.

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 increased 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 has the largest atomic radius, Gallium (Ga) or Barium (Ba)?

Back

Barium (Ba) has a larger atomic radius than Gallium (Ga).

Front

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

Back

As the number of protons increases, the atomic size generally decreases due to increased nuclear attraction.

Front

Define electronegativity.

Back

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

Front

What is the general trend of ionization energy across a period?

Back

Ionization energy generally increases as you move from left to right across a period.
