Periodic Trends

Front

What is electronegativity?

Back

Electronegativity is how good an atom is at attracting electrons.

Front

Which element has a higher ionization energy than arsenic (As)?

Back

Neon (Ne) has a higher ionization energy than arsenic (As).

Front

What happens to electronegativity as you move down group 16 in the periodic table?

Back

The electronegativity of each successive element decreases.

Front

Why do atoms get bigger as you move down the periodic table?

Back

Atoms get bigger because they have more energy levels.

Front

What is the term for the energy required to remove an electron from gaseous atoms?

Back

Ionization energy is the energy required to remove an electron from gaseous atoms.

Front

What is the trend of ionization energy across a period in the periodic table?

Back

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

Front

What is the trend of atomic radius down a group in the periodic table?

Back

The atomic radius generally increases down a group.

Front

What is the relationship between electronegativity and ionization energy?

Back

Generally, as electronegativity increases, ionization energy also increases.

Front

What is the definition of atomic radius?

Back

Atomic radius is the distance from the nucleus to the outermost electron shell.

Front

What is the trend of metallic character across a period?

Back

Metallic character decreases across a period from left to right.
