Periodic Table, Configuration, Trends

Front

What is the Periodic Table?

Back

A chart that organizes all known elements based on their atomic number, electron configuration, and recurring chemical properties.

Front

What are valence electrons?

Back

Electrons in the outermost shell of an atom that determine its chemical properties and reactivity.

Front

What happens to atomic radius as you move down a group in the Periodic Table?

Back

Atomic radius increases because you add more and more shells (energy levels).

Front

What is ionization energy?

Back

The energy required to remove an electron from an atom.

Front

Which element has the smallest ionization energy: Na, P, or S?

Back

Na (Sodium) has the smallest ionization energy.

Front

What charge does an atom have if it gains one electron?

Back

The atom has a charge of -1.

Front

What is the charge of an atom that loses two electrons?

Back

The atom has a charge of +2.

Front

Which of the following is a metal: Li, Si, or S?

Back

Li (Lithium) is a metal.

Front

What is the trend in ionization energy across a period?

Back

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

Front

What is the trend in electronegativity down a group?

Back

Electronegativity generally decreases as you move down a group.
