Periodic Trends and Atomic Properties

These flashcards cover key concepts related to atomic properties, periodic trends, and definitions relevant to the lecture on periodic table trends.

Atomic Radius

The size of an atom, typically increases down a group and decreases across a period.

Ionization Energy

The energy required to remove an outer shell electron from an atom.

Periodic Trends

Patterns observed in the properties of elements as you move across or down the periodic table.

Francium (Fr)

The largest atom on the periodic table.

Electron Shells

Regions surrounding the nucleus of an atom where electrons are likely to be found.

Metallic Character

The tendency of an element to exhibit properties of metals, such as electrical conductivity and malleability.

Nonmetals

Elements that typically lack metallic properties and are found on the right side of the periodic table.

Group 1 Elements

Elements like hydrogen, lithium, and sodium, where atomic size increases down the group.

Sodium vs Rubidium

Sodium has higher ionization energy than rubidium.
