Periodic Table Trends

Front

What is the Periodic Table?

Back

A tabular arrangement of chemical elements, organized by increasing atomic number, electron configuration, and recurring chemical properties.

Front

What are groups in the Periodic Table?

Back

Vertical columns in the Periodic Table that group elements with similar chemical properties.

Front

What are periods in the Periodic Table?

Back

Horizontal rows in the Periodic Table that indicate the number of electron shells in the elements.

Front

What is an alkali metal?

Back

Elements in Group 1 of the Periodic Table, known for being highly reactive, especially with water.

Front

What is a halogen?

Back

Elements in Group 17 of the Periodic Table, known for their reactivity and tendency to form salts with metals.

Front

What is a noble gas?

Back

Elements in Group 18 of the Periodic Table, known for their lack of reactivity due to having a full valence shell.

Front

What is atomic radius?

Back

The distance from the nucleus of an atom to the outermost shell of electrons, generally increasing down a group.

Front

Which element has the largest atomic radius in Group 1?

Back

Francium, as atomic radius increases down a group.

Front

What is ionization energy?

Back

The energy required to remove an electron from an atom in the gas phase, generally increasing across a period.

Front

What is electronegativity?

Back

A measure of the tendency of an atom to attract a bonding pair of electrons, generally increasing across a period.
