Periodic Table

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 valence electrons?

Back

Electrons that are found in the outermost shell of an atom, crucial for determining how an element reacts chemically.

Front

What is the significance of a full valence shell?

Back

Atoms with a full valence shell are generally more stable and less reactive, as seen in noble gases.

Front

How are groups on the periodic table arranged?

Back

Groups are arranged vertically and contain elements with similar chemical properties.

Front

What family of elements is found on the far left of the periodic table?

Back

Alkali metals, which are highly reactive and have one valence electron.

Front

What is the atomic number?

Back

The number of protons in the nucleus of an atom, which determines the element's identity.

Front

What is the difference between atomic mass and atomic number?

Back

Atomic mass is the weighted average mass of an element's isotopes, while atomic number is the number of protons.

Front

What are noble gases?

Back

Elements in group 18 of the periodic table, known for their lack of reactivity due to having a full valence shell.

Front

What are transition metals?

Back

Elements found in groups 3-12 of the periodic table, known for their ability to form various oxidation states and colored compounds.

Front

What is the periodic law?

Back

The principle that the properties of elements are a periodic function of their atomic numbers.
