The periodic table is a tabular arrangement of chemical elements, organized by increasing atomic number, electron configuration, and recurring chemical properties.
A table showing the life expectancy of different species.
It is a chart used to measure temperature variations.
A tool for tracking historical events.
A method to analyze crystal lattice structures.
A horizontal row of chemical elements in the periodic table.
A group is a vertical column in the periodic table, and elements in the same group typically share similar chemical properties.
A classification of elements based on isotopic composition.
The time it takes for a radioactive element to decay by half.
A period is a horizontal row in the periodic table. Elements in the same period have the same number of atomic orbitals.
Any set of elements classified by similar densities.
A vertical set of elements with similar reactivity.
Alkali Metals, Lanthanides, Actinides.
Metalloids, Halogens, Alkaline Earth Metals.
The three main categories are metals, non-metals, and noble gases.
Heavy Metals, Light Metals, Reactive Gases.
Transition metals are found in periods 6-7 and are known for their radioactivity.
Elements located at the ends of the periodic table with stable electron configurations.
Transition metals are elements located in groups 3-12 of the periodic table and are known for their ability to form variable oxidation states.
Elements located in group 1 and known for high reactivity with water.
