Gethin: And today we're going to be looking at the periodic table. Let's take a look at some Group 1 metals then - also known as alkaline metals. Fran: Group 1 elements are called the alkali metals.

Alkali metals: Alkali metals have a single electron in their outermost energy level, so they bond readily with other elements. They are typically soft enough to slice with a knife and are good ...

The periodic table of elements—also known as Mendeleev’s table—was developed in 1869 by Russian chemist Dmitri Mendeleev. It organizes all known chemical elements by their atomic number ...

The periodic table of chemical elements, often called the periodic table, organizes all discovered chemical elements in rows (called periods) and columns (called groups) according to increasing atomic ...

These rules help in identifying and writing chemical symbols consistently across all elements. The symbol serves as a shorthand notation for each element's name in formulas and equations, making ...

The Periodic Table, first compiled by Russian chemist Dmitri Mendeleyev, is organized by the number of protons in the nucleus of each element's atom, known as the atomic number. The elements are ...
