The Periodic Table of the Elements, in Pictures and Words
Alkali Earth Metals are reactive and readily form compounds but are not found free in nature. Their oxides are called alkali earths. In pure form, they are soft and somewhat brittle metals. elements.wlonk.com Solid The color of the symbol is Solid The color of the symbol is the color of the element in the color of the element in The Periodic Table Liquid its most common pure form.

Normally, an atom Magnetic Magnetic ferromagnetic at room temperature ferromagnetic at room temperature has equal numbers of protons and electrons. An ion is a charged atom with more or fewer electrons than Noble Metals Noble Metals protons. corrosion-resistant corrosion-resistant The atomic weight of an element is the average number Radioactive Radioactive of protons plus neutrons. You can easily estimate the all isotopes are radioactive all isotopes are radioactive atomic weight: it is usually 2 to 2.5 times the atomic number.
