Somealkali metalshave been known and put to good use long before Mendeleev created the periodic table. For instance, the Old Testament mentions salt – a combination of the alkali metal sodium with chlorine – 31 times. The New Testament refers to it 10 times and calls sodium carbonate "neter...

For instance, in exploring patterns in the periodic table, students may know from real-world experience that silver, gold and copper are all metals. But when asked to talk about what properties these three metals share, students may focus directly on the symbolic language, citing for instance ...
Atoms are the fundamental constituents of all elements found in the periodic table. Each element consists of a unique type of atom, characterized by its atomic number. For example, hydrogen atoms form the element hydrogen (H), oxygen atoms make up oxygen (O), and so on. Elements can exist...
The stability of the noble gases is what all the elements want to achieve. These elements make up the last column or group of the periodic table. They all have full valence shells or eight electrons. Helium only has two, but it is still full....
