How to Identify It:The number for the element group is cited above the top element of each column. The element group values are integers running from 1 to 18. Examples:Hydrogen belongs to element group 1. Beryllium is the first element in group 2. Helium is the first element in group 18...
Indeed, in order to produce his periodic system, Mendeleev had to alter the atomic weights of some of the elements for which values had been assigned on the basis of chemical similarities (e.g. the atomic weight of beryllium had been fixed at three times its equivalent weight on the basis...
The number of protons in an atom is called the atomic number and it tells you what type of atom you have. An atomic number of 1 means the atom is hydrogen, atomic number 2 means helium, 3 means lithium, 4 is beryllium, and so on. The total number of protons and neutrons added ...
