They have a full outer energy level ( full energy shell for GCSE and below ) which makes them completely unreactive* which is why they are called the noble gasses.
*Xe can actually react
Lead is in the group 14 of the Periodic Table.
The outer electron in the electronic configuration give idea of the group in the Modern Periodic Table & also period.
Pb is present in group-14. Its configuration is 6s2 , 6p2
A group in Periodic Table is the column of element in periodic table
In Periodic table , Group 18 corresponds to Nobel gas group. They are six elements in this group. Helium , Neon , Argon , Krypton , Xenon , Radon constitute these group. They are chemically inert elements and having stable configuration.
An element's electron configuration determines its location (group) in the periodic table. It tells us how many valence electrons (s and p sublevel).
Chlorine is in Group 17 of the Periodic Table.
Magnesium belongs to group-2. Its configuration is 2 8 2.
Yes, specifically the electron configuration. Members of the same group have the same number of valence electrons, but in increasing energy levels. As you move down the periodic table, the energy level increases. For example, all members of group 1 have an ns1 valence configuration, and all members of group 16 have an ns2np4 valence configuration. (n refers to the specific energy level.) This is important because it is the valence electrons that undergo chemical bonding.
Depending on the editor of the periodic table: name, symbol, atomic number, density, electron configuration, group, period, melting point, boiling point etc.
