"Pb" Lead, its atomic number is 82 and the mass number is 207.2, as it has six electronic shells therefore it is placed in the sixth period of the Periodic Table and as it has 4 electrons in it's outer most shell therefore it is placed in group number four of the periodic table.
The element with 4 electron shells and 1 electron in the outer shell is potassium (K).
The element that has 4 electron shells and 8 outside electrons is Krypton. The K, L, M and N shells have 2, 8, 18 and 8 electrons respectively.
All elements in group 14 each have 4 valance electrons, which are the electrons in its outer most energy level.
What element has only 1 electron in its outermost shell, but has 4 shells.
Carbon, Silicon, Germanium, Tin and Lead
Oxygen
Tellurium

The element with 6 outer shell electrons is carbon. Carbon has 4 electrons in its outer shell and 2 electrons in the shell before that, totaling 6 outer shell electrons.
If an element is chemically active, its outer electron shell is not completely filled. This makes the element more likely to form bonds with other atoms in order to achieve a more stable electron configuration.
Chromium has two electrons in the outer most shell.
Antimony has 5 valence electrons.
Beryllium has one outer electron shell with two electrons.
The outer electron shells of halogens have seven electrons, making them one electron short of a full outer shell. This makes halogens highly reactive as they tend to gain an electron to achieve a stable electron configuration. Halogens are located in Group 17 of the periodic table.
Period number = no. of electron shells. Therefore neon has two shells.
If an element is chemically active, its outer electron shell is not completely filled. This makes the element more likely to form bonds with other atoms in order to achieve a more stable electron configuration.
The element with 6 outer shell electrons is carbon. Carbon has 4 electrons in its outer shell and 2 electrons in the shell before that, totaling 6 outer shell electrons.
Elements in Group 1 of the periodic table have one electron in their outer shell, while elements in Group 2 have two electrons in their outer shell. This configuration makes these elements more stable and likely to form ions with a positive charge by losing these outer electrons to achieve a full outer shell.
Chromium has two electrons in the outer most shell.
The calcium atom has 2 outer shell electrons. It's configuration is: [Ar] 4s2 it also has 2 inner shell electrons
Francium has 1 electron in its outermost shell. Francium is in group 1 of the periodic table, so it has 1 electron in its outermost shell, making it highly reactive.
Berkelium has 97 electrons, which means it has 7 electron shells.
Some elements are highly reactive because their outermost energy levels are only partially filled, and they seek to gain or lose electrons to achieve a stable electron configuration. This can lead to the formation of chemical bonds with other elements in order to reach a more stable state.
Californium has seven electron shells ; the outer shell has two electrons.
This is an ionic bond.
