"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.
What else can I help you with?
What element has 6 outer shell electrons?
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 what is the state of its outer electron shell?
The key to "happiness" for an atom is a full outer electron shell. (The outer electron shell is called the valence shell.) There are two conditions that cause a shell not to be full. Either it has only an electron or two (or three) in the outer electron shell or it's short an electron or two in that outer shell. The direct answer to the question is that if an element is chemically active, its outer electron shell is incomplete or is not full.
How many electron shells does chromium have?
Chromium has two electrons in the outer most shell.
How many electrons does it have in its outer shell?
Antimony has 5 valence electrons.
How many outer shells does beryllium have?
Beryllium has one outer electron shell with two electrons.
How many valence shells does the element neon have?
Period number = no. of electron shells. Therefore neon has two shells.
What element has 6 outer shell electrons?
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.
What is the characteristics about the outer electron shells of halogens?
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.

What is the outer energy level of californium?
Californium has seven electron shells ; the outer shell has two electrons.
When an electron moves from the outer shell of one element to the outer shell of another element what kind of bond has been created?
This is an ionic bond.
How many shells does berkelium have?
Berkelium has 97 electrons, which means it has 7 electron shells.
What is The element that has no unpaired electrons in the outer shell in its ground state is?
There are many elements which have no unpaired electrons in their outer shells. The Noble gasses all have closed shells of valence electrons. The alkali earth metals (Beryllium, Magnesium, Calcium etc) also have no unpaired electrons, although their outer shell is not entirely full.
