There are four electrons found on the outer shell of a atomic structure of tin. They are in a group of four.
The atomic structure of elements in the same family are similar in that all have the same number of valence electrons in their outer shell. For example, the Noble Gases all have 8 electrons in their outer shell.
The atomic number for hydrogen (H) is 1, and it has 1 electron in the outer shell.
Chlorine is a chemical element with the symbol Cl and an atomic number of 17. It has 7 electrons in its outer shell.
Chlorine is in period three because that is how many outer shells it has. One period is one shell... In the First outer shell you can only hold.. 2 electrons. Second outer shell can hold 10 electrons. Third outer shell can hold 18 electron. Protons + Electrons = Atomic Number Atomic Number - Atomic Mass = Number of Neutrons in Outer Shells
Nitrogen has atomic number = 7. The outer shell has 5 electrons, it requires 3 more electrons to complete the outer energy shell.
Its atomic number is 7, and so it needs a further 3 electrons to fill its outer shell.
Atoms will gain, lose, or share electrons to match the number of outer shell electrons of a noble gas.
Elements in the same group have the same number of valence electrons. These are the outer-shell electrons that react with other elements.
The atomic properties depends on the electrons of the outer shell. THe elements in differnent periods have the same arrangments of electrons in the outer shell. Thus, atomic prperties vary in a similar way in diffrent periods

The name most often given to the outermost shell of electrons in the context of atomic structure is the valence shell.
Chlorine has 17 electrons, distributed in the following way: 2 in first shell 8 in second shell 7 in third (outer) shell Therefore Chlorine has 7 electrons in its outer shell.
