An electrically neutrall atom with atomic number of 7 implies an atom of NITROGEN.It is present on period 2 of the Periodic Table and if it is electrically neutrall it will have 2 electron shells,first shell will contain 2 electrons and the second one,5 electrons.Correspondingly in covalent bonding it shares 3 pairs of electrons,to attain its octet,resulting in the formation of a triple covalent bond.
IT has main energy level (principal quantum no) of 7 so it has 7 electron shells.
As the total number of elements discovered are 119 so 33 elements are present in this period and it is still incomplete.
1, nitrogen.
Unless there is an ion of a different element
32
Elements in the same period has same number of valence shells.There are 7 periods in Periodic Table.
Group 7 of the periodic table of Mendeleev and period 7 (transfermium elements).
There are 32 elements in the 6th period of the periodic table.

The f-block elements in period 7 are known as the actinides.
All elements comprising the period 7 in the periodic table are radioactive. In total this period has 32 elements.
10 in period 410 in period 5 8 in period 6 8 in period 7 Total = 36
Meitnerium is in the period 7 of the periodic table of elements.
A period is a row in the periodic table of elements.
8 elements
it does not neccicarely have a period, but if you needed one it would be the actinide series! Se it is not a number just the name of the series!
103
Berkelium is in the period 7 of the Mendeleev table of chemical elements and in the group of actinides.
Elements in the same period has same number of valence shells.There are 7 periods in Periodic Table.
They are in the period 7 and in the actinides family.
