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.
Elements in the same period has same number of valence shells.There are 7 periods in Periodic Table.
Elements 114, 116, and 118 are in period 7 of the periodic table, so they will have 7 outer level electrons. Each period in the periodic table represents the number of electron shells an atom has, and the elements in the same period will have the same number of outer level electrons.
There are 2 elements in the first period, 8, 8 elements in 2nd and 3rd periods respectively,
The horizontal rows of the periodic table are called Periods and the vertical rows are called groups.
The elements that have been removed from period 7 and placed below the periodic table are called the "lanthanides" and "actinides". These elements are also known as the "rare earth elements" and they are placed separately to conserve space on the periodic table.
Period 1: 2 elements Period 2: 8 elements Period 3: 8 elements Period 4: 18 elements Period 5: 18 elements Period 6: 32 elements Period 7: 25 elements
The f-block elements in period 7 are known as the actinides.
10 in period 410 in period 5 8 in period 6 8 in period 7 Total = 36
All elements comprising the period 7 in the periodic table are radioactive. In total this period has 32 elements.
Meitnerium is in the period 7 of the periodic table of elements.
The f-block elements in period 7 are known as the actinides.
8 elements
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.
There are 18 elements in period 4.
there are 32 elements in period 6.
