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.

What does a period on the periodic table tell us?
Elements in the same period has same number of valence shells.There are 7 periods in Periodic Table.
Using the periodic table predict how many outer level electrons will be in elements 114 116 and 118?
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.
