Nitrogen. There are actually two periods classified as "5", more properly "V" (Roman numeral 5). VB, towards the left side of the Table, and VA, towards the right. In Group 2, there is no Period VB, only Period VA, which is nitrogen.
(I believe that it would be-) Radium (Ra) 88 (Group (up and down) 2A, and period (across) 7 would give you radium.)
beryllium is in group 2 and nitrogen is in group 5
If using the British system which has eight groups
Fluorine
Period two is first element in group 7
On the Periodic Table, rows are called periods and columns are called groups. If you go down two periods and over seven groups you will find the element Fluorine.
Radium (Ra, #88).
This chemical element is radium (Ra).
Magnesium
flourine

Tc The element is Technetium
The element is Technetium with the symbol, Tc.
there is no element found in such a place because that spot doesn't exist. there is a period 4-7 but not 1-3 for group 6. that particular spot is open and doesn't include any elements
there is no element found in such a place because that spot doesn't exist. there is a period 4-7 but not 1-3 for group 6. that particular spot is open and doesn't include any elements
There are only 7 groups. There are no more.

Group 7 Period 5
copper
Tc The element is Technetium
Nitrogen is the element with 7 protons. It is place din period -2 and group-15.
The element is Technetium with the symbol, Tc.
Group 7 of the periodic table of Mendeleev and period 7 (transfermium elements).
there is no element found in such a place because that spot doesn't exist. there is a period 4-7 but not 1-3 for group 6. that particular spot is open and doesn't include any elements

Radium (atomic no. 88): Group 2 (Alkaline Earth Metals), period 7 of the periodic table of elements.
Mn, Manganese
7th period because atomic size down the group increases. And Alkali Earth metals are found only in Group 1. The element is in Group 1 and period 7
