These are the atomic numbers of chemical elements.
They have different numbers of valence electrons.
The group is the column and the period is the row. Group numbers run across the top of the periodic table, and period numbers run down the left side. Group tells you the number of valence electrons and period tells you the energy level that those valence electrons are in.
I (if you count the rows) is at the 7th row, so it has 7 valence electrons. The is the same for Br, so there is a total of 14 electrons. :)
a horizontal row is called a period.a vertical row is called a group
Numbers in a row that are even, such as: 2,4,6,8,10,12,14,16,18,20,22,24,26 , etc.
The numbers start with one and increase for each subsequent row.
If you consider row 0 as the row consisting of the single 1, then row 100 has 6 odd numbers.

A row could be a row of cells within a spreadsheet. Rows are identified by numbers e.g. Row 1, Row 2 etc. Sometimes when you use databases and you look at records entered in table view, one record in the database e.g. a record about a particular person is commonly referred to as a row.
Yes. For example, the mean of: 10,20,20,20,20,30 is (10+20+20+20+20+30)/6
If the row numbers are not consecutive then there are hidden rows.
Serial numbers. Or, generically for any spreadsheet, row headers.
it mean you row your boat with oars
Consecutive numbers have a GCF of 1.
there are 15 numbers in the heading of bingo
