Trying to quantify the highest number of anything in mathematics is often problematic because numbers don't stop. There is no finite amount of factors or multiples. There can always be a higher number of both.
You enter at row 73
highest row right side number put to the right of greatest number on the same row on the left= first #. Then get the bottom row right side number on the right of the lowest number on the left side of the same row. That is second # first number - second number= Range
Kr fourth period means the fourth horizontal row on the periodic table....so the element on that row with the highest atomic number is Kr
To find the LCM: write in 2 rows multiples of 6 (top row) and multiples of 9 (bottom row) and find the same number in both rows. 18 is in both rows, so 18 is the LCM of 6 and 9.6.12.18.249.18.27.36
The principal quantum number for the highest energy electron in carbon would be 2. It is easy to spot this, since carbon exists in row 2 of the period table. The row in which an element resides always shows the highest value of n, or the principal quantum number, that an electron can reside in.
Hydrogen's atomic number, 1, shows that hydrogen should appear in the highest row of the periodic table in the leftmost box of that row.
If you can arrange the counters in the shape of a rectangle with at least two in each row and each column then the number is composite. The numbers of row and the numbers of columns are factors of the given number. If the only rectangle you can make is the "degenerate" one, with only one row or only one column, then the number is prime.

It is often referred to as the row header or row heading or row number.
The quantum number of the highest occupied electron orbital in a Bohr model atom corresponds to the atom's period (row) number in the periodic table.
The actinide series is part of the seventh row of the periodic table, which is probably the highest row that contains elements stable enough to be identified.
The row number describes the period. It signifies the number of shells.
