68
95
99
The 1st three stand deviations.............95 is 27 from 68...........another e.......99 and 95 are connected by 3 nines.......3 * 9 = 27.........yet another e.........
68 and 95 are like the square root of 2.........which starts ....1.414..........b/c adding single digits to double digits,.......6 + 8 = 14.......9 + 5 = 14..........and like 14i.....of 1/2 + 14i.....the 1st zero...........68 is backwards in e..........18281828459045........the dividing line.....is between the tenth and 11th number......like 11/10.......the 5th term of Euler's product.........8 then 6...........two strings of numbers..............68% backwards........reflexive symmetry..............68, 95 and 99.....the 1st 3 stand deviations.......said like that is like 13....whose square root is like full circle..1/2....the critical line...1/2 in exponents is a square root, Dr. Reimann.....
And....the 1st 3 numbers of pi add to 8..........3.14.....a triangle, a circle......and a square.......the square root of 8 is like e.................an imaginary e.........2.828......is how the square root of 8 starts out....................which simplifies to 2 times the square root of 2......which is like 2+ 2 = 4......2 * 2 = 4....balance........................the 1st 3.....truncating pi there is imp...............1 + 1/2 + 1/3.........2 and 3......the 1st 2 primes......and the 1st two fractions/overtones in the harmonic series..........overall the 1st 3 terms.......like 13.......in 14.13i.......the closest prime to the 1st zero...truncating pi.....at the 1st 3 numbers.....give three imp geometric figures......the most common..a circle........only has one side......3.1415..........the 1st repetition in pi......is the 4th number......a 1......like 14 or 41......41 is the 13th prime.....
And.......68, 95 and 99................the amount of data NOT within that particular deviation.....becomes........32 %, 5%, and 1 %................5 and 1......like 15......like 3/2 = 1.5.......1st 5 primes.....1st 5 non primes..........................3/2 = 1.5..........3 and 2........2 and 3.....reflexive symmetry.,,............and like the 1st two primes...........................32 is symmetrical with the next two deviations.......after all....if 68% of the data is within one standard deviation from the norm....then 32 % is not............15/10............using 50 as the dividing line......of the 1st 25 primes....about 50
50........the circumference of a 18 by 7 rectangle......like the periodic table......

Each chemical element has a unique atomic number (Z) representing the number of protons in its nucleus.[n 2] Most elements have differing numbers of neutrons among different atoms, with these variants being referred to as isotopes. For example, carbon has three naturally occurring isotopes: all of its atoms have six protons and most have six neutrons as well, but about one per cent have seven neutrons, and a very small fraction have eight neutrons. Isotopes are never separated in the periodic table; they are always grouped together under a single element. Elements with no stable isotopes have the atomic masses of their most stable isotopes, where such masses are shown, listed in parentheses.[6]
In the standard periodic table, the elements are listed in order of increasing atomic number Z (the number of protons in the nucleus of an atom). A new row (period) is started when a new electron shell has its first electron. Columns (groups) are determined by the electron configuration of the atom; elements with the same number of electrons in a particular subshell fall into the same columns (e.g. oxygen and selenium are in the same column because they both have four electrons in the outermost p-subshell). Elements with similar chemical properties generally fall into the same group in the periodic table, although in the f-block, and to some respect in the d-block, the elements in the same period tend to have similar properties, as well. Thus, it is relatively easy to predict the chemical properties of an element if one knows the properties of the elements around it.[7]
