Introduction

The periodic table of the chemical elements is tabular method of displaying the chemical elements. The current standard table contains 117 confirmed elements as of October 16 , 2006 (While element 118 has been synthesized, element 117 has not).

Background

I wrote a small program in Visual C++ 6 that display group and period of elements in periodic table. periodic table method returns string(as CString type) that display group and period of element. In PeriodicTable method ANumber parameter means Atomic number of element. This method define in Periodic Table.h inside _PERIDICTABLE structure.

Using the code

A brief description of how to use the article or code.

The methods is:

//
// CString PeriodicTable(int ANumber)
//{
    int T1=0,T2=0;
    int Xe[9]={2,10,18,18,36,54,86,118};
    int FS[14]={1,3,11,19,37,55,87,4,12,20,38,56,88};
    int Period=0;
    BOOL bT=TRUE;
    CString Group="";
    if(ANumber>=5&&ANumber<=9)
    {
        T1=8-(10-ANumber);
