Question

What will be an ideal response?

Answer 1

```
class Element {
public:
Element () {}
Element (int); // constructor with atomic number
int getAtomicNumber() const; // accessor
string getName() const; // accessor

private:
int N; // Atomic Number
string Name, // Element Name
Symbol, // IUPAC Chemical Symbol
Class; // column class, ie alkali_metal, halogen, etc
double Z; // Atomic Weight
int e[7]; // electronic configuration

friend istream& operator>> (istream&, Element&);
friend ostream& operator<< (ostream&, const Element&);
};

int main()
{
Element elem1;
