No! This is a completely static website with no backend or database. All features work immediately without any registration or login required. Your progress and preferences (like dark mode) are stored locally in your browser.

The interactive periodic table allows you to:

• Search: Type element name, symbol, or atomic number in the search box
• Filter: Click category buttons to show only specific element groups (alkali metals, noble gases, etc.)
• Hover: Move your mouse over any element to see detailed information in a tooltip
• Click: Elements are clickable for more detailed views (if implemented)

The equation balancer uses JavaScript algorithms to balance chemical equations. Simply:

1. Enter reactants separated by + (e.g., "H2 + O2")
2. Enter products separated by + (e.g., "H2O")
3. Click "Balance Equation"
4. The balanced equation will appear with correct coefficients

Note: This is a simplified balancer. Complex equations may require manual verification or more advanced tools.
