No, the breaking of sigma bonds does not belong to mesomerism. Mesomerism, also known as resonance, involves the delocalization of electrons within a molecule through the shifting of pi bonds and lone pairs. It does not involve the breaking of sigma bonds, which are the strong covalent bonds formed by the overlap of atomic orbitals. Breaking sigma bonds would involve the actual cleavage of the covalent bond, which is a different process than mesomerism. **

The value of bonds in your portfolio may have decreased due to changes in interest rates. When interest rates rise, the value of existing bonds decreases because they are paying lower interest rates than newly issued bonds. This is known as interest rate risk. Even though EU government bonds are considered safe investments, they are still subject to fluctuations in interest rates, which can impact their value. Additionally, other factors such as economic conditions, inflation expectations, and market sentiment can also affect the value of bonds in your portfolio. **

Investing in bonds involves purchasing debt securities issued by governments or corporations, which pay a fixed interest rate over a specified period of time. In contrast, investing in a bank account typically involves depositing money into a savings or checking account, where it earns a variable interest rate set by the bank. Bonds generally offer higher potential returns than bank accounts, but they also carry a higher level of risk. Additionally, bonds have a maturity date, while bank accounts provide more immediate access to funds. **

Additionally, global events, economic uncertainty, or changes in government policies can also impact the value of these securities. It's important to monitor the market and economic conditions to understand the reasons behind the decrease in value of your bond holdings. **
