A typical grain of sand is primarily composed of silicon dioxide (SiO₂). Given that a single silicon atom has 14 electrons and each oxygen atom has 8, a molecule of SiO₂ contains 22 electrons. If we consider a grain of sand to contain approximately 1 billion (10^9) SiO₂ molecules, it would have around 22 billion (2.2 x 10^10) electrons. However, the exact number can vary based on the grain's size and composition.
