Is selenium an atomic or molecular element?
Selenium is an atomic element with 34 electrons and 34 protons. Stable versions (isotopes) have from 42 to 44 neutrons. It is necessary in very small amounts to support life, otherwise it is poisonous. Selenium at one time was the main source for transistors and diodes because of its semiconductor properties.
Is selenium fluoride polar?
Selenium fluoride bond is polar because fluorine is more electro-negative than selenium. Hence the shared paired of electrons are more towards fluorine giving fluorine a partial negative charge and selenium a partial positive charge.
