The elements that exist as monatomic molecules at stp are the noble gases. These include He, Ne, Ar, Kr, Xe, and Rn.
Nitrogen (N2) is the Group 15 element that exists as diatomic molecules at standard temperature and pressure (STP).
No, fluorine is a diatomic gas at standard temperature and pressure (STP), meaning it exists as F2 molecules, not as single F atoms.

A gas at STP.
At standard temperature and pressure (STP), the element that is malleable and a good conductor of electricity is copper.
Bromine is a chemical element and a liquid at room temperature, so it can be a solution when dissolved in a solvent like water or organic solvents. It is commonly used as a reagent in chemical reactions and as a disinfectant.
