The atomic mass of fluorine is 18.998 amu and its mass spectrum shows a large peak at this mass. the atomic mass of chlorine is 35.45 amu, yet the mass spectrum of chlorine does not show peak at this mass. explain the difference.

Select all that apply. a beta particle: is electromagnetic energy is an electron has zero charge is emitted from the nucleus has a +2 charge has a -1 charge

Based on its chemical properties, identify the position of each chemical family on the periodic table.

Movement that is like a t a type of wave that transfers energy where the particles in the medium move in a circle motion while the energy travels left or right. a type of wave that transfers energy where the particles in the medium move perpendicular to the direction in which the energy is traveling. transfers energy from one location to another a type of wave that transfers energy where the particles in the medium move parallel to the direction in which the energy is traveling. movement that is back and forth, like an equal sign = 1. wave 2. parallel movement 3. perpendicular movement 4. transverse wave 5. longitudinal wave 6. surface wave
