Un compus al unui metal M care contine 20 protoni in nucleu, contine alaturi de acesta oxigen si un alt nemetal Y ce are configuratia electronica K=2e, L=8e, M=6e. Stiind ca masa acestui compus respecta relatia M=6 * nr neutronilor din nucleul Y, sa se determine prin calcul formula compusului dat.

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
