Question

all elements with an atomic number above 82 will have unstable nuclei. this means everything above lead on the periodic table can go through nuclear decay. radiation is emitted in the form of particles or high - energy waves and more stable nuclei will be produced. options: heat or light, particles or high - energy waves, hydrogen atoms

Explanation:

All elements with an atomic number above 82 have unstable nuclei. During nuclear decay, radiation is emitted in the form of particles or high - energy waves. Lead has an atomic number of 82, and elements above it undergo decay to form more stable nuclei.

Answer:

Particles or high - energy waves; Lead; more stable nuclei
