Which of the following nuclides will likely undergo a beta emission for its dominant radioactive decay mode? a) yttrium-76
b) tin-105
c) cesium-120
d) barium-146

barium-146

Explanation:

Beta emission is said to occur when a neutron is converted to a proton, an electron and a neutrino. Beta emission leads to a decrease in the Neutron/Proton ratio.

Beta emission is common for heavier nuclei having a large number of neutrons. Barium-146 has 90 neutrons, hence it is more likely to undergo beta emission than other nuclides stated among the options.

the molecules move in straight line until they collide with each other or with the walls of the container. collisions are perfectly elastic; when two molecules collide, they change their directions and kinetic energies, but the total kinetic energy is conserved.

explanation:

plasma - state of matter made up of electrically charged particles
