10161.6 Lanthanum-140 can also emit beta radiation and change into cerium. Complete the equation showing the decay of lanthanum (La) 140 into cerium (Ce).

Explanation:

Beta emission occurs when a neutron is converted to a proton, an electron and a neutrino. This phenomenon reduces the neutron-proton ratio(N/P).

When a beta emission occurs, the mass number of the daughter nucleus is the same as that of the parent nucleus while the atomic number of the daughter nucleus increases by one unit.

We can see this explanation above in the reaction described in the answer section.

i look it up online and i'll tell you

under a microscope, cancer cells may look very different from normal cells. they often have different sizes and some may be larger than normal while others are smaller. cancer cells are often abnormally shaped and the control centre of the cell (the nucleus) may have an abnormal appearance.

i think? ?
