Answer is: <span>negative beta decay. </span> Nuclear reaction: ¹⁴C → ¹⁴N + e⁻ + νe (electron antineutrino). <span>In beta minus decay (atomic number Z is increased
by one, from 6 in carbon to 7 in nitrogen) neutron is converted to a proton and
an electron and an electron antineutrino. </span><span>Beta decay is radioactive decay in which a beta
ray and a neutrino are emitted from an atomic nucleus.</span>
The scale is talking about how if on the model it states the wall is 1 foot you would make it 44 feet The windows and doors are just there to make sure you don’t forget them. Hope this helped! :D
