Many of the largest elements were made in a collider $($ramming particles into each other at enormous speeds$).$ Based on the graph from the previous question, is the periodic table endless? Will we always be able to synthesize larger and larger elements?$^2$

Label each of the following as alpha decay, beta decay, gamma radiation, positron emission or electron capture.

a$.{?}_{53}^{125}I+{?}_{-1}^{0}e{?}_{52}^{125}Te$

b$.{?}_{43}^{99}Tc{?}_{44}^{99}Ru+{?}_{-1}^{0}e$

c$.,{?}_{94}^{240}Pu{?}_{94}^{240}Pu+{?}_0^0$

d$.{?}_{95}^{241}Am{?}_{93}^{237}Np+{?}_2^{4}He$

e$.{?}_{19}^{38}K{?}_{18}^{38}Ar+{?}_1^{0}e$

${?}^2$ Fun fact: The International Union of Pure and Applied Chemistry $($IUPAC $-$ a bunch of very important scientists, I$\text{'}$m sure$)$ requires an element to have a lifetime longer than ${10}^{-14}$ seconds $($or $10$ femtoseconds$).$
