5 f
7 a
Looks like a slightly tricky one . Enrico Fermi (Italian) was at Los Alamos, involved in nuclear fission which is how nuclear reactors "work". He got a nobel prize for, like the rest o them, being clever. Henri Beqcuerel (French) was also involved in nuclear physics somewhere. Another nobel for the same sort of reason (clever).

Answer 2

can you help me plz?

Answer 3

hello?

Answer 4

Hello to whom ?

Answer 5

to any one

Answer 6

6 could be Becquerel, prob is that Madame Cuire (nobel) also was involved. The q is trick, as it stands ..

Answer 7

knowing what you need would help you to be helped ... ???????

Answer 8

1. First Nuclear Reactor: a. Fermi (see Chicago Pile 1)
2. 1/0 η: c. neutron (by elimination and following osprey's answer, not sure about this notation)
3. decaying nuclei: e. fission
4. number of neutrons and protons: b. atomic mass (strictly speaking: mass number)
5. builds heavier elements: f. fusion
6. discovered radioactivity: d. Becquerel (but Marie Curie coined the term radioactivity)
7. unit of radiation: a. curie (note the small letter)
