value to the industry.

to be more fully described later.

in the years to come.

10. Dalton was the first to deduce scientifically an atomic
theory from experimental data.
11. The first trans-uranium element to be made was a
neptunium isotope Np233.
12. This author is the first to note definitely the crystal
lization of vitrous silica.
13. Alpha-radiation was the first radiation to be studied
in detail.
14. There was only one signal to be detected.
15. There are some other properties of water to be
considered at this point.
16. There is a particular question to be discussed at length.

17. Neutrons serve as particles with which to bombard
nuclei.
18. There is not very much experimental data on which
to base a decision between these two possibilities.
19. When a crystal expands each molecule gets somewhat
larger space in which to carry out thermal oscillation.

20. The amount of polonium to be obtained from a
uranium mineral can be simply calculated.
21. There are some other groups of compounds to be
mentioned.
22. Joule was the first to note definitely this phenomenon.
23. The procedure to be followed in making the acid
extractions depends on whether or not starch is present in
the mixture.
24. There are only a finite number of wave numbers to
characterize electronic states.
25. Polonium was the first of the radioactive elements to
be isolated by the chemists.
26. Many methods are available for the preparation of
oxygen, the particular method to be employed must be
determined by cost and convenience.
27. The most accurate method for determining hydrogen
ion concentration makes use of the hydrogen electrode, about
to be described.
28. This theory will be adequate for practical applications
through centuries to come.
