1.2.2 Rutherford's Nuclear Model of Atom
Rutherford and his students (Hans Geiger and
Ernest Marsden) bombarded very thin gold
foil with a-particles. Rutherford's famous
d-particle scattering experiment is
represented in Fig. 1.5. A stream of high energy
a-particles from a radioactive source was
directed at a thin foil (thickness - 100 nm) of
gold metal. The thin gold foil had a circular
fluorescent zinc sulphide screen around it.

Fig.1.5 Schematic view of Rutherford's scattering
experiment. When a beam of alpha (a)
particles is "shot" at a thin gold foil, most
of a particles pass through without much
effect. Some, however, are deflected.

Answer 1

1.for making the text look coloured refer the below syntax and ignore the dots

[.tex]\red{the\:text\:appears\:in\:red}[./tex]

result

\red{the\:text\:appears\:in\:red}thetextappearsinred

2.for making the text marquee

[.tex]<marquee>{the\:text\:appears\:like\:this}</marquee>[./tex]

result

= < marquee > {the\:text\:appears\:like\:this} < /marquee > <marquee>thetextappearslikethis</marquee>

3. for making the text look bold

[.tex]\bold{the\:text\: appears\: like\: this }[./tex]

result =

\bold{the\:text\: appears\: like\: this }thetextappearslikethis

4. for showing the exponential value

[.tex]{no.}^{power}[./tex]

result

= {no.}^{power}[ /tex] 5. for showing the square root value [.tex]\sqrt{no.}[./tex] result = $\sqrt{no.}no. </p><p>power</p><p>$5.forshowingthesquarerootvalue[.tex]

no.

[./tex]result=[tex]

no.
