Name the sub-atomic particles.

Draw the atomic structure and explain the position of the sub-atomic particles.

Name the instrument to measure sub- atomic particles.

What are sub atomic particles?

The kinetic energy of sub-atomic particle is 5.85 xx 10^(-25) J. Calculate the frequency of the particle wave. (Planck’s constant, h = 6.626 xx 10^(-34) Js)

Assertion: Very large distances such as distance of a planet or star can be measured by parallax method. Reason: For measuring small masses of atomic/ sub-atomic particles, mass spectrograph is used.
