Solution:
Given:
Velocity of an electron in the second orbit of H atom = v
Velocity of electron in the first orbit of Li^2 = ?
We know that the velocity of an electron in different orbits of an atom is given by:
v = (2.18 x 10^-18)/n where n is the principal quantum number
Velocity of an electron in the second orbit of H atom (n=2) is given by:
v = (2.18 x 10^-18)/2 = 1.09 x 10^6 m/s
To find the velocity of electron in the first orbit of Li^2, we need to calculate the value of n for Li^2.
Li^2 has two electrons, therefore, the electronic configuration of Li^2 is 1s^2 2s^1.
The first electron is present in the first orbit (n=1) and the second electron is present in the second orbit (n=2).
Therefore, the velocity of electron in the first orbit of Li^2 (n=1) is given by:
v = (2.18 x 10^-18)/1 = 2.18 x 10^6 m/s
Thus, the correct option is (3) v.
Answer: 3) v
