Question

the species which has the maximum charge to mass ratio is​

Answer 1

Answer:

Answer: Option (b) is the correct answer.

Explanation:

A deuterium means [/tex]. It contains 2 times the mass of an electron and since it has only one electron or proton. So, charge will be 1 times charge of an electron.

Therefore, its mass will be  = . And, charge will be .

Charge to mass ratio of deuterium is .

Similarly, hydrogen atom means . So, there is just one electron and mass is also 1 times the mass of an electron. Hence, its charge to mass ratio is .

Therefore, for hydrogen charge to mass ratio is  or .

Helium is .  means there is only one electron. So, mass will be  = . And, charge will be .

Charge to mass ratio of helium is  or .

Whereas  means there are two electrons. So, mass will be  = . And, charge will be .

Charge to mass ratio of helium is 0.

Thus, we can conclude that hydrogen has maximum charge to mass ratio.
