Answer:

The total number of charge pair without double counting is 6.

Step-by-step explanation:

Given that,

Number of proton = 2

Number of electron = 2

We need to calculate the total number of charges in Hydrogen atom

Using formula for number of charges


n= p+n


n =2+2


n=4

Number of charge in pair is


r = 2

We need to calculate the total number of possible combination of pairs without double counting

Using formula of combination


N=_(n)C^(r)

Where, n = number of charges

r = number of charges per pair

Put the value into the formula


N=_(4)C^(2)


N=(4*3* 2)/(2(4-2))


N=(4*3* 2)/(2*2)


N=6

Hence, The total number of charge pair without double counting is 6.
