What is the energy of the electron in a helium ion with a charge of +1 in an orbit with a value of n=4?

The energy of the electron in a helium ion is

Explanation:

Given that,

Charge = +1

Value of n = 4

Suppose

We need to calculate the energy of the electron in a helium ion

Using formula of energy

Put the value into the formula

Hence, The energy of the electron in a helium ion is

i think it because equal matrices have equal dimensions, only square matrices can be symmetric. for all indices and . every square diagonal matrix is symmetric, since all off-diagonal elements are zero. in linear algebra, a real symmetric matrix represents a self-adjoint operator over a real inner product space.
