Question

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?

Answer 1

Answer:

The energy of the electron in a helium ion is $-5.44\times10^{-19}\ J$

Explanation:

Given that,

Charge = +1

Value of n = 4

Suppose $k=2.179\times10^{-18}\ J$

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

Using formula of energy

$E_{n}=-k\dfrac{z^2}{n^2}$

Put the value into the formula

$E_{n}=-2.179\times10^{-18}\times\dfrac{2^2}{4^2}$

$E_{n}=-5.44\times10^{-19}\ J$

Hence, The energy of the electron in a helium ion is $-5.44\times10^{-19}\ J$
