According to Bohr's model, the energy of n = 4 electron in a hydrogen atom is 1.3625 × 10⁻¹⁹J

<h3>Bohr's Model of Hydrogen Atom</h3>

According to the postulates given by Bohr, electrons revolve around the nucleus in fixed circular orbits which are called stationary orbits or stationary states.

The energy of electrons in a stationary state is fixed and given by,

E_n = \frac{-2\pi^2me^4}{n^2h^2} Z^2

where, m = mass of electrons = 9.1 x 10⁻³¹ kg

e = charge on electron = 1.602 × 10⁻¹⁹ C

n = no of orbits

h = Planck's constant

Z= atomic number of H-like particles

After calculating all the constants values, we get

E_n= \frac{-2.18 \times 10^-^{18}}{n^2} \times Z^2\\\\E_n= \frac{-2.18 \times 10^-^{18}}{4} \times 1^2

= 0.13625 × 10⁻¹⁸

= 0.13625 × 10⁻¹⁹ J

Hence, the energy of n = 4 electron in a hydrogen atom is 1.3625 × 10⁻¹⁹J

beks73 [17]

Answer:  a)  _{74}^{186}\textrm{W}

b) _{80}^{201}\textrm{Hg}

c)  _{34}^{76}\textrm{Se}

d) _{94}^{239}\textrm{Pu}

Explanation:

General representation of an element is given as:_Z^A\textrm{X}

where,

Z represents Atomic number

A represents Mass number

X represents the symbol of an element

Mass number is defined as the sum of number of protons and neutrons that are present in an atom.

Mass number = Number of protons + Number of neutrons

In an atom, when neutrons or protons are lost or gains, it directly affects the mass number of an atom.

Atomic number is defined as the number of protons or number of electrons that are present in an atom.

It is characteristic of a particular element.

Atomic number = Number of electrons = Number of proton

a) Z 74, A 186: _{74}^{186}\textrm{W}

b) Z 80, A 201: _{80}^{201}\textrm{Hg}

c) Z 34, A 76: _{34}^{76}\textrm{Se}

d) Z 94, A 239.: _{94}^{239}\textrm{Pu}
