What happens when atoms bonds?​

Chemistry
1 answer:
jok3333 [9.3K]4 years ago

Atoms form chemical bonds to make their outer electron shells more stable. ... An ionic bond, where one atom essentially donates an electron to another, forms when one atom becomes stable by losing its outer electrons and the other atoms become stable (usually by filling its valence shell) by gaining the electrons.

Explain the difference between an endothermic and an exothermic reaction using the concepts of potential energy, stability, and
kakasveta [241]
An Exothermic reaction releases energy into the surroundings and so the products have more potential energy then the reactants. The enthalpy change is a negative value. Whereas, an endothermic reaction involves the absorption of energy into the system and so the reactants have more potential energy than the products. The enthalpy change is a positive value. This is clearly represented in energy profile diagrams.

GrogVix [38]

The frequency and energy of most energetic of these photons is1.36*10^{15} Hz and 9.04*10^{-19} J respectively.

The high energy photons will have least wavelength. Taking the given less wavelength for calculation of frequency and energy of photons.

λ = 2200  Å

Also, we know, 1 Å = 10^{-10} m

So, λ = 2200*10^{-10}

λ = 2.2*10^{-7}<em> </em>m

Now, calculating frequency using the formula -

c = fλ, where c is speed of light, f is frequency and λ is wavelength.

We know, c = 3*10^{8} m/s

f = c/λ

f = \frac{3*10^{8} }{2.2*10^{-7} }

frequency = 1.36*10^{15} Hz

Now, calculating Energy through the formula -

E = hf, where E is energy, h is planck's constant and f is frequency

Value of planck's constant = 6.63*10^{-34} Js

E = 6.63*10^{-34}*1.36*10^{15}

Energy = 9.04*10^{-19} J

Thus, frequency and energy of photons is 1.36*10^{15} Hz and 9.04*10^{-19} J respectively.
