What structural formula represents 4 electrons shared between two atoms?
1 answer:
Sharing of 4 electrons between two atoms results in two double bonds. This can be see in the case of oxygen molecule (O2)
Atomic number of O = 8
Electron configuration of O = 1s²2s²2p⁴
Valence electron configuration: 2s²2p⁴
When 2 O atoms combine they share 4 electrons to form 2 double bonds. In addition, there are two lone pairs on each O atom.
Structural formula: O=O

Explanation:
it is almost zero .this is because the distance and the electrostatic force are inversely proportional
Thermal energy Thermal energy <span>Thermal energy</span>
We can use the formula of the moment of inertia given by:
Where:
r = Distance from the point about which the torque is being measured to the point where the force is applied
F = Force
I = Moment of inertia
α = Angular acceleration
So:
Answer:
12 rad/s²
