Moving down in a group, the electronegativity decreases due to an increase in the distance between the nucleus and the valence electron shell, thereby decreasing the attraction, making the atom have less of an attraction for electrons or protons.
Answer:
There are 12 nanoseconds in 
.
Explanation:
We need to convert to nanoseconds.
We know that,
Now using unitary method to solve it such that,
So, there are 12 nanoseconds in .
because it can influence how frequently and sufficiently the particles collide depending on the space it has to do so, for example a large surface area would be have a slower rate of reaction and a lower temperature. (the rate of reaction in terms of concentration, it is diffused from high to low)
Chemical energy is converted to thermal energy.
