An electron configuration that is farther away from 8 or 1, an electron valence that is either closer to 8 or 1 will become less stable. This is because they will either by trying hard to loose an electron to have a full 8 or gain one to become. Full 8 valence
Answer:
Mountainous roads are winding and gently sloping in order to reduce the effect of steepness which causes more downward gravitational pull to the vehicles on it. A steeper sloped road would slow the car down to a greater extent that an gently sloping one.
I think there both energy
V1M1c1 = V2M2c2
29 x 0.26 x 1 = V2 x 0.4 x 2
V2 = 9.425
