Answer: 8
Explanation:
Non metals which have 4 electrons in the outer shell i.e in the valence shell bond with the other similar non metals having 4 electrons in their valence shell. This bond is known as covalent bond in which the two atoms share their valence electrons with each other in order to complete their valence shell. These atoms seeks to have 8 electrons in order to attain noble gas configuration.

Answer:
(a) 80.36 m/s^2
(b) 0.0933 second
Explanation:
initial velocity, u = 7.5 m/s
final velocity, v = 0 m/s
distance moved, s = 0.350 m
(a) Let a be the deceleration.
Use third equation of motion
a = 80.36 m/s^2
Thus, the deceleration is 80.36 m/s^2.
(b) Let the time taken is t
Use first equation of motion
v = u + a t
0 = 7.5 + 80.36 x t
t = 0.0933 second
