Answer:
Seven

Because all halogens have seven valence electrons, they are “eager” to gain one more electron. Doing so gives them a full outer energy level, which is the most stable arrangement of electrons. Halogens often combine with alkali metals in group 1 of the periodic table.
Answer:
Speed of the runner during video interval is 6.49 m/s
Explanation:
According to the problem,
Number of frames recorded by camera in 1 second = 50
Time takes by camera to record 1 frame = (1/50) s
Time taken by camera to record 77 frames, t = s
Distance covered by the runner during the video recording, d = 10 m
Speed, v =
Substitute the values of d and t in the above equation.
v =
v = 6.49 m/s
Can you please tell what "it" is?
