The general electron configuration for atoms of the halogen group is
1 answer:
Answer:
Explanation:
Halogen group:This group contains Cl,F,Br and I
There are 7 electrons in the outermost shell of each element of halogen family.
Each element of this family required one electron to fill their complete outermost shell.
We know that
Cl=17=
Therefore, the general configuration for atoms of the halogen group is given by

Answer:
A. α = - 1.047 rad/s²
B. θ = 14.1 rad
C. θ = 2.24 rev
Explanation:
A.
We can use the first equation of motion to find the acceleration:
where,
ωf = final angular speed = 0 rad/s
ωi = initial angular speed = (30 rpm)(2π rad/1 rev)(1 min/60 s) = 3.14 rad/s
t = time = 3 s
α = angular acceleration = ?
Therefore,
<u>α = - 1.047 rad/s²</u>
B.
We can use the second equation of motion to find the angular distance:
<u>θ = 14.1 rad</u>
C.
θ = (14.1 rad)(1 rev/2π rad)
<u>θ = 2.24 rev</u>
