Explanation:

Group           Most Likely Ionic Charge               Number of Valence Electrons

   I                                 +1                                                           1

   II                                 +2                                                         2

   III                                +3                                                          3

   IV                           +4 or -4                                                     4

   V                                  -3                                                         5

   VI                                 -2                                                         6

  VII                                 -1                                                          7

  VIII                                 0                                                          8

For elements in group IV and above, their ionic charge is (8-number of their valence electrons.)

(Numerical problems) A car is running with the velocity of 72km/h. What will be it's velocity after 5s if it's acceleration is -
kodGreya [7K]

The car's velocity after 5s : 10 m/s

<h3>Further explanation</h3>

Given

velocity=v=72 km/h=20 m/s

time=t = 5 s

acceleration=a = -2 m/s²

Required

velocity after 5s

Solution

Straight motion changes with constant acceleration

\tt v_f=v_i+at

vf=final velocity

vi = initial velocity

Input the value :

\tt v_f=20+(-2).5\\\\v_f=20-10\\\\v_f=10~m/s

The car is decelerating (acceleration is negative) so that its speed decreases

What does the simplified model of the hall effect give for the density of free electrons in the unknown metal?
evablogger [386]
The simplified model of the hall effect proved that the current (electric) in metals are carried by electrons and not protons. The hall effect introduced the hall coefficient which is the ratio of the induced electric field to the current density x applied magnetic field. This coefficient is unique for each type of metal.
