Using your periodic table if you look at it 3-11 are tansition metals so the horizontal Group Number will help if the group number has to digits just remove the one so if it were to be 13, the valence would be 3, if it were 14 the valence would be ,4 if it were 15, the valence would be 5, if it were 16 the valence would be 6, if it were 17 the valence would be 7 if it were group 18 the valence would be 8 so if anymore help needed to explain hit me up
If one of the answers are the coin will float that one would be correct.
Answer:
Change in potential energy is 700.7 J.
Explanation:
Given:
Mass of the object is,
kg
Height to which the object is raised above his head,
m
Acceleration due to gravity is,
m/s²
We know that for a mass
raised to a height
, the change in potential energy is given as:
, where, 
Now, plug in the given values and solve.

Therefore, the change in the potential energy is 700.7 J.
