Answer 1

Answer:

Note the usefulness of the periodic table in predicting likely ion formation and charge (Figure 2). Moving from the far left to the right on the periodic table, main-group elements tend to form cations with a charge equal to the group number.

Answer 2

Step-by-step explanation:

Suppose d is the total distance between two cliffs and x is the distance between the man and one cliff.

2x=v×t1

x=2v×t1

   =2340×1.5

   =255 m

2(d−x)=v×t2

(d−x)=2v×t2

(d−x)=2v×t2

(d−x)=2340×3.5

(d−x)=595 m

d=595+x

    =595+255

    =850 m
