Phosphorus does not occur freely in nature as a result of its reactivity with oxygen and other
gasses as well as other oxygenated
substances. However, it is commonly found in
various chemical compounds, a few examples
of which are phosphorus trioxide, phosphorus
pentoxide and phosphorus trichloride.​

c. orbital shape i hope this is correct

the objects have the same charge.

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.
