The diagram below shows a partial periodic table. The electron configuration of oxygen is 1s2 2s2 2p4. On the periodic table, fluorine is one space to the right of oxygen. Which of the following electron configurations represents fluorine?

1s2 2s2 2p3

1s2 2s2 2p6 1s2 3s2 3p3

1s2 2s2 2p5

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.

it would only be the stuff in module eight so you need to study all the lessons in that you also could check the flvs

hope this : )
