WILL MARK BRAINLIST IF ANSWER CORRECTLY <3 1) List the groups in order from most reactive to least reactive on the periodic table.

2) Add to the answer in the previous question by stating how many valence electrons are in each group on the periodic table.

Please Explain your answer (not too much detail tho)

Mass is the amount of matter in an object.  weight is the measurement of the pull of gravity on an object.  say for example, you travel to the moon which has a different gravitational field compared to the gravitational field of earth. (gravitational fields: earth = 1, moon = 0.165)  now when you are on the moon, the pull of gravity on you is different than on the earth. and as weight is the measurement of the pull of gravity on an object, that means yes, your weight can and will change on the moon.  however, on the moon, on earth or even on jupiter, the amount of mass inside of you remains the same. meaning your physical mass remains constant.  in conclusion it is possible for your weight to change as your mass remains constant. 

Sorry i dont understand the question can you rephase it?

Iimpact me by the one the yet but him.

Ok so co(g) is not pronoused that. the only clue is that youpronouse it the oppisote way.
