Which of the following group 15 elements has the greatest metallic character?
(1) nitrogen (3) antimony
(2) phosphorus (4) bismuth

The answer is no. 4. Bismuth (Bi)
Across the period, from left to right, metallic character decreases, meaning, when it is going down, the last element in a group will have the most metallic character. Since Bismuth (bi) is the last element, it is the most metallic. The arrangement of the group 15 elements in ascending rate of metallic character is: N (Nitrogen) P (Phosphorus), As (Arsenic), Sb (Antimony) and Bi (Bismuth). Bismuth has the lowest rate of electronegativity and ionization energy thus, it is more likely to lose an e- than the rest of the elements of the said group, which is why it is considered the most metallic.

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. 

So what you would do is go through and add 3 teaspoons(tsp) 6 times because of the 6 tablespoons(tbsp). which will give you an answer of 18. another way is to multiply 3x6=18.
