Metalloid

Explanation:Elements in the periodic table are classified as either metals, non-metals and metalloids.Metalloids are elements that exhibits both metallic and non-metallic properties. Arsenic is an example of a metalloid.Metals form ions by losing electron(s) while non-metals form ions by gaining electron(s).Metalloids on the other hand reacts by either gaining or losing electron(s) a property which indicates both metalliic and non-metallic property.

What is the question

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.
