Which of the following best describes a metal? brittle, shiny, and solid brittle, dull, and low density malleable, shiny, and able to conduct heat or electricity malleable, dull, and solid, liquid, or gas at room temperature?

Answer : The correct option is, Malleable, shiny, and able to conduct heat or electricity.

Explanation:

Metals : Metals are the elements which can easily loose electrons and forms cations.

Properties of metals :

They are lustrous (shine).They are malleable and ductile (flexible).They conduct heat and electricity.The metallic oxides are basic in nature.They form cations in an aqueous solution.

Non-metals : Non-metals are the elements which can easily gain electrons and form an anion.

Properties of non-metals :

They are non-lustrous.They are brittle and hard in nature.They do not conduct heat and electricity.The non-metallic oxides are acidic in nature.They form anions in an aqueous solution.

Hence, from the given options the correct option for metal is, Malleable, shiny, and able to conduct heat or electricity.

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.
