FALSE. Mass is a measure of the amount of matter within an object. Weight is the force of gravity on a mass. To get weight from mass, multiply mass by the gravitational constant of whatever planet you are on. MASS IS NOT WEIGHT!!!
By the law of conservation of energy, matter cannot be created or destroyed. It can only be converted from one form to another. Thus, the weight of matter cannot change.

Mass is the amount of matter in an object. You cannot have mass-less matter. If you have matter, than it contains some amount of mass.
False. All matter, including living matter, contains traces of radioactive isotopes.

Technically false, because of the words "spin around". That's not how elecgtrons really work. They exist as spherical standing probability functions. If that's what you meant by "spin around", then yes, it's true.
It takes up space and has mass.
False - an electron is about 1/1836 the mass of a proton.
