Question

drag and match match the following terms with their correct definitions. half - life weight mass number molecular weight matter answer the sum of all the atomic weights in a compound anything that has mass and occupies space effect of gravity on mass of an object the time required for half of a given amount of the isotope to decay total number of protons and neutrons

Explanation:

Half - life is the time for half of an isotope to decay. Weight is the effect of gravity on an object's mass. Mass number is the total of protons and neutrons. Molecular weight is the sum of atomic weights in a compound. Matter is anything with mass and volume.

Answer:

Half - life: The time required for half of a given amount of the isotope to decay
Weight: Effect of gravity on mass of an object
Mass number: Total number of protons and neutrons
Molecular weight: The sum of all the atomic weights in a compound
Matter: Anything that has mass and occupies space
