During a physical change, the mass is conserved because it isn't permanently changed, like a chemical change. A chemical change would be something like burning a piece of paper, and a physical change would be something like cutting up pieces of paper (can be put back together).

Which phrase best describes a period on the periodic table?

dybincka [34]

The phrase which best describes a period on the periodic table is: a row of elements
