How do you think the scientists were able to organize and sort the periodic table of elements? (What do we know about elements, and how did that help them?)

Most non-metals were gases and liquids, brittle, and poor conductors of heat and electricity. Scientists then came up with the idea that they could arrange the element by the atomic mass number. Every element has its own unique atomic mass number because elements have different numbers of protons and neutrons.

the offspring would all be white. if the parents are both white flowers then they have the genotype rr, which when crossed results in an all white punnet square.

i think it’s c but i might be wrong. if i am let me know! have a good rest of your day as well!
