The diagram above shows a mix of two substances: a gray solid that smells like flowers and a gray solid that smells like bleach. One of the ending substances was a white solid. Explain how the ending
repeating substances were created using the starting substances. (examples of how atoms that
make up starting substance(s) rearrange to form different group of atoms)

1. a)c-14 has two more protons

2. d)they have different numbers of protons, neutrons, and valence electrons; they are all gases at room temperature.

3. c) iron and nickel.

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
