Answer:
the material has two different color crystals
Explanation:
In the nucleus there are two main subatomic particles: The protons and the neutrons. The number of protons in the nucleus determines the element the atom is: 1 proton = hydrogen , 99 protons = Einsteinium , 6 protons = carbon etc.
The number of neutrons in the nucleus varies from atom to atom, even atoms of the same element. This causes the mass of the nucleus to vary slightly and can effect properties such as stability or type of nuclear decay. Atoms of the same element with different masses are called isotopes. They differ by the number of neutrons with the proton in te nucleus:
1 proton + 0 neutrons = 1 particle in the nucleus = hydrogen
1 proton + 1 neutron = 2 particles in the nucleus = deuterium
1 proton + 2 neutrons = 3 particles in the nucleus = tritium
Hope this helps

Units of measurement are the terms that we use to describe the size of something. You probably know that units include things like seconds, kilograms, meters, and so forth.
Without standard units of measurement, scientists would have a huge problem understanding what other scientists were saying. After all, if I were to refer to a meter as "the length of my leg" and another scientists were to refer to it as "the length of a Saint Bernard dog", we'd have a lot of trouble when it came to do actual science. To avoid this problem, the SI system of units gives us a convenient and, more importantly, standard set of units that we can agree on.
