C. Protons, neutrons, electrons
The atomic mass would be 13 amu.
You can calculate this by adding the number of protons and neutrons.
7 protons+6 neutrons
=13 amu.
Atomic number is Z. Z=number of protons, so Z=11
Molecules are cooler so they bocme more dense.. move very slow, have less kinetic energy and are not in random motion.
Statement describe both theory and law .
