Atomic number = protons
Protons = P Electrons = E P = E
Atomic mass = Neutrons + Protons
Atomic number = atomic mass = neutrons
P = E
AM - AN = N
Example:
Calcium = 20 Protons 20P = 20E
Atomic mass - atomic number = neutrons :)
This doesn't seem like a question -_-
A beta particle.<span>β
</span> Looking at the particles before and after for the decay, you'll see that there is a total of 214 neutrons and protons both before and after the radioactive decay. But you'll also see that before the decay, there were 82 protons and after the decay, there are 83 protons. So a neutron was converted to a proton which means that a negative charge had to be emitted, so it's a beta decay where a neutron emits a beta particle (an electron). The beta particle can be represented as a greek beta <span>β</span> followed by a minus sign, giving β-, or as a "e" followed by a minus sign, so e-
Answer:
B or C
Explanation:
Alchemy rely a lot on the spiritual connections to the four elements and they are fire, water, earth and air while chemistry is a lot more logical, factual and scientific based. Also, chemistry is considered as science, while alchemy is not.
Alchemy was based more on experimentation and had little basis in science. Chemistry utilizes both experimentation and scientific practices. Modern chemistry basically relies on scientific theories and experimental results, but the alchemy was a blend of myths, religion, magic, astrology, philosophy, and spirituality.
