ATOMIC DETAILS. “The atomic number is the number of protons in an atom of an element. By definition, atoms have no overall electrical charge. That means that there must be a balance between the positively charged protons and the negatively charged electrons. Atoms must have equal numbers of protons and electrons. Number of Protons = Atomic Number. Number of Electrons = Number of Protons = Atomic Number. Number of Neutrons = Mass Number - Atomic Number.” https://lnkd.in/eunrvYj View in LinkedIn

STARTING POINT. “A fully ionized hydrogen atom is a proton. There is ionized hydrogen, proton — same thing.” http://www.astronomycast.com/transcripts/AstroCast-080922_transcript.pdf View in LinkedIn

STEPPING STONES. “Okay so one proton is hydrogen. Two protons is helium. Three protons is lithium, etc. So, that’s where you go up with the numbers. Whenever you see gold or lead, the first number is the number of protons and if you add another proton, you have a new element, right?” http://www.astronomycast.com/transcripts/AstroCast-080922_transcript.pdf View in LinkedIn

ABC OF ALL MATTER. “It all comes down to proton and neutron number at the end of the day. The number of protons tells you what type of element it is. So, you have hydrogen with one proton; helium with two protons and you build your way up through the periodic table adding more and more protons.” https://lnkd.in/efDcCRq View in LinkedIn

NEXT PART. “But the thing is there’s also this thing called a Neutron. Some atoms in order to be stable have to have both protons and neutrons.” http://www.astronomycast.com/transcripts/AstroCast-080922_transcript.pdf View in LinkedIn

“NEUTRONS in the core. You end up with things like helium-4 which is a helium atom which is number 2 on the periodic table. That 4 means that it has four bits, two protons and two neutrons sitting in its nucleus. Helium-4 is like one of the most stable things that you get.” http://www.astronomycast.com/transcripts/AstroCast-080922_transcript.pdf View in LinkedIn

BUILDING ELEMENTS. “Then we build our way up through the periodic table creating heavier and heavier things through different types of processes. In some cases we just add a proton and it grows. In other cases we add a bunch of neutrons and these neutrons decide to flip what they are between protons decaying through a process called the reverse beta decay.” http://www.astronomycast.com/transcripts/AstroCast-080922_transcript.pdf View in LinkedIn
