Protons and neutrons make up the center (nucleus) of the atom, and electrons form shells around the nucleus.

P.), when placed after a number (as in 2500 BP), means "years Before the Present." Archaeologists and geologists generally use this abbreviation to refer to dates that were obtained through the radiocarbon dating technology.
While BP is also used generally as an imprecise estimate of an age of an object or event, the use of it in science was made necessary by the quirks of the radiocarbon methodology.
Tree rings, which keep a record of the amount of carbon in the atmosphere when they are created, are used to calibrate or fine-tune radiocarbon dates to their calendar dates.
Scholars use the science of dendrochronology, which matches those annular rings to known carbon fluctuations.
Long after the Gregorian calendar was established throughout most of the world, atomic clocks have allowed us to adjust our modern calendars with leap seconds to correct for the slowing spin of our planet and other corrections.
But, perhaps the most interesting outcome of all this investigation is the wide variety of modern mathematicians and programmers who have taken a crack at perfecting the matches between ancient calendars using modern technology.
Recall that atoms are the basic building blocks of matter.
Atoms are made up of much smaller particles called protons, neutrons, and electrons.
This has caused many in the church to reevaluate the biblical creation account, specifically the meaning of the word “day” in Genesis 1.
