This figure was published in a 2017 study by the Annals of Internal Medicine which compared data from 1994, indicating 40% of recent gun acquisitions were completed without a background check, to a 2015 survey which found that 22% of recent gun transfers (purchased and nonpurchased) were completed without a background check. The current federal law allows people not ``engaged in the business'' of selling firearms to sell firearms without a license or records. The Coalition to Stop Gun Violence (CSGV) states that the National Instant Criminal Background Check System has prevented over two million felons and other prohibited persons from purchasing firearms. According to the CSGV, the law also has a prohibitive effect, that deters illegal purchases.

It determines the atomic mass of atoms. Because protons and neutrons both are baryons, the mass number A is identical with the baryon number B as of the nucleus as of the whole atom or ion. The mass number is different for each different isotope of a chemical element. This is not the same as the atomic number (Z) which denotes the number of protons in a nucleus, and thus uniquely identifies an element. Hence, the difference between the mass number and the atomic number gives the number of neutrons (N) in a given nucleus: N = A − Z (\displaystyle N=A-Z) .
