112 (number and identifier)
112 is an integer with distinct mathematical properties, the atomic number of copernicium, and a widely used emergency telephone number. This article summarizes numeric traits, chemistry, emergency use, and other common meanings.
Overview
112 is an integer that appears in mathematics, science, communications and culture. It is used as a simple ordinal or calendar year label (for example, AD 112), as an atomic number, and as a public-safety telephone code in many countries. The symbol "112" therefore serves both as a pure number and as an identifier in several domains.
Mathematical properties
As a number, 112 is even and composite. Its prime factorization is 2^4 × 7, which gives it ten positive divisors: 1, 2, 4, 7, 8, 14, 16, 28, 56 and 112. The sum of all divisors equals 248, and the sum of proper divisors (136) is greater than 112, making it an abundant number. In base representations, 112 is written as 1110000 in binary, 160 in octal and 0x70 in hexadecimal; in ASCII, the decimal value 112 corresponds to the lowercase letter 'p'. It is also a Harshad number in base 10 (112 is divisible by the sum of its digits, 4).
Chemistry and element 112
Atomic number 112 designates the synthetic element copernicium, with the symbol Cn. Copernicium is a transactinide element produced in particle accelerators and has no stable isotopes; its known isotopes have very short half-lives. It is named for the astronomer Nicolaus Copernicus and is of interest primarily to researchers studying the properties of heavy nuclei and relativistic effects on electronic structure.
Emergency telephone number
"112" is widely recognized as an emergency telephone number in the European Union and in many other countries around the world. Dialing 112 connects callers to emergency services such as police, fire and medical responders; on mobile networks it is commonly available free of charge and can often be reached even without an active SIM card. In some locations 112 operates alongside other national emergency numbers and may be redirected to equivalent local services.
Other uses and cultural notes
- As a year marker, "112" can refer to historical years in both AD and BC designations and is used in chronologies and inscriptions.
- In computing and communications, 112 may appear as a code, port, model number or shorthand identifier in technical contexts.
- In popular culture and commerce, simple numeric strings like 112 are often adopted as names for bands, products or routes; one notable example is the American R&B group known simply as "112."
Because the sequence "112" spans numeric, scientific and social domains, disambiguation is commonly required: context determines whether it denotes a mathematical integer, a chemical element, an emergency phone number, a year, or another identifier.
