Atom
A proton is positively charged. The number of protons in the nucleus ofan atom is the atomic number for the chemical element. A proton has a rest mass, denoted m p, of approximately 1.673 x 10 -27 kilogram (kg). A neutron is electrically neutral and has a rest mass, denoted m n, of approximately 1.675 x 10 -27 kg. The mass of a proton or neutron increases when the particle attains extreme speed, for example in a cyclotron or linear accelerator.
An early model of the atom was developed by the physicist ErnestRutherford in 1912. He was the first to suggest that atoms are like miniature solar systems, except that the attractive force is not caused by gravity, but by opposing electrical charges. In the so-called Rutherford atom, electrons orbit the nucleus in circular paths. Niels Bohr revised Rutherford's theory in 1913. In the Bohr atom,the negatively charged electrons orbit the nucleus at specific mediandistances.
These distances are represented by spheres, called shells, surrounding the nucleus. Electrons can move from shell to shell. When an electron absorbs enough energy, it moves to a larger, or higher, shell.
About This Game ATOM RPG is a post-apocalyptic indie game, inspired by classic CRPGs: Fallout, Wasteland, System Shock, Deus Ex, Baldur's Gate and many others. In 1986 both the Soviet Union and the Western Bloc were destroyed in mutual nuclear bombings. You are one of the survivors of the nuclear Holocaust. An atom is the basic unit of an element. An atom is a form of matter which may not be further broken down using any chemical means. A typical atom consists of protons, neutrons, and electrons.
When it loses a certain amount of energy, it falls to a smaller, or lower, shell. The total mass of an atom, including the protons, neutrons andelectrons, is the atomic mass or atomic weight. Electrons contribute only a tiny part of this mass. For most practical purposes, the atomic weight can be thought of as the number of protons plus the number of neutrons.
Carbon Atom
Because the number ofneutrons in an atom can vary, there can be several different atomic weights for mostelements. Atoms having the same number of protons, but different numbers ofneutrons, represent the same element, but are known as different isotopes of that element. Theisotope for an element is specified by the sum of the number of protons andneutrons. Examples of different isotopes of an element are carbon 12(the most common, non-radioactive isotope of carbon) and carbon 14 (a less common, radioactive isotope of carbon). Protons and electrons have equal and opposite charge, and normally anatom has equal numbers of both. Thus, atoms are usually neutral. An ion is an atomwith extra electrons or with a deficiency of electrons, resulting in itsbeing electrically charged.
All About Atom
An ion with extra electrons is negatively charged and is called an anion; an ion deficient in electrons is positively charged and is called a cation.

Documentation If you want to read about using Atom or developing packages in Atom, the is free and available online. You can find the source to the manual in. The for developing packages is also documented on Atom.io. Installing Prerequisites. macOS Download the latest. Atom will automatically update when a new release is available.
Windows Download the latest. AtomSetup.exe is 32-bit, AtomSetup-x64.exe for 64-bit systems.
Atom will automatically update when a new release is available. You can also download atom-windows.zip (32-bit) or atom-x64-windows.zip (64-bit) from the. The.zip version will not automatically update. Run cinst Atom to install the latest version of Atom.
Linux Atom is only available for 64-bit Linux systems. Configure your distribution's package manager to install and update Atom by following the in the Flight Manual. You will also find instructions on how to install Atom's official Linux packages without using a package repository, though you will not get automatic updates after installing Atom this way. Archive extraction An archive is available for people who don't want to install atom as root.
This version enables you to install multiple Atom versions in parallel. It has been built on Ubuntu 64-bit, but should be compatible with other Linux distributions. Install dependencies (on Ubuntu): sudo apt install git gconf2 gconf-service libgtk2.0-0 libudev1 libgcrypt20 libnotify4 libxtst6 libnss3 python gvfs-bin xdg-utils libcap2. Download atom-amd64.tar.gz from the. Run tar xf atom-amd64.tar.gz in the directory where you want to extract the Atom folder. Launch Atom using the installed atom command from the newly extracted directory. The Linux version does not currently automatically update so you will need to repeat these steps to upgrade to future releases.
Building. License When using the Atom or other GitHub logos, be sure to follow the.
