Electrons are about 0.054% as massive as neutrons, according to Jefferson Lab. What is an electron?Įlectrons are tiny compared to protons and neutrons, over 1,800 times smaller than either a proton or a neutron. Three quarks make up each proton - two "up" quarks (each with a two-thirds positive charge) and one "down" quark (with a one-third negative charge) - and they are held together by other subatomic particles called gluons, which are massless. Elements are arranged in the Periodic Table of the Elements in order of increasing atomic number. The number of protons also determines the chemical behavior of the element. The number of protons in an atom is referred to as the atomic number of that element. For example, carbon atoms have six protons, hydrogen atoms have one and oxygen atoms have eight. The number of protons in an atom is unique to each element. Protons are about 99.86% as massive as neutrons according to the Jefferson Lab. Rutherford discovered them in experiments with cathode-ray tubes that were conducted between 19. Protons are positively charged particles found within atomic nuclei. These atoms will then decay into other elements, such as carbon-14 decaying into nitrogen-14. Some atomic nuclei are unstable because the binding force varies for different atoms based on the size of the nucleus. This force between the protons and neutrons overcomes the repulsive electrical force that would otherwise push the protons apart, according to the rules of electricity. The nucleus is held together by the strong force, one of the four basic forces in nature. The protons and neutrons that make up the nucleus are approximately the same mass (the proton is slightly less) and have the same angular momentum, or spin. Virtually all the mass of an atom resides in its nucleus, according to Chemistry LibreTexts. He also theorized that there was a neutral particle within the nucleus, which James Chadwick, a British physicist and student of Rutherford's, was able to confirm in 1932. In 1920, Rutherford proposed the name proton for the positively charged particles of the atom. The nucleus was discovered in 1911 by Ernest Rutherford, a physicist from New Zealand, according to the American Institute of Physics. Adding a proton to an atom makes a new element, while adding a neutron makes an isotope, or heavier version, of that atom. Atoms always have an equal number of protons and electrons, and the number of protons and neutrons is usually the same as well. However, one proton is about 1,835 times more massive than an electron. This not only provides extended recorded times for long form productions or recording events, but gives you the added security of always having a back-up to your camera recording.Protons and neutrons have approximately the same mass.
SSD media also provides more GB per $ than camera media cards. A core principle of Atomos devices is to provide much more flexibility in terms of recording codec, resolution, and frame rate than is normally available with internal recording. With Ninja V the only limitation to how much you can record is the size of the SSD. Alongside SSDmini we also qualify a range of 2.5-inch SSDs that can be used in conjunction with the MasterCaddy III which are required when using the ATOMOS CONNECT. There is an optional SSDmini adaptor that allows CFAST II cards to be used, enabling you to recycle older media cards or align with your camera media. Measuring 8cm long, 7.5cm wide and weighing as little as 88g, the custom-built drive neatly fits into the Ninja V without impacting the overall footprint of the device. The AtomX SSDmini drives are able to record up to 150 minutes of 4K ProRes. They support up to 4TB storage, sequential read speeds of up to 550MB/s and write speeds up to 500MB/s. AtomX SSDmini drives are more compact than standard SATA SSDs and offer an affordable alternative to an SD card of similar capacity or performance. Ninja V supports removable SSD drives which provide the space and sustained performance to meet these needs. The ability to record up to 6K using advanced edit-ready formats including ProRes RAW, ProRes, and DNxHD/HR requires fast, robust, and expansive storage. Optional via ATOMOS CONNECT or AtomX SDI modules Ninja V is designed to maximize the quality of your videos and allow you to extend every aspect of your creative vision. Additionally, if you’re shooting Log footage, the ability to bypass internal compression will offer the best possible dynamic range. Ninja V can record more color information and immediately add value to your production with your existing camera rig. If the camera is able to output video via HDMI, the quality can often be preserved in a 4:2:2 8-bit or 10-bit format.
To save space and support longer recordings, many cameras record compressed 4:2:0 8-bit video internally.
