Charged particle

In physics, a charged particle is a particle with an electric charge. It may be an ion, such as a molecule or atom with a surplus or deficit of electrons relative to protons. It can be the electrons and protons themselves, as well as other elementary particles, like positrons. It may also be an atomic nucleus devoid of electrons, such as an alpha particle, a helium nucleus. Neutrons have no charge, so they are not charged particles unless they are part of a positively charged nucleus. Plasmas are a collection of charged particles, atomic nuclei and separated electrons, but can also be a gas containing a significant proportion of charged particles. Plasma is called the fourth state of matter because its properties are quite different from solids, liquids and gases.

    Weekend Crossword: When Earth, Saturn, and Jupiter put on their own light show

    Gulf News 22 Oct 2021
    By generating a constant stream of charged particles, or plasma, the sun creates a kind of solar wind that slams into the invisible magnetic field surrounding the Earth. Its solar particles collide with gas atoms in the Earth's upper atmosphere, and ‘excite’ them with extra energy, which then gets released as light....

    Wearable air purifiers: What are they, and do they work?

    Digital Trends 21 Oct 2021
    They may create an electrical charge to attract and trap particles. They may also use a variety of filters, including HEPA filters, to hold those unwanted particles and prevent them from getting back into the air. Air purifiers will often use a fan or circulation device to pull particles in so that they can contain them....

They consist of scintillators and gaseous detectors that can detect charged and neutral particles....

    Meet Zephyr: Razer’s crazy RGB N95 mask gets real

    PC World 21 Oct 2021
    But given the mask’s silicone seal (which should offer a far better seal than surgical masks) and its N95 filters (which also filter smaller particles by creating an electro-static charge), we’d hazard it gives you far more protection than the old T-shirts you’ve been wearing over your face....
