  2. Color charge - Wikipedia

    en.wikipedia.org/wiki/Color_charge

    Color charge is a property of quarks and gluons that is related to the particles' strong interactions in the theory of quantum chromodynamics (QCD). Like electric charge, it determines how quarks and gluons interact through the strong force; however, rather than there being only positive and negative charges, there are three "charges", commonly called red, green, and blue.

  3. Strong interaction - Wikipedia

    en.wikipedia.org/wiki/Strong_interaction

    Unlike the photon in electromagnetism, which is neutral, the gluon carries a color charge. Quarks and gluons are the only fundamental particles that carry non-vanishing color charge, and hence they participate in strong interactions only with each other. The strong force is the expression of the gluon interaction with other quark and gluon ...

  4. Chemical polarity - Wikipedia

    en.wikipedia.org/wiki/Chemical_polarity

    Two charges are present with a negative charge in the middle (red shade), and a positive charge at the ends (blue shade). In chemistry , polarity is a separation of electric charge leading to a molecule or its chemical groups having an electric dipole moment , with a negatively charged end and a positively charged end.

  5. Electric charge - Wikipedia

    en.wikipedia.org/wiki/Electric_charge

    Electric charge is a conserved property: the net charge of an isolated system, the quantity of positive charge minus the amount of negative charge, cannot change. Electric charge is carried by subatomic particles. In ordinary matter, negative charge is carried by electrons, and positive charge is carried by the protons in the nuclei of atoms ...

  6. Quark - Wikipedia

    en.wikipedia.org/wiki/Quark

    The pattern of strong charges for the three colors of quark, three antiquarks, and eight gluons (with two of zero charge overlapping). According to quantum chromodynamics (QCD), quarks possess a property called color charge. There are three types of color charge, arbitrarily labeled blue, green, and red.

  7. Electrostatics - Wikipedia

    en.wikipedia.org/wiki/Electrostatics

    The electrostatic field (lines with arrows) of a nearby positive charge (+) causes the mobile charges in conductive objects to separate due to electrostatic induction. Negative charges (blue) are attracted and move to the surface of the object facing the external charge. Positive charges (red) are repelled and move to the surface facing away ...

    The "red nail theory" is going viral on TikTok. Psychologists and color experts explain the science behind it, and if red nails will help you attract a partner.

  9. Electric field - Wikipedia

    en.wikipedia.org/wiki/Electric_field

    When the charges and have the same sign this force is positive, directed away from the other charge, indicating the particles repel each other. When the charges have unlike signs the force is negative, indicating the particles attract.
