opposites attract, likes repel.
A negative charge attracts a positive charge and repels a negative charge. OPPOSITES ATTRACT ;)
When a material gains electrons, it becomes negatively charged. This is because it now has more negatively charged electrons than positively charged protons. The excess electrons will repel each other and attract positive charges in the environment.
no, it is negatively charged
When negatively charged electrons move from one material to another, the overall charge on each material can become more positive or negative depending on the relative movement of electrons. For instance, if electrons leave a material, it can become positively charged, and if electrons are gained, the material can become negatively charged. This transfer of electrons can result in materials having different net charges.
No, they are negatively charged.
positive protons
Nitrogen is negatively charged.
Negatively charged polysaccharides
Electrons are negatively charged.
If you move the material near the negative acetate strip and they repel each other, the material negatively charged. If they move towards each other, it is positively charged. If you move the material near the positive rod and they attract, the material is negatively charged. If they repel, it is positively charged. This is because opposite charges attract and same charges repel.
It should normally be neutral, that is, it should not have a significant charge, positive or negative.
It is a negatively charged object
