Who Discovered that atoms contain negatively charged particles called electrons?
In 1897, a British scientis named J.J. Thomson.
Does the troposphere contain electrically charged particles?
yes
What is a stream of eletricically charged particles sent out by the crona called?
A stream of electrically charged particles that is sent out by the crona is called a cosmic ray. Such rays contain very high levels of radiation.
What does nuclei contain?
Nuclei contain protons (positively charged particles) and neutrons (no charge). numbers of neutrons and protons makes up mass of atom.
What is contained in an atom?
In an atom there are 3 types of particles!!! Protons:Positively charged paricles Electrons:Negatively charged paricles Neutrons:Neutrally charges particles or particles having no charge
What can be made of one atom?
Positively charged proton Negatively charged electron Neutrally charged neutron Those are fundemental elementary particles and all atoms which make up over 100+ elements in the universe all contain these three fundamental elementary particles.
Scientists who discovered protons?
Protons were discovered when the nucleus of atoms were discovered. Electrons were already known about, so when the nucleus was discovered, it was known that it had to contain positively charged particles: protons. The nucleus was discovered by Ernest Rutherford by shooting alpha particles (helium nuclei, basically helium without the electrons) at a thin sheet of gold. Most of the alpha particles went straight through, but some if them were scattered. Rutherford deduced that these particles had hit something in the foil that didn't take up a large percentage of space: the nuclei of the gold atoms.
Does nonelectrolytes conduct a current when made into a solution?
No. Electrolyte solutions contain ions, or charged particles, which are able to carry a current.
What is a materials that does not let electricity flow through it?
Many materials are packed full of easily-movable charged particles. Any material that does not contain easily-movable charged particles is called an "insulator". Charged particles do not flow through an insulator. Common insulators are rubber, plastic, nylon and air. (Rubber, plastic, and nylon are packed full of charged particles, but those particles are "bound" into a solid, unmoving configuration. The particles in air are easily-movable, but they are practically all uncharged particles -- and also there are so few of them that air is mostly empty space compared to solids).
How does earth's magnetic field help human beings?
The Earth's magnetic field deflects solar winds which contain charged particles. These particles would be fatal to human beings.
How are can be atoms neutral if they contain charged particles?
the no of positive charges are equal to negative charges (protons = electrons) in any neutral atom.
What are the other particles of atom?
Atoms contain three main particles. Electrons- which are negatively charged and swarm around the nucleus. Protons- which are positively charged, and are tightly packed in the nucleus. Neutrons- which are neutrally charged and are packed together with the protons in the nucleus of the atom. They are held there by strong nuclear force. You're welcome.
