Web3 dec. 2024 · An atom has a central nucleus. This is surrounded by electrons arranged in shells. The nucleus is tiny compared to the atom as a whole: the radius of an atom is about 0.1 nm (1 × 10-10 m)... WebAntiprotonic helium is a three-body atom composed of an antiproton and an electron orbiting around a helium nucleus. It is thus made partly of matter, and partly of antimatter. The atom is electrically neutral, since both electrons and antiprotons each have a charge of −1, whereas helium nuclei have a charge of +2.

The electron had already been discovered by J.J. Thomson. Knowing that atoms are electrically neutral, J.J.Thomson postulated that there must be a positive charge as well. In his plum pudding model, Thomson suggested that an atom consisted of negative electrons randomly scattered within a sphere of positive charge. Ernest Rutherford late… message screen stacktrace
