The Simplest Atom Is That Of The Element Hydrogen And It Cons...
The simplest atom is that of the element hydrogen and it consists merely of a single proton in a nucleus and a single electron in orbit around it. The helium atom is the next simplest atom and consists of a nucleus containing two protons and two neutrons, with two electrons orbiting around it. For an electron to be able to move1 around a nucleus, it must have a force exerted on it and pulling it towards the nucleus. This force is the electrical attractive force exerted by the positive nucleus on the negative electron.
Note:
5 For an electron to be able to move — для того чтобы электрон мог двигаться
