Orbit at which the electrons circulate Orbit at which the electrons circulate, can be found at various distances from the kernel and create a few layers. Each layer is only a certain number of electrons. For example, the copper atom has 5 layers: the first layer 2 electrons circulate in the second and third - at 8 in the fourth - 10 and the fifth electron 1. Strength electron by the kernel depends on the layer in which the electron is - the closer the kernel, the electron is strongly attracted. Are the least attracted electrons circulating in the furthest layer. From the amount of electrons in the layer furthest, chemical properties are determined by the atom. Outer electrons, as the least attracted, may under the influence of different reasons to leave the atom. For the loss of electron equilibrium is disturbed electric atom and atom becomes electrically positive. However, if the outer layer of the press is free electron, the electron and a preponderance of the atom becomes electrically negative. Atoms or molecules with a negative or positive charge are called ions. Each atom has an electronic equivalent of the proton. The more so the element has the electron, the more the kernel is the proton.
