Because the atomic number is determined by counting the number of electrons circling the nucleus, (neutrons and protons). Only "stable elements" are given atomic numbers, as unstable ones loose and gain electrons. This is based on an atoms natural state.
The number of electrons in an atom of an element is the same as the element's atomic number. The atomic number is the number of protons in the nucleus of an atom, which also equals the number of electrons in a neutral atom.
the number of electrons of an atom is the same as it's atomic number
in an atom of neutral charge, the number of electrons will be the same as the number of protons, or the atomic number.
An atom has the same number of electrons as it does protons, and the number of protons determines what element it is.
The neutral iodine atom contain the same number of electrons as protons - 53.
On average, in any atom, you will have the same number of electrons and protons.
The number of electrons should equal the number of protons, otherwise you have an ion.
False. The atom that has the same number of protons as it has electrons is a neutral atom.
The number of electrons should = the number of protons.
Protons and electrons in an atom always have the same number, which determines the atom's overall charge. The number of protons is equal to the atomic number of the element, while the number of electrons is equal to the number of protons in a neutral atom.
Lead has 82 Protons, 82 Electrons, and 125 Neutrons. It also has a melting point of 327.5 degrees C (or621.5 degrees F)
equals the total number of electrons in the orbital shells.
