The number of electrons in an atom of an element is equal to its atomic number, which is the number of protons in its nucleus. For example, if the atomic number of the element is 6, it contains 6 electrons. In a neutral atom, the number of electrons matches the number of protons, ensuring overall electrical neutrality.
Argon is a non metal element. There are 18 electrons in a single atom.
Chlorine is a metal element. There are 17 electrons in a single atom.
Platinum is a metal element. There are 78 electrons in a single atom.
5 valence electrons.
12
Fluorine is the name of the element and has 9 electrons. Fluoride is the name of the halide ion, carries a 1- charge and has 10 electrons.
Lead is a metal element. There are 82 electrons in a single atom.
That depends on the number of protons. It also depends whether the atom has gained or lost electrons to form an ion. Carbon is element number 6; it has 6 protons and 6 electrons. Lead is element number 82; it has 82 protons and 82 electrons.
The neutral atom of promethium contain 61 electrons.
No such element
The very inner shell of an atom is the 1st shell and can only contain 2 electrons.
Tungsten is a metal element. There are 74 electrons in a single atom.
Gold is a metal element. There are 79 electrons in a single atom.
The atom of a chemical element contain protons, neutrons and electrons; the number is specific for each isotope.
Depends on what element this atom is.
the element Ir has 77 electrons
Fluorine is a non metal element. There are 9 electrons in a single atom.
