Electrons are located in the electron cloud - the outermost portion of the atom. The electron cloud accounts for about 99% of the space taken up by the atom, yet less than 1% of the mass.
A good way of thinking about this is in terms of a football field. Imagine the nucleus of the atom was the size of a blueberry. Place the blueberry in the middle of a football field, and that is the size of the electron cloud in comparison to the nucleus. As you see, the atom is mostly empty space with electrons floating around within.
Within the electron cloud, electrons are organized into levels, sublevels, orbitals, and spins. Outermost electrons bond with other atoms. The placement of electrons within an electron cloud determines the stability and chemical properties of an element.
A nitrogen atom has seven electrons.
The electrons farthest away from the nucleus are the valence electrons of an atom.
Helium atom has 2 electrons.
There are 33 electrons in an Arsenic atom.
A single atom of Carbon has 6 electrons, with 4 in the outer shell which it will use to react
Yes, electrons do spin in an atom.
valence electrons
The outer electrons of an atom are called valence electrons.
An atom with 2 electrons would be helium, an atom with 8 electrons would be oxygen, and an atom with 6 electrons would be carbon.
The flow of electrons from atom to atom is an electrical current.
electronegativity
There are 17 electrons i a neutral atom of chlorine.
