The chemical element chlorine has 17 electrons, 17 protons and 18 neutrons. An atom, which is the fundamental unit of an element, contains an equal number of electrons and protons. The number of neutrons is calculated by subtracting the atomic number from the mass number.
The atomic number is the same as the number of protons while the mass number is the sum of the protons and neutrons. A chlorine atom has a mass number of 35. Subtracting 17 from 35 equals 18, which is the number of neutrons in a chlorine atom. In the periodic table, all elements are represented by their chemical symbol with the mass number written on the top-left portion and the atomic number on the bottom-left.Learn More
Nitrogen has seven electrons. Since the atomic number of an element tells how many protons and how many electrons are in that element, nitrogen has an atomic number of seven.Full Answer >
One neutral atom of iodine has 53 electrons. The number of electrons in a neutral atom corresponds to the atomic number of the element.Full Answer >
There must be at least two atoms of chlorine in a chlorine molecule. This produces what is called a diatomic molecule. The gas hydrogen also appears as a diatomic molecule.Full Answer >
A chlorine atom can form a single covalent bond, according to the University of Wisconsin chemistry department website. Chlorine atoms have seven electrons in their outer shells and can only share a single electron with another atom to fill that outer electron shell.Full Answer >
