As you learn about elements with more than eighteen electrons you will find that shell three can hold more than eight. Wait, I am looking it up in a reference. Chlorine is before argon on the periodic table, so it does not have all the electrons argon has in its ground state. Therefore the Argon electron configuration will be 1s 2 2s 2 2p 6 3s 2 3p 6. It can have either 3 or 5 valence electrons, as it can bond in the 2p and 2s orbitals outside. 22 neutrons in an average atom of Argon. Rather like a puzzle box containing exactly the right number of pieces, argon and its five cousins does not have any subatomic shortages that need to be amended by donations from other elements, and it doesn't have any extras floating around to donate in turn. 4 years ago. Argon is the third-most abundant gas in the Earth’s atmosphere, at 0.934% (9340 ppmv). You must recognize that the second principal energy level consists of both the \(2s\) and the \(2p\) sublevels and so the answer is three.

Since the outer shell electrons are fully filled, argon have no tendency to gain nor lose electrons. Find more answers. The electronic configuration of anions is assigned by adding electrons according to Aufbau's building up principle. I'm assuming you're referring to the octet rule, which states that all elements "want" to reach 8 valence electrons. 5.0 1 vote 1 vote Rate! The number of protons of an atom cannot change via any chemical reaction, so you add or subtract electrons to get the correct charge. An anion carries a negative charge and has more electrons than protons. Looking for something else? So, it has 3 electron shells, and that will be its valence shell. How many electrons does this atom have m=1 ? How many valence electrons does Argon (Ar) have? Source(s): protons element argon have: https://shortly.im/cnfo3. Therefore, argon has no electric charge (as with other elements). We will abbreviate chlorine by using the neon core. 0 0. tremble. Thanks Comments; Report Log in to add a comment Looking for something else? 18 electrons, means that there are 2 in the inner orbital, 8 in the middle orbital, and 8 valence electrons. For example, Argon [Atomic #18] has 8 valence electrons so it is considered to have a full M shell. Calculate (A) the number of electrons (B) number of protons (C) number of neutrons(D) mass number. Ti First, we see that the electron configuration is made of the core electrons (Ar) and the valence electrons (4s23d2). Neutrons do not have a net electric charge, so the number of neutrons does not matter in the calculation. Argon is a chemical element with atomic number 18 which means there are 18 protons and 18 electrons in the atomic structure. Source(s): https://shrink.im/a9iuQ. Ask your question. Oxygen is found in the sixth group, therefore it has six valence electrons. 1 See answer pi5lbibaysSwimg is waiting for your help.
