The KLMN electron configuration of Argon is 2, 8, 8 each number referring to the electrons in the shells or energy levels of the atom. Electron present in the first shell (n=1) 2n^2=2(1)^2=2(1)=2 . Note. In fact, the number of valence electrons goes up by one for each step across a period until the last element is reached. Add your answer and earn points. 18 electrons, means that there are 2 in the inner orbital, 8 in the middle orbital, and 8 valence electrons. 6 c. 7 d. 8 You'll also have 83 argon atoms, and 667 calcium atoms. It's mass, 40, minus 18 (electrons) equals 22 (neutrons). Therefore, argon has no electric charge (as with other elements). So, it has 3 electron shells, and that will be its valence shell. You must recognize that the second principal energy level consists of both the \(2s\) and the \(2p\) sublevels and so the answer is three. i need to know the number of protons,neutrons,and electrons the element argon has. Brainly User Brainly User Neutrons:22 Electrons:18 Still have questions? Argon's complete octet of electrons indicates full s and p subshells. Before 1962, argon and the other noble gases were considered to be chemically inert and unable to form compounds; however, compounds of the heavier noble gases have since been synthesized. Only the atoms in the elements of Group or Family 18 on the Periodic Table have full outer shells. Therefore the Argon electron configuration will be 1s 2 2s 2 2p 6 3s 2 3p 6. You have 1 free answer left. Shell number one can only hold 2 electrons, shell two can hold 8, and for the first eighteen elements shell three can hold a maximum of eight electrons.

Have students complete the energy level model for argon in their periodic table. Nitrogen makes up DNA both in the form of nitrogen bases and in neurotransmitters. Since the outer shell electrons are fully filled, argon have no tendency to gain nor lose electrons. s. Log in for more information. See answers (1) Ask for details ; Follow Report Log in to add a comment Answer 5.0 /5 2 +2 taffy927x2 and 2 others learned from this answer 10 core electrons are in argon. The protons and electrons cancel each other out because protons produce a positive charge, electrons a negative charge, and they have the same amount. I'm assuming you're referring to the octet rule, which states that all elements "want" to reach 8 valence electrons. Proton is, I think, 1.0078252 amu. 4 years ago. Neutron is 1.0086652 atomic mass units. Unfortunately, I do not have the information about neutrons. If neutral, there would have to be 18 protons for the 18 electrons. An anion carries a negative charge and has more electrons than protons. 548 views Verified answer. This tells you that it has 18 protons. Choose one answer. * The p orbital can hold a maximum of 6 electrons. It is mostly Argon-40; small amts. 40-18 is 22. 0 0. Share 4. Your welcome! 0 0. tremble. In the third shell, it holds a total of 2+6=8 electrons, so it has 8 valence electrons. How many protons neutrons and electrons does argon have? Asked 10/14/2016 9:05:18 AM. Explain that argon has 18 protons and 18 electrons. So, Argon-40 would seem to be: 18 electrons which requires 18 protons and 22 neutrons. We are suppose to do:-An isotope of that atom-An ion of that atom, with a positive charge. The electron configuration of argon is 1s22s22p63s23p6. The electronic configuration of anions is assigned by adding electrons according to Aufbau's building up principle. How many electrons does this atom have m=1 ? How many valence electrons does boron have? Get an answer. 1 See answer pi5lbibaysSwimg is waiting for your help. Source(s): protons element argon have: https://shortly.im/cnfo3. The number of protons of an atom cannot change via any chemical reaction, so you add or subtract electrons to get the correct charge. As you learn about elements with more than eighteen electrons you will find that shell three can hold more than eight. The outer shell of most atoms is not full. Also mention the quantum numbers of the valence electron. Rate! 2 Answers/Comments. Calculate (A) the number of electrons (B) number of protons (C) number of neutrons(D) mass number. The electron configuration for Ca 2+ is the same as that for Argon, which has 18 electrons. Wait, I am looking it up in a reference. For example, boron (B) has an atomic number of 5, therefore it has 5 protons and 5 electrons. * Electron configuration: [Ne] 3(s(2)) 3(p(6)). Nitrogen has either 3 or 5 valence electrons and is on the periodic table at the top of Group 15. Since Argon is a "noble gas," it already has 8 electrons, and does … How many core electrons does argon have? argon has … Oxygen is found in the sixth group, therefore it has six valence electrons. Argon is a noble gas with electronic configuration of [Ne] 3s2 3p6. … Since the 3s if now full we'll move to the 3p where we'll place the remaining six electrons. Argon is the third-most abundant gas in the Earth’s atmosphere, at 0.934% (9340 ppmv). Find more answers . 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. of -36 and -38. Neon, with its configuration ending in \(2s^2 2p^6\), has eight valence electrons. | EduRev JEE Question is disucussed on EduRev Study Group by 513 JEE Students. There are 2 electrons on the first energy level, 8 electrons on the second level, and 8 electrons on the third energy level. Also, you know it is a noble gas, so it's valence is full. For the isotope, I did Argon 40, which has 18 protons, 22 nuetrons, and 18 electrons. It can have either 3 or 5 valence electrons, as it can bond in the 2p and 2s orbitals outside. :) … Thanks Comments; Report Log in to add a comment Looking for something else? 8 Argon is a noble gas with an electron configuration of [Ne]3s^2\\3p^6. Anonymous. Chlorine is before argon on the periodic table, so it does not have all the electrons argon has in its ground state. Looking at the picture, you can see there are two electrons in shell one, eight in shell two, and eight in shell three. This means that if you have 1000 atoms of 40 K, 1.2 billion years later you'll have 500, and 1.2 billion years after that you'll have 250. 0 b. 3 B. Unlock answer. If there are more electrons than a shell can hold, a new shell starts. Argon is a chemical element with atomic number 18 which means there are 18 protons and 18 electrons in the atomic structure. For the best answers, search on this site https://shorturl.im/axFwP. It has five electrons in its outer shell, most of its compounds are trivalent. How many valence electrons does argon have? We will abbreviate chlorine by using the neon core. Hence, we can say that both are isoelectronic, having the same of number of neutrons. On the periodic table, argon's atomic number is 18. For example, Argon [Atomic #18] has 8 valence electrons so it is considered to have a full M shell. More about the history and places to find argon. 4Looking at the periodic table, which element is a non-metal? * We see that argon is a noble gas. I am doing a project on the element Argon.
