We are suppose to do:-An isotope of that atom-An ion of that atom, with a positive charge. * In argon we see that the orbitals are completely filled. Neutrons do not have a net electric charge, so the number of neutrons does not matter in the calculation. A. The number of protons of an atom cannot change via any chemical reaction, so you add or subtract electrons to get the correct charge. 4 years ago. 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. How many protons neutrons and electrons does argon have? Because the third energy level has eight electrons and is therefore full (3s 2 3p 6) it is called a noble gas. If there are more electrons than a shell can hold, a new shell starts. * Electron configuration: [Ne] 3(s(2)) 3(p(6)). 1 See answer pi5lbibaysSwimg is waiting for your help. * The p orbital can hold a maximum of 6 electrons. In the third shell, it holds a total of 2+6=8 electrons, so it has 8 valence electrons. :) … There are 2 electrons on the first energy level, 8 electrons on the second level, and 8 electrons on the third energy level. That means there are 18 electrons in an argon atom. For example, boron (B) has an atomic number of 5, therefore it has 5 protons and 5 electrons. Unlock answer. 40-18 is 22. 0 0. tremble.

Helium, neon, and argon are all noble gases located in the last group (18th group) of the periodic table. How many valence electrons does nitrogen have? 22 neutrons in an average atom of Argon. So, it has 3 electron shells, and that will be its valence shell. Also, you know it is a noble gas, so it's valence is full. 8 Argon is a noble gas with an electron configuration of [Ne]3s^2\\3p^6. | EduRev JEE Question is disucussed on EduRev Study Group by 513 JEE Students. Since Argon is a "noble gas," it already has 8 electrons, and does … 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. Therefore the Argon electron configuration will be 1s 2 2s 2 2p 6 3s 2 3p 6. 5.0 1 vote 1 vote Rate! The protons and electrons cancel each other out because protons produce a positive charge, electrons a negative charge, and they have the same amount. Chlorine is before argon on the periodic table, so it does not have all the electrons argon has in its ground state. Oxygen is found in the sixth group, therefore it has six valence electrons. a. You must recognize that the second principal energy level consists of both the \(2s\) and the \(2p\) sublevels and so the answer is three. You have 1 free answer left. 6 c. 7 d. 8 of -36 and -38. How many valence electrons does silicon (Si) have? Since the 3s if now full we'll move to the 3p where we'll place the remaining six electrons. The electrons like to be in separate shells/orbitals. * We see that argon is a noble gas. Add your answer and earn points. Therefore, an element in a neutral state will have the same number of protons and electrons. Anonymous. How many electrons does this atom have m=1 ?
