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. Find more answers. Wait, I am looking it up in a reference. A. Neutrons do not have a net electric charge, so the number of neutrons does not matter in the calculation. Neutron is 1.0086652 atomic mass units. You must recognize that the second principal energy level consists of both the \(2s\) and the \(2p\) sublevels and so the answer is three. It is mostly Argon-40; small amts. It always has 18 Protons, and 18 electrons, but neutrons differ. * We see that argon is a noble gas. Because the third energy level has eight electrons and is therefore full (3s 2 3p 6) it is called a noble gas. How many protons neutrons and electrons does argon have?

Brainly User Brainly User Neutrons:22 Electrons:18 Still have questions? The number of protons of an atom cannot change via any chemical reaction, so you add or subtract electrons to get the correct charge. Still have questions? Identify the element from the electron configuration: [Ar]4s^2 3d^2. Hence, we can say that both are isoelectronic, having the same of number of neutrons. This tells you that it has 18 protons. Protons are particles in the nucleus of an atom that have a positive charge equal to +1. The electron configuration of argon is 1s22s22p63s23p6.

I'm assuming you're referring to the octet rule, which states that all elements "want" to reach 8 valence electrons. 4Looking at the periodic table, which element is a non-metal? Choose one answer. Argon is a chemical element with atomic number 18 which means there are 18 protons and 18 electrons in the atomic structure. Since Argon is a "noble gas," it already has 8 electrons, and does … As you learn about elements with more than eighteen electrons you will find that shell three can hold more than eight. Nitrogen makes up DNA both in the form of nitrogen bases and in neurotransmitters. 4 years ago. Helium, neon, and argon are all noble gases located in the last group (18th group) of the periodic table. So, Argon-40 would seem to be: 18 electrons which requires 18 protons and 22 neutrons. Since the outer shell electrons are fully filled, argon have no tendency to gain nor lose electrons. The electronic configuration of anions is assigned by adding electrons according to Aufbau's building up principle. Looking at the picture, you can see there are two electrons in shell one, eight in shell two, and eight in shell three. Source(s): https://shrink.im/a9iuQ. Also, you know it is a noble gas, so it's valence is full. Electron present in the first shell (n=1) 2n^2=2(1)^2=2(1)=2 . Proton is, I think, 1.0078252 amu. There are 2 electrons on the first energy level, 8 electrons on the second level, and 8 electrons on the third energy level. 548 views Verified answer. Therefore the Argon electron configuration will be 1s 2 2s 2 2p 6 3s 2 3p 6. Oxygen is found in the sixth group, therefore it has six valence electrons. For example, Argon [Atomic #18] has 8 valence electrons so it is considered to have a full M shell. How many core electrons does argon have? 5.0 1 vote 1 vote Rate! That means there are 18 electrons in an argon atom. 3 B. The electrons like to be in separate shells/orbitals. You have 1 free answer left. On the periodic table, argon's atomic number is 18. How many valence electrons does argon have? The outer shell of most atoms is not full. In fact, the number of valence electrons goes up by one for each step across a period until the last element is reached. Also mention the quantum numbers of the valence electron. The electron configuration for Ca 2+ is the same as that for Argon, which has 18 electrons. This full valence shell makes argon very stable and extremely resistant to bonding with other elements. Ask your question. Note. Argon is a noble gas with electronic configuration of [Ne] 3s2 3p6. Your welcome! Sep 10,2020 - Consider the argon atom .
