A neutral atom has the same number of electrons and protons. So the electron configuration looks like this: 1s 2 2s 2 2p 6 3s 2 3p 6 4s 2 3d 10 4p 6. The electron configuration of argon is 1s2 2s2 2p6 3s2 3p6 or [Ne] 3s2 3p6. ii) The electronic configuration of Titanium (atomic number is 22) is-. Therefore, the argon full electron configuration will be 1s2 2s2 2p6 3s2 3p6. Potassium donates the electron of the last shell to form bonds and turns into a potassium ion (K + ). The number of sub-shells will be 5 but 4s, 4p, 4d, and 4f in these four subshells it is possible to arrange the electrons of all the elements of the periodic table. Possible oxidation states are 0. The first shell of Argon has 2 electrons and the outer shell or valence shell of Argon has 8 electrons, hence, the number of valence electrons . Also, we have to make sure that the electron configuration will match the order of aufbau principle (i.e., the 1s subshell is filled first and then 2s, 2p, 3s and so on). The neutral atom chlorine (Z=17), for instance has 17 electrons. What is the noble gas configuration of argon? How many orbitals does the d sukshell have. Incorrect Number of Electrons 2. The first two electrons of argon enter the 1s orbital. The s in s block represents that all s block elements have their valence electrons in s subshell. 1s 2s 2p 3s 3p 4s 3d and so on..
