At a pressure of 200atm, water's melting point is approximately what and its boiling point is approximately what. Its electronic configuration is 1s22s22p63s23p6 4s2 instead of 1s22s22p63s23p6 3d14s1. The actual electron configuration of calcium is 1s2 2s2 2sp6 3s2 3p6 4s2. You can discover exactly why if you study the rules for orbital quantum numbers  • The 2 stands for the 1s2. Thus, M shell can hold a maximum of 18 electrons, however if it is the valence shell, the it cannot hold more than 8 electrons. Kindly Sign up for a personalized experience. Is calcium special?

The concept of electronic configuration that you study at this stage is just a rough idea about how electrons are arranged in an atom. Continue Reading. (a) X belongs to period 4 because it has 4 energy shells. Here the number of valence electrons is 2. As the energy of 3d orbital is higher than 4s, the last two electrons in calcium get accomadated in 4s energy level instead of 3d. We write the elecronic configuration of Calcium as 2,8,8,2 and not 2,8,10 but as the atomic nos. shown at AS e.g 1s2, 2s2, 2p6, 3s2, 3p6 4s2. 1. Get answers by asking now. because calcium is in the alkaline metal family, it has to have 2 valence electrons. toppr. The rule that the valence shell cannot hold more than 8 electrons will also become clearer once you become familiar with the concept of subshells and orbitals. Please answer in detail as i have not studied detailed electronic configuration, you know 2s, 2p etc, i don't know these things. Performance & security by Cloudflare, Please complete the security check to access. Afraid of a subject or a topic? Why the electronic configuration of calcium is 2,8,8,2 why not 2,8,10 as 3rd shell can holds 18 electrons - 20445507 As calcium has 20 electrons the configuration is 2,8,8,2. of copper is written as 2,8,18,1. why explain appropriate reason and example The actual electron configuration of calcium is 1s2 2s2 2sp6 3s2 3p6 4s2. After looking closely it actually relates to the electron config. Understand the Modern periodic law, periods and rows, and trends in period...

Queries asked on Sunday & after 7pm from Monday to Saturday will be answered after 12pm the next working day. n = 4 shell has 2 electrons. Completing the CAPTCHA proves you are a human and gives you temporary access to the web property. Should I call the police on then? For which other elements does the 3rd energy level only hold 8 electrons and not 18? Performance & security by Cloudflare, Please complete the security check to access. Electronic configuration of 'X' is 2, 8, 8, 2. This is because of Afbau’s principle which states that electrons fill orbitals starting at the lowest available (possible) energy levels before filling higher levels (e.g. Answer: Q10.

The d orbital only becomes available for elements with atomic numbers higher than calcium. What are the rules that govern the 3rd energy level? Still have questions? Completing the CAPTCHA proves you are a human and gives you temporary access to the web property. All rights reserved. It is because of this order (in which the atomic orbitals are filled) that the electronic configuration of of calcium is 2, 8, 8, 2 and not 2, 8, 9, 1 or 2, 8, 10. We write the elecronic configuration of Calcium as 2,8,8,2 and not 2,8,10 but as the atomic nos. Find the valency of the element? The valency of the element is decided by the number of valence electrons. n = 1 shell has 2 electrons. Therefore the valency is 2. If you are at an office or shared network, you can ask the network administrator to run a scan across the network looking for misconfigured or infected devices. Copyright Notice © 2020 Greycells18 Media Limited and its licensors. The electronic configuration of calcium is 2, 8, 8, 2. Answer. The Questions and Answers of The electronic configuration of Ca(20) isa)2, 8,10b)2, 8, 8, 2c)2, 8, 2, 8d)2, 2, 8, 8Correct answer is option 'B'. n = 2 shell has 8 electrons. Why is it that the electron configuration for calcium is 2, 8, 8, 2 and not 2, 8, 10? Your IP: 22.214.171.124 What is the IUPAC name for ch3-ch2-c(double bond o)-ch3?
