2,8,8,1 electron configuration

Answer Save. K 2, 8, 8, 1 i. I assume you mean that orbital 1 has 2 electrons, orbital 2 has 8 and orbital 3 has 8. The electron configuration states where electrons are likely to be in an atom. The first twenty elements 1 2 13 14 15 16 17 18; 1: hydrogen 1 : helium 2: 2: lithium 2.1: beryllium 2.2: boron 2.3: carbon Use the element blocks of the periodic table to find the highest electron orbital. What is the atomic number of this element? Hence, the electronic configuration of potassium is 2, 8, 8, 1 and not 2, 8, 9. What is the valency of this element? Electronic configuration of 'X' is 2, 8, 8, 2. If you don’t have a chart, you can still find the electron configuration. K 1s2 2s2 2p6 3s2 3p6 4s1 (the numbers at the end are supposed to be in superscripts, to represent the number of valence electrons in the orbital) Or. Why is it that the electron configuration for calcium is 2, 8, 8, 2 and not 2, 8, 10? ii. What are the rules that govern the 3rd energy level? The electron configuration (electronic configuration) of an atom of sulfur is 2,8,6 An atom of sulfur has 2 electrons in the first energy level (K shell), 8 electrons in the second energy level (L shell) and 6 electrons in the third energy level (M shell). Is calcium special? v. With which of the following elements would this element resemble? (c) The valency of X is 2 because it can acquire stable gas configuration by losing 2 electrons. What is the group of this element? The electron configuration for potassium is . 2. iv. As an approximate rule, electron configurations are given by the Aufbau principle and the Madelung rule. An element has its electron configuration as 2,8,2. Relevance. For which other elements does the 3rd energy level only hold 8 electrons and not 18? According to octet rule, the outermost shell of an atom can accommodate maximum 8 electrons (except K shell which can accommodate maximum 2 electrons). The electronic configuration of an element T is 2,8,8,1. The electronic configuration of an element is 2, 8, 8, 1 (i) State its group number and period number in the modern periodic table (ii) State whether this element is a metal or a non-metal Give reason for the justification of your answer in each case - Science - Periodic Classification of Elements 3 Answers. - 2268208 An up-to-date periodic table with detailed but easy to understand information Now answer the following questions. To which period does this element belong? (b) Since X has 2 valence electrons, so it belongs to group no. iii. The electronic configurations of the elements in group 1: The atoms of all group 1 elements have similar chemical properties and reactions because they all have one electron in their outer shell. (a) X belongs to period 4 because it has 4 energy shells.
