According to the older shell atomic model, electrons occupy several levels from the first shell nearest the nucleus, K, through the seventh shell, Q, farthest from the nucleus. 0 10. Since K loses one electron (1 negative charge) it is no longer neutral; it now has a +1 charge. Hence answer is option C Periods 1 to 3: Subshell Electronic Configuration Key Concepts. The K shell contains a 1s subshell hence it can carry 2 electrons, the L shell has 2s and 2p, … Favorite Answer. There are 8 elements in Period 2 of the periodic table: The atoms of elements in Period 1 filled, or completed, the first energy level, or K shell. That is, for an atom to be neutral (no overall charge), the number of negative charges (electrons) must be equal to the number of positive charges (protons). In the diagram below, the black circle represents the nucleus of the atom, and each circle represents the boundary of an electron shell. Krypton Electronic configuration. 2. By assuming that an atom will exist in its lowest possible energy state, we can now add the electrons one by one to the energy levels (shells). Kazi Ashiq Iqbal Nov 16, 2015 2,8,8,1. The electronic configuration of K is 1s22s22p63s23p64s1. The number of electrons in the second energy level (L shell) is separated from those in the first by a comma when writing the electron configuration (electronic configuration). For this example, we will use the iodine atom. For atoms with more than 3 electrons, we can continue adding electrons to the second energy level or L shell until it reaches its maximum capacity of 8 electrons: In writing the electron configuration for Potassium the first two electrons will go in the 1s orbital. If an atom has 2 electrons, then both the first and second electron occupy the 1st energy level (K shell): The electron (electronic) configuration of the atom is 2. Electron Configurations are an organized means of documenting the placement of electrons based upon the energy levels and orbitals groupings of the periodic table.. Recent developments in chemistry written in language suitable for students. 1s2 2s22p63s23p6. The alkali earth metals (group 2), such as, Mg or Sr lose two e-'s to attain the configuration of Ne.
