Median response time is 34 minutes and may be longer for new subjects. The energy of electron in the ground state is â 2. Therefore an atom can only move to a new energy level if it absorbs or emits an amount of energy that exactly corresponds to the difference between two energy levels. Favorite Answer. Each of the following electron configurations represents an atom in an excited state. The sodium atom becomes A. The ground state of an atom is the state of least energy in the sense that the energy of the electrons in the orbitals cannot be lowered by moving one or more electrons to the other orbitals. eg: Consider a carbon atom whose electron configuration is the following. From the electrons in an atom, to the differing orbitals and hybridization, the ground state electron configuration sheds light on many different atomic properties. Answer Save. The ionization enthalpy is the amount of energy required to remove an electron from ground state to infinity. A free hydrogen atom in its ground state is at rest. Close to the nucleus is lower potential energy. The electron âcompromisesâ between low potential energy and low kinetic energy. Even though the species may possess some level of energy, the ground state is considered to have zero-point energy â¦
(b) If , find the kinetic energy of neutron after collision if its excites the hydrogen atom to its second excited state. That is, in a ground-state atom, all electrons are in the lowest possible energy levels. A neutron having kinetic energy collides head one with the atom. d) 1s^2 2p^4. Relevance. *Response times vary by subject and question complexity. c) 1s^2 2s^1. The ground state describes the lowest possible energy that an atom can have. Incident on the atom is a photon having an energy of 10.5 eV. An electron in a sodium atom gains enough energy to move from the second shell to the third shell. Identify the element, and write its condensed ground-state electron configuration. A hydrogen atom is in its ground state. If there is more than one possible ground state, degenerate states are said to exist. Assume that mass of both neutron and the atom is same. The ground state: Like your state of potential energy down in your basement. A ground-state atom is an atom in which the total energy of the electrons can not be lowered by transferring one or more electrons to different orbitals. Atoms may occupy different energy states. (a) 1s2 2s2 2p6 3s1 3p1 element ground state electron configuration (b) 1s2 2s2 2p6 3s2 3p4 4s1 element ground state electron configuration (c) 1s2 2s2 2p6 3s2 3p6 4s2 3d4 4p1 element ground state electron ⦠Q: Silver and ammonia may react to form Ag(NHâ)â⺠complex (Kf = 1.66 x 107). b) 1s^2 2s^2 2d^1. they occur at specific values only. What is the result? Fundamentally, understanding electron configuration leads to an understanding of the periodic table . Which ground-state electron configuration is possible for an atom in the second period? 1 Answer. The lowest possible one. c, the s orbitals have to be filled before you move onto the p. There's no 2d and you can't skip 2s and go to 2p. a) 1s^2 2s^1 2p^1. Sarah R. 1 decade ago. A negative ion B. an atom in an excited state C. a positive ion D. an atom in the ground state The energy states are discrete, i.e. In chemistry and physics, the ground state is defined as the lowest allowed energy state of an atom, molecule, or ion.In other words, the ground state represents the most stable configuration. 1 â¦
