Answer Save. Median response time is 34 minutes and may be longer for new subjects. A free hydrogen atom in its ground state is at rest. Identify the element, and write its condensed ground-state electron configuration. The electron “compromises” between low potential energy and low kinetic energy. Which ground-state electron configuration is possible for an atom in the second period? Close to the nucleus is lower potential energy. 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. That is, in a ground-state atom, all electrons are in the lowest possible energy levels. Incident on the atom is a photon having an energy of 10.5 eV. What is the result? Q: Silver and ammonia may react to form Ag(NH₃)₂⁺ complex (Kf = 1.66 x 107). Each of the following electron configurations represents an atom in an excited state. The ground state: Like your state of potential energy down in your basement. *Response times vary by subject and question complexity. c) 1s^2 2s^1. The energy of electron in the ground state is − 2. 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. The sodium atom becomes A.
(a) Find minimum value of so that this collision can be inelastic. Relevance. 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. If there is more than one possible ground state, degenerate states are said to exist.
(b) If , find the kinetic energy of neutron after collision if its excites the hydrogen atom to its second excited state. Fundamentally, understanding electron configuration leads to an understanding of the periodic table . Favorite Answer. An electron in a sodium atom gains enough energy to move from the second shell to the third shell. b) 1s^2 2s^2 2d^1. d) 1s^2 2p^4. A neutron having kinetic energy collides head one with the atom. 1 Answer. Assume that mass of both neutron and the atom is same. (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 … 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. Sarah R. 1 decade ago. The ground state describes the lowest possible energy that an atom can have. a) 1s^2 2s^1 2p^1. Even though the species may possess some level of energy, the ground state is considered to have zero-point energy … they occur at specific values only. A hydrogen atom is in its ground state. The lowest possible one. 1 … From the electrons in an atom, to the differing orbitals and hybridization, the ground state electron configuration sheds light on many different atomic properties. The ionization enthalpy is the amount of energy required to remove an electron from ground state to infinity. A negative ion B. an atom in an excited state C. a positive ion D. an atom in the ground state 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. eg: Consider a carbon atom whose electron configuration is the following. The energy states are discrete, i.e. Atoms may occupy different energy states. Head one with the atom new subjects atom whose electron configuration leads an.
