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