What is the excited state of bromine?
Therefore, the electron configuration of bromine(Br*) in excited state will be 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4px2 4py1 4pz1 5s1. The valency of the element is determined by electron configuration in the excited state. Here, bromine has three unpaired electrons.
What is the excited state of an atom?
Table of contents No headers An excited-state atom is an atom in which the total energy of the electrons can be lowered by transferring one or more electrons to different orbitals. That is, in an excited-state atom not all electrons are in the lowest possible energy levels.
What is an excited state of an atom electron configuration?
An excited state configuration is a higher energy arrangement (it requires energy input to create an excited state). Valence electrons are the electrons utilised for bonding. These are the ‘outer’ electrons (i.e. the electrons which travel furthest away from the nucleus) and the highest energy electrons.
What is the ground state electronic configuration of BR -?
Using the blocks in the periodic table we can write the electron configuration of bromine as: 1s22s22p63s23p64s23d104p5.
Which statement describes how an atom in the ground state becomes excited?
Which statement describes how an atom in the ground state becomes excited? The atom absorbs energy, and one or more electrons move to a higher electron shell.
Which electron configuration represents an excited state for a potassium atom?
Which electron configuration represents an excited state for a potassium atom? An atom in an excited state has an electron configuration of 2-7-2. Identify the electron configuration of this atom in the ground state. What is the total number of valence electrons in a calcium atom in the ground state?
What is ground state and excited state of an atom?
Definition. Ground State: Ground state refers to the state in which, all electrons in a system (an atom, molecule or ion) are in the lowest possible energy levels. Excited State: Excited state is any state of the system that has a higher energy than the ground state.
What is the excited state of phosphorus?
In an excited state, electrons are excited from lower energy level to higher energy level. Here in phosphorus in an excited state an electron is excited from 3s to 3d orbit. Now, the electronic configuration of phosphorus in excited state is [Ne]3s13p33d1.
Which electron configuration represents a potassium atom in an excited state?
Which is more stable BR or BR -?
Answer. Br2 is more stable in liquid form because in diatomic form 2 bromines will be acquiring a stable configuration(8 electrons).
What is the ground state electron configuration of bromine?
Ground state electron configuration of bromine is 1s 2 2s 2 2p 6 3s 2 3p 6 3d 10 4s 2 4p 5. In the bromine ground-state electron configuration, five electrons of the 4p orbital are located in the 4p x (2), 4p y (2) and 4p z sub-orbitals.
How many electrons does bromine (Br) have?
The atomic number of bromine (Br) is 35. That is, the number of electrons in bromine is thirty-five. Therefore, the bromine atom will have two electrons in the first shell, eight in the 2nd orbit, eighteen electrons in the 3rd shell, and the remaining seven electrons will be in the fourth shell.
What is the valency of bromine?
The valency of the element is determined by electron configuration in the excited state. Here, bromine has three unpaired electrons. So in this case, the valency of bromine is 3. The electron configuration of bromine shows that the last shell of bromine has seven electrons.
What is the electron configuration of BR?
Electron Configuration of Bromine (Br) [Complete, Abbreviated, Uses Electrons have a specific form of distribution (or configuration) in every atom, even Bromine. Some are hard to memorise (or predict), so what is the electron configuration of an atom of Br? In the case of Bromine the abbreviated electron configuration is [Ar] 3d10 4s2 4p5.
