what is the difference between an atom in the ground state and an atom in an excited state brainly?
481089
The atom in the ground state has less energy and is less stable than the atom in an excited state. ... The atom in an excited state has one more electron than the atom in the ground state.
849621
The number of protons in the nucleus of the atom is equal to the atomic number (Z). The number of electrons in a neutral atom is equal to the number of protons.

Which electron configuration represents an atom of chlorine in an excited state? (2) 2-8-6-1 this is the excited state of Chlorine, on the periodic table the ground state is 2-8-7. The excited state electron configuration is showing an electron leaving one energy level and moving up to a higher level.

One important difference between AAS and UV-visible spectrophotometer to notice is that in AAS a sample must be atomized for the observation of atomic lines, and this is frequently accomplished by a flame. Another major difference between them lies in the radiation source.

For example, the ground state electron configuration of oxygen is 1s2 2s2 2p4. The excited state electron configuration shows when an electron is excited and jumps into a higher orbital.

Orbitals can hold a maximum of two electrons. The main difference between atomic and molecular orbital is that the electrons in an atomic orbital are influenced by one positive nucleus, while the electrons of a molecular orbital are influenced by the two or more nuclei depending upon the number of atoms in a molecule.

Heating an atom excites its electrons and they jump to higher energy levels. When the electrons return to lower energy levels, they emit energy in the form of light. ... Every element has a different number of electrons and a different set of energy levels. Thus, each element emits its own set of colours.

Terms in this set (28) What is the difference between protons, neutrons, and electrons? protons are positive, neutrons are neutral, and electrons are smaller and negative. What do atoms of an element have in common with other atoms of the same element?

The difference between absorption and emission spectra are that absorption lines are where light has been absorbed by the atom thus you see a dip in the spectrum whereas emission spectra have spikes in the spectra due to atoms releasing photons at those wavelengths.

When excitation occurs the orbital electron is promoted to a higher energy level within the atom, but when ionisation occurs the electron receives enough energy to completely leave the atom. (b) An atom can also become excited by the absorption of photons.

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. That is, in a ground-state atom, all electrons are in the lowest possible energy levels. eg: Consider a carbon atom whose electron configuration is the following.

The number of protons within the atom's nucleus is called atomic number and is equal to the number of electrons in the neutral (non-ionized) atom. Each atomic number identifies a specific element, but not the isotope; an atom of a given element may have a wide range in its number of neutrons.

On average, the 2s electrons will be at a slightly greater distance from the nucleus than the 2p electrons. However, the 2s electrons have a higher probability of being closer to the nucleus due to the inner peak. As a result, the 2s orbital will lie lower in energy than the 2p orbital in multi-electron atoms.

The main difference between Proton, Neutron and Electrons can be found in their charges. Protons are positively charged and neutrons are neutral whereas electrons are negatively charged. Protons are found in the nucleus of the atom, and they reside together with neutrons. ... Protons are positively charged.

No. An ion has no ground State as rhey are in the lowest possible energy level. 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.

The single most important difference between these elements is the number of protons each one contains in its nucleus. The number of protons an atom contains dictates how many electrons it will have. It is the arrangement of electrons around an atom's nucleus that determines that atom's chemical properties.

With atomic spectroscopy you can found the nature and the amounts of a given element in your sample whereas, molecular spectroscopy concerns all the interaction of electromagnetic waves with the matter and gives you much more details than atomic spectroscopy especially about chemical functions, structure of chemical ...
