What is the difference between a neutral atom an ion and an excited atom?

A neutral atom is an atom with an equal number of electrons and protons without any additional energy. An excited atom has electrons that have absorbed energy and moved up to another layer. Ions are atoms that have a different number of electrons from the neutral atom.

What is the difference between emission and absorption?
Emission is something be spread out, while absorption is something being taken in.
When an electron in an atom moves from a lower energy state to a higher state?
An electrons moves from lower energy to higher energy when it is excited.
Explain why ionized calcium can form absorption lines but ionized hydrogen can not.?
every atom can absorb light at different specific wavelengths (a useful fingerprint), these wavelengths correspond to the amount of energy it takes to move the atom's electrons from their ground state to an excited state, this is the cause of absorption lines. the atom will soon emit the light again (at the same wavelength, as the electron moves from excited to ground states), but in a random direction, this is the source of emission lines. an ion is an atom that has lost one or all of its electrons. in the case of a calcium ion, there are still some electrons present, atomic hydrogen has only one electron, so once it becomes ionised there are no electrons to create absorption lines.
Is it true stars like the sun burn hydrogen producing helium?
All stars fuse hydrogen into helium - the slight difference in atomic weight between 4 hydrogen atoms and one helium atom, is given off as radiation.
Is the sun inorganic energy?
No. The energy of the sun is derived from nuclear fusion, proportionate to the difference in mass of the old and newly created atom(s).
What is the difference in mass between a neutral deuterium atom and a neutral tritium atom?
1.6749x10-24
Why an excited atom is electrically neutral?
Even an electron excited to a higher than normal energy level remains sufficiently close to the nucleus of its atom that the atom as a whole remains neutral.
What is the ground state electronic configuration of a neutral atom of element X?
It is the electron configuration of a neutral, not excited atom.
What is the difference between neutron and a electorns?
The difference between neutron are neutral, and electrons have a negative change too them. Neutron is a neutral particle that exists in the nucleus of an atom. The year when the neutron was founded was 1932.
What is HTE difference between an atom in the ground state and an atom in an excited state?
Atom in the ground state is stable but atom in excited state is not stable the main reason for this is their energies.Atoms in excited state has more energy so they undergo chemical reaction so they are not stable but atoms in ground state has less energy than the excited state so they dont undergo chemical reaction.
The difference between an electrically neutral atom and an ion is that?
The difference is in the number of electrons they have. In a neutral atom, the number of electrons is the same as the number of protons (or atomic number) for that element. In an ion, this is not the case, with either less electrons (an overall positive charge) or more electrons (an overall negative charge) than he neutral atom
What happens when the electrons relax?
As excited electrons drop back to lower energy levels in the atom, photons having the energy of the difference between the two electron energy levels are emitted from the atom.
What is the number of electrons in a neutral atom equals?
In a neutral atom the number of electrons is equal to the number of protons. The opposite charge between protons and electrons is what allows for a neutral atom.
What is the difference between atomic mass?
What is the difference between the ground state of an atom and excited state of an atom?
An atom is in its ground state when all the electrons in the atom occupy orbitals that result in the minimum chemical potential energy for the atom as a whole. An excited atom is one that stores (at least for a brief interval) additional chemical potential energy as a result of at least one of the electrons in it occupying an orbital with higher energy than the orbital(s) the electrons in the same atom would occupy in the ground state of the atom.
What is the difference between photon and neutron?
Neutron is a neutral particle present within the nucleus of an atom. Proton is a positively charged particle present within the nucleus of an atom. Photons are particles of light.
A neutral atom of gold has a mass number of 197 and has 118 neutrons how many electrons does it have?
Any neutral atoms has the same number of electrons as protons, and any atom has a number of protons equal to the difference between its mass number and neutron number. Therefore, this atom has 197 - 118 = 79 electrons.
