How do Spectra from neutral atoms compared with spectra from ionized atoms of the same element?
Spectra from neutral atoms show a series of discrete lines corresponding to transitions between different energy levels within the atom. These lines are unique to each element and can be used to identify the element. When an atom is ionized, electrons are removed, leading to changes in the energy levels and resulting in a different set of spectral lines. The spectra from ionized atoms will have different line patterns and energy levels compared to those of neutral atoms of the same element.
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.
What is the difference between emission and absorption?
Emission is the process where an object releases energy (such as light) while absorption is the process where an object takes in energy (such as light). In emission, energy is being emitted from the object, whereas in absorption, energy is being absorbed by the object.
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.
Which of the Following statements about helium atom in the sun and helium atom on earth false?
Both helium atoms in the sun and on Earth have the same properties, as they are identical in terms of their atomic structure and behavior. The only difference is in the environment in which they exist.
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?
An excited atom is electrically neutral because the number of protons in the nucleus is equal to the number of electrons surrounding the nucleus. When an atom becomes excited, its electrons move to higher energy levels but the total negative charge from the electrons is still balanced by the positive charge from the protons, maintaining the atom's neutrality.
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.
According to Bohr's theory an excited atom would?
radiate energy
If an atom has 80 protons and 121 neutrons and is not in an excited state how many electrons does the atom have?
The number of electrons in a neutral atom is equal to the number of protons, which is 80 in this case. This is because in a neutral atom, the positive charge of the protons is balanced by the negative charge of the electrons.
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.
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 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.
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 charge of a model atom element?
The charge of an atom is the difference between the number of protons and the number of electrons. Normally they balance, so the charge is 0. If there are extra electrons, the atom is an ion, and is considered negative. Conversely, an excess of electrons means positive.
