A. an atom is the smallest particle of an element that can participate in a chemical reaction. molecules is combination of more than one atoms. protons is the positively charged of particle. neutrons is neutral that is no charged.

Can an atom become excited by absorbing a photon of visible light?
Q. Can an atom become excited by absorbing a photon of visible light? I have read that LED's can be used to excite the hydrogen atom at a frequency of 1-65hz. If so, what wavelength (in NM's) would the led be and how far could it excite the hydrogen atom?
Asked by Brad K - Sat Jun 21 11:00:21 2008 - - 2 Answers - 0 Comments
A. An atom can be excited by a photon if and only if that photon carries the correct amount of energy to kick the atom into a higher energy level. So look up the hydrogen spectrum (in particular, the Lyman series, the transitions involving the ground state) to see the energies/frequencies/wave lengths of light that will work. Of course, the energy of a photon is: E = h * frequency = h * speed of light / wavelength, where h is Planck'c constant.

Physics: How energy is there in one atom? Or is there a periodic table that shows it for each atom?
Q. This maybe sounds like a dumb question. I should say which atom, right? O, how much in 1 hydrogen atom and 1 lead atom, happy now? Usually when raeding a magazine article they quote in comparison to the A Bomb at Hiroshima for instance? Ok and I also mean TOTAL energy, not just what can/could be released by nuclear fusion/fission(?) I've been wondering this for years!

When a hydrogen atom absorbs a photon, what is it that causes the increase in energy?
Q. Just trying to find out, does the photon absorption cause the hydrogen atom's proton and neutron to be held together with a stronger force? If so what kind of force is it? Is it an electromagnetic force?

A. Nothing happens per say in the nucleus. Taking the electron transitions associated with visible and ultraviolet interactions with matter as an example, absorption of a photon will occur only when the quantum energy of the photon precisely matches the energy gap between the initial and final states. In the interaction of radiation with matter, if there is no pair of energy states such that the photon energy can elevate the system from the lower to the upper state, then the matter will be transparent to that radiation. If an electron is already in an excited state (an upper energy level, in contrast to its lowest possible level or "ground state"), then an incoming photon for which the quantum energy is equal to the energy difference… [cont.]

A. No, electrons behave nothing like planets, they only appear to if you draw out their path on paper. In fact, electrons are not particles in the strictest sense - They are particles and waves at the same time, and as such, they do not follow a simple circular path like on atomic models. Moreover, electron paths are almost never circular(The 1H hydrogen being an exception), but they assume a variety of trajectories(known as orbitals).

The radius of the nucleus of hydrogen is on the order of 10-13 cm so that its volume is on the order of 10-39 cm3 (cubic centimeter); its mass is about 10-24 g (gram).

A. An electron is stripped away from the atom. this results in one more proton than electron and gives atom a positive charge. Electron could be stripped away if it was alone on its valence shell and hence atom would have easier time getting rid of electron than absorbing more to fill up shell. examples are sodium and potassium

A. An atom is neutral. However, atoms can turn into ions, which are charged. Generally, nonmetals turn into negative ions (they gain electrons) and metals turn into positive ions (they lose electrons) to create an ionic bond. Charges occur because of the fact that electrons are negative subatomic particles.

Q. I can't find the answer in my biology text book but the question's on my study guide. I've also looked through google but haven't been able to find anything. So, how do the parts of an atom contribute to the atom's mass?

A. acids are often mixed with bases to make salts. the positive ion from the base & the negative ion from the acid usually combine to make a salt after the other product water is evaporated off. NaOH & HCL --> NaCl & H2O NH4OH & H2SO4 --> (NH4)2SO4 & H2O
