An atom is the smallest "piece" of an element that still has the properties of that element. For example, an atom of gold is the smallest piece of gold that still acts like gold ? ... When many atoms come together, atoms tend to form molecules. A molecule is a combination of two or more atoms bonded together. For example, a molecule of water (designated by the symbol H 2 O) consists of two hydrogen atoms and an oxygen atom which are in a "relationship" ? ...

the atoms includes descriptions of the telescope, its components and instruments, as well as detailed measurements. the reports are indexed as shown below. as there is often overlap between categories, a memo may appear under more than one category. the memos are referenced by year-number (i.e. 99-01), the number assigned in the order the memo is received. please note the date of the memos; information contained in the memos may have evolved over time. atoms directory: . ...

. A hydrogen atom and a helium atom go into a bar. The hydrogen atom is clearly upset and moans, "I've lost my electron, my only electron." The concerned helium atom says, "Just calm down now ... are you sure you've lost it?" . The hydrogen atom replies, "Yes, I'm positive!" . (Later, a neutron walks in to the same bar. He sits down and says to the bar tender, "Hey, how much for a beer?" The bar tender looks at him and says, "For you, no charge!")

... 4a. Electric Fluid . ... Matter consists of atoms, and atoms consist of electrically charged components--lightweight negative electrons , and positive nuclei . ... In one end we embed a metal coil of wire (like that of a flashlight bulb) in the other a metal plate, as drawn. ... As the wire begins to glow, a current begins to flow, because now negatively charged particles are emitted from the hot wire, are attracted to the positive charge on the plate and by doing so, complete the electrical circuit...

The linelist format used by the Belfast line formation code SPECTRUM is a convenient means of storing atomic data needed for LTE line formation calculations. ... Atomic data for transitions in specific ions are stored in individual files ( e.g. He1.d, C1.d, C2.d, .. The individual line data include atom and ion identifiers, wavelength, oscillator strength, electron and radiative damping constants, excitation potential of the lower level in a transition, a multiplet identifier, and reference codes. ...

Although seen here on Earth, aurorae start at the center of the solar system. ... After about three days those particles get near the Earth and hit the Earth's magnetic field. ... Now these particles are moving very fast, and when they hit the air they slam into air atoms that make up our atmosphere, sometimes knocking loose more electrons. ... 2008 Phil Plait. ...

Astronomers successfully synthesized the distribution of atomic carbon around planetary nebula NGC 6302 in test observations with the ALMA Band 8 receiver, developed by the National Astronomical Observatory of Japan (NAOJ). ... ALMA targeted the center of the nebula, revealing that the distribution of carbon atoms is concentrated in a small part. ...

... Most of the time large telescopes are collecting light for a spectrograph, which spreads the light out into a rainbow. ... Atoms in the cool outer layers of a star absorb light coming from the hotter regions within, producing dark absorption lines across the spectrum. ... And astronomers do not actually use color film to take a color picture of the spectrum, for several reasons: . ... Color film does a very poor job of representing the continuous range of colors in a spectrum. ... Tutorial: Part 1 |...

The foundation of my research program is in astrophysics, where almost all of our knowledge of the universe beyond our solar system derives from detecting light that has been emitted, absorbed, or scattered by atoms.

... For SIMS (Secondary Ion Mass Spectrometry) analysis, a solid surface is bombarded by primary ions of some keV energy. ... The subsequent mass analysis of the emitted ions provides detailed information on the elemental and molecular composition of the surface. ... Extremely short ion pulses with a duration below . ... By rastering a fine-focussed ion beam over the surface, like an electron beam in an electron microprobe, mass resolved secondary ion images (chemical maps) can be obtained...
