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" ? ...

... Credit Copyright: ESO Explanation: Is this what will become of our Milky Way Galaxy? Perhaps if we collide with the Andromeda Galaxy in a few billion years, it might. Pictured above is NGC 7252, a jumble of stars created by a huge collision between two large galaxies. ... Since the sideways velocity of the Andromeda Galaxy (M31) is presently unknown, no one really knows for sure if the Milky Way will ever collide with M31 . ...

. 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!")

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. ...

Plasma is sometimes called "the fourth state of matter", beyond the familiar three--solid, liquid and gas. It is a gas in which atoms have been broken up into free-floating negative electrons and positive ions , atoms which have lost electrons and are left with a positive electric charge. ... The fluorescent lamp , widely used in the home and at work, contains plasma (main constituent, mercury vapor) which is heated and agitated by electricity, from the power line to which the lamp is connected. ...

... 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 |...
