Compounds are made when atoms of 2 different elements are combined in regular forms.
Repeating patterns of either atoms (one element) or molecules (2 or more elements), or perhaps ionic bonded atoms (2 or more elements, ionic bonds) are found in solids.
The most regular patterns are found in crystals which is a type of solid.
No, the splitting of atoms is nuclear fission.
Fusion is nuclear synthesis, combining atoms of lesser mass into atoms of greater mass. Decay is reducing the mass of larger (unstable) atoms to form atoms of lesser mass.
Radioisotopes are "radioactive isotopes"; they are not stable. Radioactive atoms will decay, or break apart into other atoms, by emitting an electron, or a neutron or a positron or an alpha particle (2 protons and two neutrons). The rate at which this happens is measured by the "half-life"; after one half-life, half of the atoms will have decayed. After another half-life, half of the remaining atoms will have decayed. Atoms with short half-lives are highly radioactive, and can be fairly dangerous. Atoms with long half-lives are only slightly radioactive, and aren't all that dangerous.
Statistically carbon-14 atoms decay at a constant rate.
Radioactivity is caused by unstable atoms, that break apart.
a solid
This is a solid.
The type of solid that has repeating patterns of atoms are crystals.
Crystals.
The atoms are arranged in repeating patterns.
minernerals
The atoms in glasses are organized in regular patterns
The atoms or molecules form repeating patterns.
crystals
i think its called a mineral
False. In a crystalline structure, atoms are in an orderly arrangement.
They form what is called a crystal. for more information on crystals you can read the Wikipedia article: http://en.wikipedia.org/wiki/Crystal
