In an ionic bond, the atoms are bound together by the attraction between oppositely-charged ions. For example, sodium and chloride form an ionic bond, to make NaCl, or table salt.
Igneous rock is formed through the cooling and solidification of magma or lava. Igneous rock may form with or without crystallization, either below the surface as intrusive (plutonic) rocks or on the surface as extrusive (volcanic) rocks.This magma can be derived from partial melts of pre-existing rocks in either a planet's mantle or crust.gneous rock may form with or without crystallization, either below the surface as intrusive (plutonic) rocks or on the surface as extrusive (volcanic) rocks.
Igneous rocks are formed from rocks that have been he â¦ ated so much they melt. When they cool they make new, igneous, rocks. If it's magma that cools that means it's still under the earth's crust so the igneous rock is intrusive. If it's lava that cools after flowing down a volcano it's an extrusive igneous rock that's formed.
