It has only single bonds.So it is saturated
Yes it’s for the good of ways
Answer:
Erosion occurs through deflation, and sand that was picked up is deposited against an obstruction.
Explanation:
Erosion can be defined as a geological process which involves the wearing away of earth material and transportation of these material to another location by Natural agents such as wind and water. Erosion involves removal of top soil, rocks and other earth particles by action of wind, glacier and water.
Wind causes erosion by deflation. Deflation is the actual removal of grain of rocks . Generally, it s the lowering of land surface that happens as a result of removal of surface particles(sands grains) by wind. Deflation is usually prevalent in arid areas. This sand can later be picked up and deposited to form sand dunes . Sand dunes are mounds of sand formed by wind . This sands are sheltered by an obstacle. And sand dunes are prevalent in desert and or along the beach. The sand dune grows as sand accumulate.
<span>b) a positive metal ion and a negative nonmetal ion.
</span>Because generally ions of non-metal elements (such as the halogens) are negatively charged while ions of metal elements (such as the alkali earth metals) are positively charged. The differences in their changes causes strong electrostatic attraction (an ionic bond).
There are negative ions and positive ions known as anions and cations.
Atoms of elements (besides the noble gases) are not stable.
These atoms lose or gain electrons to gain the stable electronic configuration of a noble gas which has either 2 electrons or 8 electrons in the valence shell.
Since an atom is neutral, once it loses or gain electrons, it gains charge and is known as an ion
