Group 1a elements (the first column on the left side of the Periodic table) always release one electron to form positive ions with a charge of +1. Group 7a nonmetals (the <em>second to the last </em>column on the right side- the rightmost column are the noble gases) always desire to gain one electron to form negative ions with a charge of -1.
Since their charges are equal and opposite, they will always combine in a 1:1 ratio.
The answer is: They have no freedom to move.
However is not completely true, as even in a solid atoms still a move a bit (vibrations).
If atoms were able to slide past each other, then we would have a liquid not a solid. Liquids "flow" but never really "break apart" this is because atoms are sliding between them, think of these as a bucket of marbles rolling down a slope.
If they are free to move in all directions, then you have a gas; that's why someone uses perfume in a room, eventually everyone smells it.
Zinc is also used in alloys such as brass, nickel silver and aluminium solder. Zinc oxide is widely used in the manufacture of very many products such as paints, rubber, cosmetics, pharmaceuticals, plastics, inks, soaps, batteries, textiles and electrical equipment.
Answer: Sediment Transport by Wind
Explanation: Like flowing water, wind picks up and transports particles. Wind carries particles of different sizes in the same ways that water carries them (Figure below). Tiny particles, such as clay and silt, move by suspension. They hang in the air, sometimes for days.
