Answer:
Polycrystalline cells are less expensive to make than single-crystalline modules but are also slightly less efficient than the single-crystalline (12% -15%). Also, it has been found that amorphous silicon cells dominate in warm, sunny conditions due to their lower power-loss temperature coefficient [1]
Explanation:
Answer:
11 protons and 11 electrons.
Explanation:
Na is a neutral element and element number 11.
This means that it has 11 protons and 11 electrons.
In order to create an isotope, you would add or get rid of neutrons to get different mass numbers but the same element. The number of protons and electrons would remain the same.

Answer:
liquid, solid, and gas
Explanation: It depends where the molecules are moving. When a solid the molecules are vibrating and are all together, compact, the molecules are also very slow. When a liquid the molecules are moving back and forth, up and down, and are less compact, but moving faster. When a gas, the molecules move everywhere very quickly, moving super fast.
