Covalent bonds
Explanation:
Covalent bonds are formed between two atoms having low or zero electronegativity difference.
This bond type is usually found in the molecules of non-metals.
Properties:
- They are usually gases or volatile liquids or low melting point solids.
- Most of them are usually insoluble in polar solvents.
- They are mainly non-conductors of electric current.
- Their reactions are generally slow.

Answer:
False
Explanation:
Those would affect physical properties not chemical properties.
Answer:
Explanation:
you would use d=m over v which means density = mas divide by volume
This would be an ionic bond. Ionic bonds form between metals and nonmetals due to the relatively large different in electronegativities where nonmetals are more electronegative than metals. This difference in electronegativities makes it so that the metal gives up the electron to make an octet and the nonmetal gains the electron to make an octet (there is no sharing of the electron). The metal becomes a cation while the nonmetal becomes a anion and their opposite electric charges keep them together.
I hope this helps let me know in the comments if anything is unclear.
Answer:
Fluorescent luminaire is the assembly that forms a lamp, called a fluorescent tube, and an armature, which contains the accessories necessary for operation. In certain places, only the lamp is known as a luminaire. The lamp is low pressure mercury vapor discharge and is normally used for domestic or industrial lighting. Its advantage over other types of lamps, such as incandescent lamps, is their energy efficiency.
The lamp consists of a thin glass tube lined internally with various compound chemicals called phosphors, although they generally do not contain the chemical element phosphorus and should not be confused with it. Those chemical compounds emit visible light when receiving ultraviolet radiation. The tube also contains a small amount of mercury vapor and an inert gas, usually argon or neon, at a pressure lower than atmospheric pressure. At each end of the tube is a filament ...
