Solder is a metallic alloy
yes
It is a mixture
A metallic compound uses its sea of electrons, which are delocalized throughout the compound, to have higher ductility.
it is not metallic SO2 is a non-metallic compound
The compound symbol for solder can vary depending on the specific composition. Common solder compounds include tin-lead solder (Sn-Pb) and lead-free solder such as tin-silver-copper (Sn-Ag-Cu) or tin-copper (Sn-Cu).
Neither. It is classified as a compound.
Iron is not a compound, it is a metallic element.
Gypsum is a salt (a compound made of both metallic and non-metallic elements).

Chlorine is a nonmetal but its is an element, not a compound.
The process is called soldering. It involves applying heat to the solder, a low-melting-point metal alloy, which then melts and flows between the two metallic surfaces. As the solder cools and solidifies, it forms a strong electrical connection between the surfaces, enabling the flow of current.
that would be a metallic compound.
