Question

define metals and non metals and S P D F​

Answer 1

Answer:

Nonmetal. The elements can be classified as metals, nonmetals, or metalloids. Metals are good conductors of heat and electricity, and are malleable (they can be hammered into sheets) and ductile (they can be drawn into wire).

Metals tend to have a metallic lustre and are opaque as thin sheets, while nonmetallic solids tend to have dull surfaces and are transparent.

SPDF

They are named s,p,d,f .The s, p, d, and f stand for sharp, principal, diffuse and fundamental, respectively. The letters and words refer to the visual impression left by the fine structure of the spectral lines which occurs due to the first relativistic corrections, especially the spin-orbital interaction.

Answer 2

Explanation:

metals-They are positive charged.They are lustrous. They can be drawn in thin sheets.They are a good conductor of heat and electricity.

non-metals-They are negatively and positively charged.They are a bad conductor.Spdf-sharp,principal,diffuseand fundamental
