Answer:
high density, malleable, ductile, can corrode, good conductors,
Explanation:
gold's density is 19.3 g/cc compared to something like water which is 1g/cc
aluminum is extremely malleable, it can be flattened into thin sheets
copper can be formed into complex forms without breaking like wire, instruments, and bed frames
steel can get corroded by the oxygen particles in the air if it stays out too long.
copper is an excellent example of a conductor, it is used to make wires which conduct electricity that brings "power" into things like lights, computers, and TVs

Comets are objects in the space that is composed mainly of dust and ice. While approaching the sun, a tail grows. Comets have nucleus which represents the hard rock object. As it nears the sun, it heats up the comet causing it to vaporize. Meteors, on the other hand, are what we call "shooting stars". They are interplanetary dusts that burn up as it approaches the Earth's atmosphere.
