What are chemical properties of steel?
Carbon is the principal hardening element in steel.
Hardness and strength increase proportionally
as Carbon content is increased up to about 0.85%. Carbon has a negative effect on ductility, weldability and toughness. Carbon range in ULC Steel is usually 0.002 – 0.007%.

Is Half Life a chemical property?
Half-life – This chemical property is
the amount of time it will take for half of the original substance to decay
. It is used in nuclear chemistry and nuclear physics to describe the time required for half of the unstable radioactive atoms in a sample to experience radioactive decay.
Is color a chemical property?
Characteristics such as melting point, boiling point, density, solubility, color, odor, etc. are physical properties. Properties that describe how a substance changes identity to produce a new substance are chemical properties.
