<h2><u>Answer:</u></h2>
The quantity of protons likewise decides the character of the component. Electrons have a negative charge. The furthest or valence electrons of a particle are the ones that partake in synthetic responses. A component's substance properties rely upon its valence electrons.
The general properties of issue, for example, shading, thickness, hardness, are instances of physical properties. Properties that portray how a substance changes into a totally extraordinary substance are called synthetic properties. Combustibility and consumption/oxidation obstruction are instances of compound properties.
