In its' elemental state potassium is a soft silvery metal.
Calcium in its normal state is a soft, silver-white metal that is quite reactive with air and water. It is typically found in the form of calcium carbonate in nature, as in limestone and chalk.
It is a yellow solid (normally in powder form) and it smells like Rotorua.
Pure arsenic is usually "grey arsenic". It looks like, well, a metal. Other allotropes do exist, but quickly transform into grey arsenic under normal conditions.
It is shiny but starts to turn darker straight after being cut.
To determine the number of potassium atoms in the reactants of a chemical reaction, you would need to look at the chemical equation for the reaction and count the number of potassium atoms on the reactant side. The coefficient in front of the potassium-containing compound in the reactants indicates how many potassium atoms are present in that compound.
it looks like gas,
solid
The appearance of francium is not known.
Potassium nitrate is white.
Californium has a silvery metallic appearance.
It is a shiny silver colored metal
Potassium nitrate is solid state of matter. and look like as shown in the figure. I've added a diagram for your easiness
Argon is a colorless, odorless gas in its normal state. It is a noble gas that is not reactive with other elements.
Neptunium is a solid metal with a metallic appearance.
Titanium in its normal state is a silver-colored metal with a shiny surface. It is lightweight, strong, and resistant to corrosion.
It is a colorless noble gas, so you can't really see it.
Calcium in its normal state is a soft, silver-white metal that is quite reactive with air and water. It is typically found in the form of calcium carbonate in nature, as in limestone and chalk.
