Argon is a noble gas. At S.T.P. it is a colourless odourless gas.
Argon is a colorless, odorless gas in its normal state. It is a noble gas that is not reactive with other elements.
Xenon is not visible so in gaseous form,it is odorless and colorless.
The density of argon at 100 degrees Celsius is approximately 1.784 grams per cubic centimeter.
K - Potassium. Just look at atomic numbers on periodic table! potassium
An atom of argon consists of a nucleus composed of 18 protons and usually 22 neutrons surrounded by 18 electrons in energy levels. The nucleus is very small compared to the electron cloud, which extends far out around the nucleus. The overall structure is spherical and symmetrical due to the arrangement of the electrons in their respective energy levels.

The appearance of francium is not known.
Californium has a silvery metallic appearance.
It is a shiny silver colored metal
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.
At its normal state, copper appears as a reddish-brown metal with a shiny metallic luster. It is ductile and malleable, making it easy to shape into various forms.
