Hydrogen is a gas at Standard Temperature & Pressure {0°C & 1 atmosphere}
At standard temperature and pressure (STP), iodine is a solid while hydrogen is a gas.
Calcium is a solid at room temperature and pressure.
Gas. For hydrogen to become a liquid, you need to cool it down to 20.28 K, which is -252.87 degrees Celsius, or -434.45 degrees Fahrenheit if that is more your style.
Argon is a gas at STP. It becomes a liquid below -186oC and solid below -190oC at StP
solid with hydrogen bonds making it less dense than its liquid form

It is a gas and a liquid
At standard temperature and pressure (STP) hydrogen is a gas and water is a liquid.
At standard temperature and pressure (STP), carbon is a solid while hydrogen is a gas. Carbon exists as a solid in various allotropes such as graphite and diamond, whereas hydrogen is a diatomic gas at STP.
solid with hydrogen bonds making it less dense than its liquid form
Hydrogen exists in a gaseous state at room temperature and pressure. It is the lightest and most abundant element in the universe. Hydrogen can also exist in a liquid state at extremely low temperatures, below its boiling point of -252.87°C.
Heat it.
At standard temperature and pressure (STP), which is defined as 0 degrees Celsius and 1 atmosphere of pressure, argon is a gas. It has a boiling point of -185.7 degrees Celsius, meaning it turns into a liquid at temperatures below that.
