Gas Phase
Hydrogen's normal phase is a gas at room temperature and pressure.
Hydrogen is a gas in normal conditions.
Hydrogen is a gas at room temperature and pressure, making it the normal phase for this element.
Hydrogen is normally found in a gas phase at room temperature and pressure.
Hydrogen can be an atom (H1), a molecule (H2 or normal hydrogen), an isotope such as deuterium or tritium. Ionized Hydrogen is simply a proton.
Is this HO2 for hydrogen dioxide, never heard of it in 'normal' life
a gas
Normal hydrogen has one proton and no neutrons in its nucleus, so it has a mass of one. Heavy hydrogen often called deuterium has one proton and one neutron, so it has a mass of two instead of one. There is also tritium which has one proton and two neutrons, so a mass of three.
nope..
by looking at your ugly face
Depending on the temperature, hydrogen can exist in three states of matter (forms), viz., gas, liquid, and solid. Also hydrogen has three isotopes, viz. protium, deuterium, and tritium. This depends on the number of neutrons present in the nucleus. protium ; 0 neutrons ; The most common isotope of hydrogen deuterium ; 1 neutron ; known as 'heavy hydrogen'. tritium ; 2 neutrons ; known as 'super-heavy' hydrogen, and it is also radio-active. NB When describing as 'forms' you need to be more specific, re. isotopes, states of matter , or any other characteristic.
this sucks
