Water, stars and fuel cells. Hydrogen atoms are part of water and many biological molecules. Hydrogen gas is used to produce ammonia and can supply fuel cells.
Identify hydrogen from its proton count.
Count the neutrons in Hydrogen-1.
Inspect the occupied electron shells.
Compare the valence shell with a neighbouring element.
Explain what changes when an electron is lost.
A hydrogen atom is H; hydrogen gas usually contains H₂ molecules. Hydrogen-1 has no neutron.

Identify hydrogen from its proton count.
Check your understanding
What identifies an atom as hydrogen?
1 protons. Atomic number is proton count. Every hydrogen nucleus has 1 protons.
How many neutrons are in Hydrogen-1?
0. Neutrons = mass number − atomic number = 1 − 1 = 0. Mass number is not the average atomic weight of natural samples.
How many electrons are in a neutral hydrogen atom?
1. A neutral atom balances 1 positive protons with 1 negative electrons.
Which shell count describes neutral hydrogen in its ground state?
1. 1s¹ gives 1 electrons across its occupied shells. Circular paths are only diagram guides.
If this atom loses one electron, what happens to its net charge?
It becomes +1. Losing one negative electron leaves one more proton than electrons. Its 1 protons still identify it as hydrogen.
What can this 3D shell model tell you reliably?
The particle counts for the selected neutral isotope. The counts represent a defined isotope and neutral atom. Particle sizes, spacing and circles are simplified teaching symbols.
