Explanation:
The reaction expression is given as;
2H₂ + O₂
→ 2H₂O
From the balance reaction expression:
2 mole of hydrogen gas combines with 1 mole of oxygen gas on the reactant side;
This produces 2 mole of water on the product side of the expression.
The product is in liquid form.
This reaction is a synthesis reaction because a single product is formed from two reactants.

- in case cesium-129 is what you were referring to.
Cesium has atomic number as seen on a modern periodic table. A cesium atom nucleus would thus contain an equal number of protons; in addition to that, a <em>neutral</em> atom of cesium would contain the same number of electrons in its electron cloud.
For a particular isotope,
.
This isotope of cesium has a mass number of and contains
protons in each atomic nucleus. One cesium nuclei would therefore contain
neutrons.
