Sodium is a member of the alkali metal family with potassium (K) and Lithium (LI) sodium's big claim to fame is that it's one or two elements in your table salt. when bonded to chlorine (CI) THE two elements make sodium chloride
2H2O➡2H2+O2 is the correct balanced equation of decomposition
Because decomposition means a molecule breaking down in to segments
The atomic number of an element is characteristic to that element. Atomic number is the number of protons of that element.
Mass number is the sum of protons and neutrons of the element.
since protons and neutrons have a mass of 1 unit each, they together make up the mass of the element.
atomic number - number of protons - 92
mass number - number of neutrons + protons = 234
number of neutrons = mass number - atomic number
neutrons = 234 - 92 = 142
answer is 142
